Software Engineer

Descripción del puesto

The role You'll build and own the backend systems Letly runs on — the software behind every viewing, tenancy, certificate, rent payment and repair. These are systems where correctness, reliability and scale are non-negotiable : real people's money, homes and legal exposure are on the line. This is one role hiring at every level, junior to staff — we level on the scope you own, not years served. At junior you ship features inside services others own, with review, mentoring and real production responsibility from the first month — the fastest engineers here ask early and close the loop quickest. At mid you own features and services end-to-end. At senior you own systems others build on — you make the architecture calls, set the patterns, and raise the bar around you. At staff you own the technical direction of a domain: you decide what gets built and how, you unblock other engineers, and you answer for how those systems behave under load. What you'll work on Money movement. Rent, deposits and payouts through pooled client-money accounts — idempotent processing, split-settlement, exactly-once across service and bank boundaries. Reconciliation & bookings. A penny-accurate, self-healing ledger reconciling bank activity across thousands of tenancies; contended scheduling — viewings, certs, photography, maintenance against finite slots and vendor availability. Event-driven consistency. Services coordinating over Pub/Sub — sagas across offer → contract → tenancy → payment with no distributed transaction to lean on. LLM tool calling, deterministic API calls, and other intra- and inter-service communications all running across the same coordination system. AI harnesses in production. Deploying agentic AI into real-world operational settings — acting on real money, tenancies and legal exposure, with the guardrails, observability and correctness that demands. Non-deterministic LLM working within compliant, secure deterministic software. Our stack We build on NestJS + TypeScr
