Remote, Czech Republic Universal Hire Full time

What you’ll need (skills & experience): 3++ years building and shipping SaaS with significant 0→1 ownership. Strong React + TypeScript and modern API design; comfortable with relational data modeling, transactions, and indexing. Practical LLM integration: embeddings/RAG, tool-calling/structured outputs, streaming UIs; you can weigh model quality vs. latency vs. cost. Background processing: designing idempotent jobs, retries, schedules, and event-driven workflows. Security & privacy mindset: role-based access, least privilege, auditability, and basic threat modeling. Product sense & communication: you can clarify scope, trade-offs, and deliver shippable increments quickly. Tooling you’ll actually use (illustrative, or equivalent) Web app & APIs: Next.js/React + TypeScript for UI and server routes; tRPC or REST/GraphQL for typed contracts. Data: Postgres (Neon/Supabase/Cloud SQL/Aurora) + Prisma ORM; pgvector for semantic search; Redis (Upstash/managed Valkey) for cache/queues; object storage (S3/R2). AI: OpenAI / Anthropic / Google (plus OSS where it fits) via Vercel AI SDK/direct SDKs; LangGraph/LangChain/OpenAI Assistants for agentic flows where appropriate. Prompt Ops & evals: Langfuse (prompt/version registry & tracing), Helicone/Promptfoo/RAGAS/DeepEval for quality & cost metrics. Background & orchestration: Inngest/Trigger.dev or Temporal; platform crons (Cloudflare/Vercel/EventBridge/Cloud Scheduler). Observability: OpenTelemetry traces + Sentry/Datadog/Grafana Cloud logs/dashboards. Delivery: GitHub Actions CI/CD, per-PR previews; GrowthBook/Unleash feature flags/A-B tests. Auth & enterprise: Auth.js/Clerk/Stytch for auth; WorkOS/Okta for SSO/SAML when needed. Comms integrations: Resend/Postmark/Mailgun (email), Twilio/MessageBird (SMS), Google/Microsoft Graph (calendar). AI-accelerated dev: Cursor, Claude, Copilot/Cody—used deliberately with human-in-the-loop reviews. About us: We’re building a modern, AI-first CRM for recruiting. True greenfield with rapid iterations and real ownership. Goal: MVP in ~60 days, harden for scale by Day 90. You’ll be the cornerstone engineering hire working directly with the founder. Why this role: Massive ownership: set the technical direction and standards from day one. Real product impact: ship AI features that recruiters use daily (search, summaries, matching, automations). Founding-level equity and a fast path to Head of Engineering / early CTO. Compensation & equity Competitive salary + 5–10% founding-level equity  Milestone bonuses tied to Day-60/90 deliverables. Change-of-control protection and refreshers at next financing. How we work Small, senior, high-trust team; short cycles, small diffs, preview-before-merge. AI-accelerated dev, measured by quality, safety, and cost—not just speed. Security by default and data privacy from day one. Process: Intro chat → Systems/product deep-dive → Practical pairing or time-boxed take-home (≤3 hours) → Founder loop → Offer.
