Engineering Generalist - Product Impact (Full Stack)

Pocket is a Y Combinator W26 company building a premium hardware plus software product in the AI voice recorder space. We are obsessed with quality and speed. We are scaling very fast in the US and now European markets and building a device experience that can become the category leader.

Pocket is building a category-defining platform for ambient intelligence. We need an engineer who can work across backend + frontend to ship the highest-leverage product and growth improvements - whatever moves the needle.

• End-to-end projects: instrumentation → backend services → web/app UI → rollout & iteration.
• Build and iterate on user-facing product features (activation, retention, paid conversion, core UX).
• Design, implement, and scale backend systems: APIs, data models, pipelines, jobs, reliability.
• Improve frontend surfaces where it matters (web product, internal tools, landing pages, onboarding flows).
• Drive experiments: set hypotheses, ship fast, measure results, and harden what works.
• Work closely with design, product, marketing, and support - and help unblock them with code.

What success looks like

• Shipped features/experiments that measurably improve activation/retention/revenue.
• Reliable systems with clear observability (logs/metrics/traces) and pragmatic correctness.
• Clean, simple architecture that stays fast to iterate on as the product evolves.
• High ownership: you proactively find the most important problems and solve them.

• Have strong backend fundamentals (APIs, DBs, async jobs, caching, performance, reliability).
• Can comfortably ship frontend changes (React/TypeScript or similar), even if it’s not your “main thing.”
• Care deeply about product outcomes and can translate ambiguity into shipped work.
• Prefer shipping and learning over long debates; you can move quickly without breaking things.
• 6–10+ years of experience shipping production software (startup pace preferred).

What we care about most

• Performance and reliability by default: profiling, latency budgets, graceful degradation, and pragmatic correctness.

Nice-to-haves

• Experience running experiments / analytics instrumentation (events, funnels, cohorts).
• Experience building internal tools that make teams faster.
• Startup / zero-to-one experience.
