Agentic Lead Engineer (human)

About the Position

We are looking for an Agentic Lead Engineer to help shape the next generation of our platform. This is not a role for someone who wants to maintain a traditional Rails product all day. Rails is part of our system, but the center of gravity for this role is our new architecture: TypeScript services, durable workflows, event-driven payments infrastructure, agent-assisted engineering, and production systems where correctness matters.

You will lead from the front: designing systems, reviewing architecture, raising engineering quality, and using AI agents as a serious force multiplier rather than a novelty.

About the Role

You will help build and lead work across:

• Next.js 16, React 19, TypeScript frontend surfaces for creators, buyers, affiliates, and internal operations
• Bun/TypeScript services for payout, affiliate, webhook delivery, contact sync, event schemas, and service orchestration
• Restate durable workflows for money movement, idempotency, retries, and long-running business processes
• Hono, Drizzle, Postgres, Zod, AJV for typed service APIs and strict event contracts
• Supabase/PostgREST for community and gamification surfaces
• Stripe Connect payment and payout flows
• EventBridge/SQS/outbox patterns for reliable domain events
• OpenTelemetry and Aient for trace-driven debugging and production insight
• Playwright, Vitest, Docker Compose E2E stacks for high-confidence delivery
• Terraform/ECS/GitHub Actions for cloud infrastructure and deployment

Responsibilities

• Lead technical design for new platform capabilities across frontend, services, events, and infrastructure
• Own architecture for critical flows such as checkout, affiliate attribution, payouts, webhook delivery, and creator onboarding
• Review code and designs with a strong eye for correctness, observability, testability, and maintainability
• Guide engineers and AI agents through implementation plans, code review, test strategy, and production hardening
• Improve our engineering system: documentation, CI, E2E reliability, service boundaries, deployment safety, and observability
• Help migrate product capability from legacy CopeCart into the new COPE platform without dragging legacy assumptions forward
• Build a culture where types, tests, traces, and clear ownership are normal

Requirements

• Strong TypeScript experience across frontend and backend systems
• Deep practical experience with React/Next.js and modern frontend architecture
• Experience designing distributed systems with events, queues, retries, idempotency, and observability
• Comfort working on payments, ledger-like systems, payouts, compliance-heavy flows, or similarly high-correctness domains
• Strong testing instincts: unit, integration, contract, and E2E
• Ability to lead engineers through ambiguity without creating process theater
• Real interest in AI-assisted engineering and agentic workflows
• Pragmatic taste: you can move fast, but you know where shortcuts become debt
• Strong DevOps experience: CI/CD, Docker, cloud infrastructure, runtime configuration, deployment safety, observability, incident debugging, and production ownership
• Experience owning systems end-to-end, from design and implementation through deployment, monitoring, and operational support

Nice to Have

• Restate, Temporal, Durable Objects, or other durable execution systems
• Stripe Connect, marketplace payments, payout systems, tax, invoicing, or reconciliation experience
• OpenTelemetry, trace-based debugging, or production observability experience
• Supabase/PostgREST experience
• Terraform, ECS, Docker, and GitHub Actions experience
• Experience leading small high-output engineering teams

We Offer

• Remote & flexibility: Work from anywhere. Flexible working hours based on trust - no rigid schedules, but real ownership and autonomy.
• Room for impact: In your day-to-day work, you will face a variety of exciting challenges that allow for a high level of ownership. Got a creative idea or a suggestion for improvement? Feel free to share it. We are always open to innovation, new ideas, and thinking beyond the obvious.
• Benefits: Access to attractive corporate benefits as well as a company pension plan are naturally included.
• Company fitness: The health and well-being of our employees matter to us. Through our partner EGYM Wellpass, you get access to more than 6,300 fitness and yoga studios, swimming pools, as well as CrossFit and bouldering gyms across Germany and Austria.
• Team events: Remote does not mean isolated. Several times a year, we meet in different locations for real exchange, real team building, and real connection.
