THE ROLE

We are hiring a Team Lead, Web3 to lead a cross-functional team of frontend, backend, smart contract and QA engineers in Xsolla ZK, Xsolla's Web3 ecosystem on a zkSync-based L2. Your team builds:

• smart wallets built on account abstraction;

• SDKs that game studios and partners use to bring players on-chain;

• infrastructure backend services for tokenizing in-game items and currencies;

• ecosystem dApps: a DEX, an NFT marketplace and an auction.

This is a management role. Most of your time goes to people and delivery: building the team, growing engineers, and making delivery predictable. The rest goes to technical leadership: architecture, reviews and hands-on code where it matters.

RESPONSIBILITIES

WHAT YOU WILL OWN

The team: hiring, onboarding, growth and performance of frontend, backend, smart contract and QA engineers

Delivery: predictable commitments, a sustainable pace and the quality of what the team ships

How the team works: processes, engineering standards and an AI-assisted workflow

Relationships with Product, DevOps and other Xsolla product teams: priorities, dependencies and expectations

The technical direction of the team's product area: on-chain / off-chain architecture and key technical decisions, justified in writing

Security and reliability of what the team ships: signing flows, contracts that hold user assets, production operation and the team's on-call rotation

WHAT YOU WILL DO

People

Set clear goals and expectations for each engineer

Run regular 1:1s, performance reviews and career development conversations; give direct feedback and address underperformance

Hire engineers across disciplines: define roles, run interviews and onboard new people

Grow engineers through mentoring and build the team's next leaders

Build a culture of technical excellence, collaboration and continuous learning

Delivery

Work with Product to shape requirements, estimate and plan work

Manage scope, workload, risks and dependencies so the team delivers on its commitments

Report progress, risks and blockers to stakeholders

Lead the team through production incidents and post-mortems

Continuously improve development processes and team efficiency

Technical leadership

Review architecture and critical code across backend, frontend and smart contracts, with a focus on edge cases specific to Xsolla products: smart wallets, tokenization of in-game items and currencies, marketplace and auction flows

Lead key decisions on smart wallet integration (UserOperations, paymaster and gas sponsorship), session keys and the signing flow

Identify systemic risks (key management, signature phishing, bundler and RPC dependencies) and make sure they are addressed before they become incidents

Contribute hands-on to critical features when needed

Set up AI tooling in the repositories (Claude Code, Codex, Cursor: rules, context, harness) and drive its adoption across the team

REQUIRED

Management experience

5+ years of engineering management experience

Managing cross-functional teams that combine several disciplines (for example frontend, backend, smart contracts and QA)

Teams you led shipped dApps to production and maintained them

People leadership

Hiring and building teams: defining roles, running interviews, onboarding

Performance management: setting goals, giving feedback, running performance reviews, handling underperformance

Growing engineers: career plans, mentoring

Delivery and stakeholders

Delivery planning: estimation, sprint planning, managing scope, risks and dependencies

Working with Product and other teams on priorities and trade-offs; explaining technical trade-offs to non-technical stakeholders

Leading a team through production incidents and post-mortems

Balancing management with hands-on technical work

Technical depth

A strong technical background: hands-on engineering experience across the Web3 stack, deep enough to lead technical decisions and review work on each layer:

Web3 libraries and wallets: viem and wagmi in production; how wallet signers work (EOAs, browser and embedded wallets, smart accounts, EIP-191, EIP-712, EIP-1193); smart wallets (UserOperations, paymasters, ERC-1271)

Backend: Go and TypeScript (Node.js); processing on-chain events (idempotency, reorgs, retries); asynchronous messaging (Kafka, RabbitMQ or NATS); PostgreSQL and Redis; REST and gRPC API design

Frontend: React and TypeScript; web security fundamentals (XSS, CSRF, CSP, safe handling of signatures and keys in the browser)

Smart contracts: reading Solidity and the EVM (storage, gas, proxy upgrade patterns, access control); common vulnerability classes (reentrancy, front-running / MEV, oracle manipulation, signature replay)

Operations: Docker, Kubernetes, CI/CD; observability (we use Datadog; experience with Prometheus, Grafana, ELK / Graylog or OpenTelemetry also counts)

AI-assisted engineering

Daily hands-on use of AI coding tools (Claude Code, Codex, Cursor) for development and review, including configuring them for a repository

English

Spoken English at B2 level or higher

NICE TO HAVE

ZK Stack and zk-rollups: EraVM vs EVM, system contracts (ContractDeployer, NonceHolder), L1↔L2 messaging, bridging and finality

Smart contract development in Solidity with Foundry

Deeper account abstraction: ERC-4337 EntryPoint versions and validation rules (ERC-7562, ERC-6492), modular accounts (ERC-7579 / ERC-6900), session keys and delegated permissions (ERC-7710 / ERC-7715), EIP-7702

Hands-on experience with wallet and AA infrastructure technologies (Sequence, thirdweb, Privy, Dynamic, Turnkey, Pimlico, Alchemy, ZeroDev, Safe{Core}), with clear views on build versus buy

Key management: HSM, MPC / threshold signing, social or guardian-based recovery

DeFi (DEX, AMM) and NFT marketplaces (ERC-721, ERC-1155, auctions)

go-ethereum and abigen

Managing distributed or remote teams

Gaming or fintech experience with high-load systems

HOW WE WORK

Decisions in writing. Significant technical decisions are written up as an RFC or ADR that lays out the options and trade-offs. We discuss the document, not a blank whiteboard.

AI is part of everyday engineering. We use AI coding tools for development and review, and we treat configuring them for a codebase as real engineering work.

HOW WE HIRE

1. Intro call. Your background, your motivation and the role.

2. Technical interview. Built on the Technical depth part of the Required section and the technical items in What you will own.

3. People and delivery. Built on the Management experience, People leadership and Delivery and stakeholders parts of Required: real situations from your experience with hiring, performance, delivery and incidents.

4. Bar raiser. An engineer from outside the hiring team checks that you raise the overall engineering bar.

BENEFITS

We are passionate about fostering a supportive environment for our team, so we prioritize the physical, mental, and emotional well-being of our employees and their families through a comprehensive Benefits Program.
