Product Engineer

We’re looking for a product engineer who takes ownership of outcomes, not just assigned tasks. You’ll work across 4–5 products with different technology stacks, identify high-value problems, and carry solutions through design, implementation, testing, documentation, delivery, and operation.

• →

  Understand our apps and the 0G stack well enough to improve the shared platform, not only one feature.

• →

  Solve root causes and make durable decisions using shared systems instead of introducing band-aids or
  duplicated solutions.

• →

  Own features end-to-end across UI, APIs, server logic, infrastructure, and deployment; do not stop at the layer you are most comfortable in.

• →

  Build and improve AI-agent infrastructure, including LLM streaming, tool orchestration, sandboxed execution, and security boundaries around untrusted code.

• →

  Understand wallet-based identity, signing, embedded and external wallets, and server-side authorization without conflating wallet connection with application access.

• →

  Independently manage dependencies, reviews, blockers, and delivery while raising genuine product decisions and risks early.

• →

  Raise the bar through meaningful tests, sharp PR reviews, and living documentation that stays true to the product.

• →

  Be open to adopting new technologies, AI tools, and better working practices.

• →

  Be reliable enough that when you own an area, the rest of the team can confidently focus on building and expanding other products.

• →

  Treat “done” as delivered, verified, and operating—not merely coded or test-green. Run what you ship with structured logs, traces, metrics, dashboards, alerts, first-line technical support, optimization, and ongoing support for internal teams and external users.

Technical background:

• →

  Strong end-to-end TypeScript and React experience across client, server, API design, and serverless or edge runtimes. Remix, Next.js, Vite, and Cloudflare Workers experience is valuable.

• →

  Experience building LLM-powered products beyond basic API calls, including streaming, tool use, prompt pipelines, agent orchestration, or sandboxed execution.

• →

  Comfortable with web3 application development, wallet authentication, signing, embedded and external wallets, and EVM fundamentals.

• →

  Hands-on experience with infrastructure as code, CI/CD, containers, production observability, and behavior-driven testing.

• →

  Our stack includes pnpm, Terraform, GitHub Actions, Docker, Fly.io, Grafana, OpenTelemetry,Prometheus, Vitest, and Playwright.
