Roles and Responsibilities
- Build features across the stack — Implement product features that span the React frontend, the GraphQL federation, the Node.js microservices, and the underlying Postgres and ClickHouse stores.
- GraphQL federation work — Add types, resolvers, and subgraph capabilities to the federated Platform API. Keep subgraph boundaries clean. Respect RBAC enforcement at the federation layer.
- Developer experience surfaces — Lift NPS through intuitive UI/UX, fast onboarding, in-browser testing, clear error states, code-snippet generation, and fast time-to-first-successful-call.
- Billing and commerce features — Ship subscription, plan, invoice, payout, and overage features that touch Stripe / PayPal webhooks, the billing state machine, and the usage ledger.
- API catalog and discovery — Improve marketplace search and the API listing experience, including the ranking signals that flow in from the analytics and search stack.
- Observability and quality — Instrument every feature you ship — logs, traces, and metrics are part of the definition of done, not a follow-up ticket. Write the alerts that page you, not someone else.
- Testing discipline — Own unit and integration tests for everything you ship; contribute to the end-to-end and contract test suites that protect the federation and the billing path. A feature without tests is not done.
- On-call and incident response — Take part in on-call rotations; investigate proxy errors, GraphQL federation timeouts, and billing webhook anomalies. You build it, you run it.
- LLM-assisted engineering — Use LLM-based coding and agentic tooling to evolve how features are shipped, reviewed, and tested.
What Success Looks Like
- Features you ship measurably improve activation, time-to-first-successful-call, and developer NPS quarter over quarter.
- The GraphQL federation surface you touch stays fast, well-typed, and intuitive for the next engineer.
- Billing, subscription, and overage flows you build are accurate, auditable, and replayable — providers and consumers trust the numbers.
- ou ship at a confident cadence — PRs land daily, deploys are routine and boring, regressions are rare.
- You leave the code, the docs, and the tests in better shape than you found them.
What You Bring
- 4–7 years of full-stack product engineering experience, with non-trivial work on production systems used by real customers.
- Strong TypeScript/Node.js; comfort writing both frontend (React) and backend services.
- Hands-on GraphQL experience — ideally federation (Apollo Federation / Mercurius / similar), schema design, subgraph composition, persisted queries, performance tuning.
- Solid SQL and comfort with MySQL or Postgres in production; bonus for ClickHouse or Redis experience.
- Familiarity with AWS (EKS, Lambda, Aurora) and containerised deployment on Kubernetes.
- Comfortable with modern observability, feature flags, and CI/CD pipelines.
- Care for developer experience — APIs you would want to consume, docs you would want to read, errors you would want to debug.
- Bonus: experience with billing/commerce systems (Stripe / PayPal), API gateways, rate-limiting, agent protocols (MCP, A2A, x402), or LLM-based developer tooling.
- You are pragmatic, ship-oriented, and comfortable in a system big enough that no one person knows all of it.
We build production software: web products, internal tools, APIs, and on-chain systems when the product needs them.
You own the smart contracts. Design and write Solidity for tokens, access control, issuance, transfers, and ownership on EVM chains. Set roles, events, and pause or upgrade paths. Test and deploy with Hardhat or Foundry, including unit, integration, and fork tests. Work with Product and Backend on ABIs, upgrade plans, and production readiness. Prepare for audits, triage findings, and ship fixes. Keep contracts clear, maintainable, and reasonable on gas. Document the architecture, assumptions, and how to operate what you ship.
What you bring:
- Strong EVM knowledge: gas, storage, events, reentrancy, access control, and common vulnerability patterns
- Hardhat, Foundry, or similar, through deployment
- ERC-20, ERC-721, ERC-1155, Ownable or AccessControl, and proxy or upgrade patterns
- TypeScript or JavaScript for scripts and tests (ethers or viem)
- Production contracts, with care for tests, security, and code quality
- A bachelor's degree in computer science or equivalent experience
- Clear communication with a remote team, and the ability to explain design tradeoffs
- A self-starter who can ship with little supervision
Nice to have: audit work, OpenZeppelin, L2s, account abstraction, permissioned chains, indexing or transaction orchestration, formal verification or static analysis.
