Founding Engineer

We’re partnering with an early-stage AI-driven startup building a next-generation personal project manager — an intelligent assistant on your smartphone that helps turn intent into action. Through simple micro-interactions, the system routes tasks to the right person or AI agent, and presents everything requiring your attention in one unified feed.

The company is a small, highly experienced team led by a deeply technical founder with a strong track record (three B2C products, $200M+ combined valuation, one successful exit).
Backed by $3M in pre-seed funding, the team is moving fast toward an MVP and preparing for public launch.

They’re now looking for a Founding Engineer — the main technical member of the team who will take full ownership of the backend and architecture. This is not a managerial role. The team is intentionally engineering-driven: they want someone who loves coding, thrives in hands-on work, and can design robust systems from scratch. Over time, the role will naturally expand into helping hire and shape the future technical team.

What you’ll do
- Own the backend: design domain models, service boundaries, and clean REST APIs for the iOS app.
- Build event-driven systems: queues/workers, retries, backoff, DLQs, idempotency, outbox/saga patterns.
- Design and build agentic systems: planners, tool‑using executors, reflection/critique loops, and multi‑agent workflows.
- Make data fly: PostgreSQL schemas, migrations, indexes; Redis for caching, locks.
- Ship production-grade reliability: observability (metrics/traces/logs), SLOs, on-call readiness, perf profiling.
- Harden security: secrets management, least-privilege, input/tenant isolation, safe PII handling.
- Level up DX: CI/CD, testing strategy, code reviews, docs, and ruthless simplicity in implementation.

Tech stack
- Node.js 24+, TypeScript 5.9.
- NestJS, Clean Architecture & DDD.
- PostgreSQL 17+, Redis 8+, BullMQ Pro.
- AI SDK. LLMs: OpenAI, Anthropic, Gemini.
- iOS 26, SwiftUI + SwiftData (client).

You’re a great fit if you
- Have strong experience with Node.js + TypeScript, and can write clean, maintainable NestJS code.
- Can design asynchronous, fault-tolerant workflows with queues, workers, and idempotency.
- Speak SQL fluently: indexing, locking, transactions, and performance.
- Care about API ergonomics and compatibility over time.
- Treat reliability, security, and observability as first-class features.
- Move fast with judgment and communicate crisply.
- Have high energy, an ownership mindset, and genuine enthusiasm for building.
- Actively use AI tools in your engineering workflow and embrace an AI-accelerated development style.

Nice to have
- AI experience (LLMs, agents, RAG/vectors).
- Product instincts and taste for simple, focused UX.
- Security/privacy by design; secrets, PII handling, and pragmatic compliance.
- Experience collaborating with iOS/SwiftUI teams.

Location
- London (preferred).
- Remote work format for exceptional candidates.
- Relocation support available.

Why join this company?
- Build a category-defining product from the ground up.
- Work alongside a strong, hands-on technical founder and a team of senior engineers.
- High ownership, zero bureaucracy, real influence on product and architecture.
- Competitive salary + meaningful equity.
