Technical Product Owner (Backend-savvy, No Coding) — Real-Time Web & APIs Goal: Own the tech conversations and delivery: translate vision → specs, align developer + architect, make backend decisions fast, and hold acceptance criteria. No implementation work. What you’ll do (ownership, not coding) Specs & Backlog: Write PRD-lite stories with clear acceptance (latency, bundle, a11y, security). Architecture Decisions: Evaluate options (API shape, auth model, data schema, caching, queues, rate limits, idempotency) and document Decision Records. Milestones & QA gates: Define phases with pass/fail checks; verify with metrics (p50/p95 latency, error rates). Vendor/Candidate Flow: Shortlist, interview, set small paid tests, recommend hires. Risk & Compliance: Call out PII handling, logging redaction, key rotation, least-privilege. Stakeholder comms: Weekly one-pager: shipped / next / risks / asks. You should know (conceptually) APIs & Realtime: REST/GraphQL, WebSockets; OAuth2/API keys; retries/backoff; idempotent writes. Data & Caching: PostgreSQL schema/indexing, migrations; Redis for cache/queues; pagination (cursor). Infra basics: Docker/CI/CD, staging vs prod, health checks, observability (metrics + logs). Performance targets: API p50 ≤ 200 ms, realtime fan-out ≤ 500 ms (staging), error rate < 1%. Security hygiene: secrets management, audit trails, minimum scopes. Nice-to-have: Supabase, serverless edge (Vercel/Cloudflare), ASR/TTS loop basics, R3F/Three.js constraints. Acceptance (for your role) PRD-lite for each item (user story, acceptance, constraints, edge cases). Decision Records (1–2 per week) with rationale & impact. Milestone plan with measurable gates; weekly update sent. Hiring support: shortlist + interview notes + a 2–4h paid test brief per role. Quality gate audit: verify metrics & logs meet acceptance before sign-off.
