The Rise of the Web3 Specialist

TL;DR

• Web3 engineering is splitting into deeper specialties as protocols become more complex.
• Areas such as ZK, protocol design, interoperability, security, infrastructure, wallets, and developer tooling increasingly require focused expertise.
• Experienced crypto developers now produce a large share of open-source activity, while more developers work across several ecosystems.
• Hiring teams need a clearer understanding of the exact technical problems each role will solve.

A few years ago, many companies could advertise for a blockchain developer and receive candidates whose experience covered most of what the team needed.

The industry was smaller, the stacks were simpler, and many engineers worked across smart contracts, backend services, frontend applications, infrastructure, and integrations at the same time.

That environment is changing.

Modern Web3 has grown into a collection of technical fields that require very different forms of expertise. Protocol engineering, zero-knowledge systems, wallet infrastructure, interoperability, formal verification, validator systems, cryptography, developer tooling, data infrastructure, and smart contract security can now develop into careers of their own.

A team building a rollup faces different engineering problems from a company building a wallet. An interoperability protocol needs different expertise from a DeFi application. A zero-knowledge proving system demands skills that may sit closer to cryptography and systems engineering than ordinary application development.

Web3 companies are starting to need people who understand these specific problems deeply.

That is driving the rise of the Web3 specialist.

The Industry Has Accumulated Technical Depth

Web3 has had enough time to develop experienced engineers who have spent several years inside specific parts of the ecosystem.

Electric Capital’s 2024 Developer Report found that established crypto developers, defined as developers with at least two years of experience in the industry, grew 27% year over year and produced 70% of measured code commits. The same research found that one in three crypto developers now works across multiple ecosystems.

These developers have lived through several generations of technical change.

They have worked through DeFi growth, NFT infrastructure, Layer 2 expansion, bridge development, new virtual machines, account abstraction, restaking, modular architecture, and increasingly advanced cryptographic systems.

Experience begins to separate into deeper areas as these systems mature.

An engineer who spends four years working on consensus systems develops a different technical profile from someone who spends four years building smart contract applications. Both may work in Web3, while their day-to-day engineering problems can be completely different.

For hiring teams, this changes how technical roles need to be understood.

Zero Knowledge Has Become Its Own Engineering Domain

Zero-knowledge technology shows this specialization clearly.

Building ZK systems can require knowledge of cryptographic proof systems, circuits, prover performance, virtual machines, compilers, GPU acceleration, mathematics, and low-level systems engineering.

The Ethereum ecosystem provides a useful example. Recent research into Ethereum’s technical roadmap describes a future where specialized provers generate zero-knowledge proofs for block execution, while validators verify those proofs. The same research covers ongoing work around zkEVMs, proving infrastructure, proof aggregation, and specialized hardware.

This creates demand for people who understand the proving layer itself.

A general smart contract engineer may know how to build on a ZK-based network, while a proof engineer may work much deeper inside the cryptography and execution system that makes the network possible.

Those are different jobs.

Protocol Engineering Is Becoming More Defined

Protocol engineering has also developed into a clearer specialty.

These engineers may work on consensus, execution environments, networking, state management, sequencing, fee markets, validator behavior, or protocol upgrades.

Their work often requires strong knowledge of distributed systems and lower-level languages such as Rust, Go, or C++.

Current hiring activity already separates protocol roles from ordinary product engineering, with positions such as Protocol Engineer, Compiler Engineer, Cross-Chain Engineer, Formal Verification Engineer, and Smart Contract Engineer appearing as distinct roles.

This tells us something important about the market.

Companies increasingly know which layer of their system needs attention.

A protocol team looking for someone to work on execution performance has a very different problem from a product team hiring someone to build user-facing applications.

The recruitment process needs to understand that difference before sourcing begins.

Interoperability Creates Another Specialist Layer

As developers spread across more ecosystems, interoperability becomes a deeper technical field.

Electric Capital found that one in three crypto developers worked across multiple chains in 2024.

That growth creates more demand for systems that move information, assets, and instructions across different environments.

Cross-chain engineers may need to understand messaging systems, bridge architecture, validator assumptions, relayers, light clients, proof systems, settlement models, and the security boundaries between chains.

The work requires knowledge of several systems at once.

This creates another area where broad “blockchain experience” gives hiring teams too little information.

Security Is Splitting Into Specialties Too

Web3 security has also become more specialized.

Smart contract auditing remains important, while the wider security field now includes protocol security, cryptographic review, formal verification, wallet security, infrastructure security, incident response, threat research, and operational security.

Each area requires different knowledge.

A smart contract auditor may focus on state transitions, access controls, economic assumptions, and external calls. A formal verification engineer may work with mathematical proofs and machine-checked properties. A wallet security engineer may spend more time on signing systems, key management, and transaction protection.

Web3 security increasingly looks like a group of technical disciplines with different paths and skill sets.

Infrastructure Has Become Its Own World

Modern Web3 infrastructure can include validators, sequencers, indexers, RPC systems, archive nodes, data pipelines, monitoring platforms, distributed storage, key management systems, and internal developer platforms.

The engineers working in these areas often need strong experience with distributed systems, networking, databases, cloud infrastructure, observability, performance, and reliability.

Blockchain knowledge still matters because these systems behave differently from ordinary web infrastructure.

An indexer needs to understand chain reorganizations. A validator engineer needs to understand consensus. An RPC platform needs to handle chain-specific behavior and unpredictable traffic.

The infrastructure layer now has enough depth to create specialists inside it.

Wallet Engineering Is Becoming Deeper

Wallets have also become more complex.

The modern wallet stack can include account abstraction, smart accounts, transaction simulation, hardware signing, recovery systems, multi-party computation, cross-chain interactions, session keys, identity, permissions, and security monitoring.

That expansion creates new engineering profiles.

A wallet engineer may need to understand cryptography, signing flows, smart contracts, mobile security, browser security, transaction construction, and chain-specific behavior.

The interface may look simple to the user while the engineering underneath becomes increasingly specialized.

Developer Tooling Is Becoming a Serious Technical Career

The people building tools for other Web3 engineers are becoming more specialized as well.

Developer tooling now includes SDKs, compilers, debuggers, testing environments, blockchain explorers, APIs, simulation systems, deployment frameworks, documentation platforms, and monitoring tools.

These engineers need strong technical skills and a deep understanding of how other developers work.

The growth of ZK tooling shows this clearly. ETHGlobal hackathon tracks have included proof aggregation, zkEVM tooling, AI integration, data availability, and application-specific rollups.

The developer experience around these systems has become an engineering problem of its own.

Specialization Changes How Companies Should Define Roles

As the technical landscape becomes more detailed, companies need to define roles around the actual system they are building.

A requirement such as “five years of blockchain experience” provides limited information.

Hiring teams need to know whether the engineer will work on protocol internals, smart contract applications, infrastructure, proving systems, developer tooling, security, wallets, or cross-chain systems.

From there, the company can identify which languages, architecture knowledge, ecosystem experience, and technical depth matter for the role.

This also improves sourcing.

A ZK engineer may appear in cryptography research, proof-system repositories, technical conferences, or specialized developer communities. A protocol engineer may come from distributed systems, blockchain clients, consensus work, or open-source infrastructure.

The market becomes easier to search once the technical problem becomes clear.

Specialists Still Need Wider Context

Deep expertise works best when specialists understand how their area connects to the wider product.

A ZK engineer needs to understand where proving fits into the protocol. A security researcher needs enough architecture context to understand what the system is trying to protect. An infrastructure engineer needs to understand how application behavior affects reliability.

The strongest specialists often develop a deep center of expertise with enough surrounding knowledge to work effectively across teams.

This matters in Web3 because protocol decisions affect infrastructure, infrastructure affects developer experience, wallet behavior affects application design, and security crosses every layer.

The specialist still operates inside a larger system.

The Talent Market Will Keep Splitting

The next stage of Web3 development will likely create even more specialized careers.

Ethereum’s current roadmap points toward deeper work around real-time proving, post-quantum cryptography, privacy, account abstraction, and new validator architectures.

Other ecosystems are developing their own execution systems, interoperability models, data layers, virtual machines, and cryptographic infrastructure.

AI is also entering the stack through developer tooling, automated agents, security analysis, infrastructure management, and on-chain applications.

Each new layer creates new technical problems, and some of those problems will become job categories.

Roles such as smart contract auditor, protocol researcher, ZK engineer, and validator infrastructure engineer once sounded highly unusual. Today, they have established communities and career paths.

The next group of specialties is already forming.

What This Means for Web3 Hiring

Recruiters need to understand the technical market at a deeper level as specialization increases.

A company may ask for a blockchain engineer when the real requirement is much narrower. That lack of clarity makes sourcing harder because the recruiter searches across a talent pool that contains several very different kinds of engineers.

Strong recruitment starts by understanding the problem the person will work on.

The recruiter then needs to identify which background gives someone a reasonable chance of solving that problem.

For highly specialized roles, relevant candidates may also come from outside Web3. Cryptographers can move into ZK systems, distributed systems engineers can move into protocol development, and compiler engineers can work on virtual machines and proving systems.

The technical problem should guide the search.

Who We Are

Veretin Recruitment is a specialist Web3 recruitment company built around few, not many.

We work directly with clients to understand the technical problem behind each role before we begin searching for candidates. Our recruiters research technical backgrounds, speak with candidates directly, review relevant public work, and verify experience before making introductions.

As Web3 becomes more specialized, this research becomes increasingly important because broad titles can hide very different forms of expertise.

Our goal is to understand what the company actually needs and identify the small number of people whose experience matches that work.

For protocols, infrastructure companies, security teams, and other technical Web3 organizations, that means looking deeper than the category of “blockchain engineer.”

The specialist era has already started.
