Product Engineer

About the Role 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. What You'll Do • 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. What we offer • Purpose: The opportunity to contribute to making AI a public good • Growth: A self-directed environment where you can take initiative to shape your role and career • Compensation: Market-competitive compensation including, for most roles, exposure to pre-launch tokens In addition, 0G Labs is committed to the health and well being of all of our team members. To that end, we provide reimbursements towards a holistic set of experiences and courses: • Core self: Transcendental Meditation • Mind: Landmark Education • Emotion: Art of Communication • Presence: Speech Coach • Body: Fitness, gym and exercise memberships/classes Find Jobs in Germany on Arbeitnow
