Ready to reshape one of the world’s largest industries? nPlan has built a unique AI platform that helps some of the largest construction companies understand, manage, and reduce the risk in some of the world’s largest impactful construction projects. Join our Product Engineering team to design, implement, and ship high-impact AI solutions that help the world build better.
The backend team owns the systems that power our platform. You will design, implement, and build new capabilities that are performant, dependable, and extensible. These capabilities range from basic CRUD and APIs to cutting‑edge Agentic AI systems powered by a wide range of frontier AI models.
What you’ll do
- Design, build, and deploy new backend capabilities: our customers are always asking for more, and especially more sophisticated AI systems.
- Lead technical delivery: propose designs, evaluate trade‑offs, drive changes from design to deployment.
- Improve operations: observability, incident response, performance, scaling, automation.
Our stack
- Languages: Python, Go, Typescript
- APIs: GQL, gRPC, REST
- Databases: Postgresql, Vector DBs, BigQuery, blob storage
- Async: Vertex AI, GCP pub/sub
- Deployment: GCP, Kubernetes, ArgoCD, Github Actions
- Operations: Prometheus, Grafana, Sentry
What we’re looking for
- Startup mentality: we are changing the world, and what is required can be ambiguous yet we need to deliver fast and reliably.
- Experience of production systems: at least 3 years of experience building scalable production systems.
- Experience using Kubernetes in a cloud environment.
- Solid system design fundamentals: you know how to design a reliable, testable and scalable system from scratch.
- Strong SQL: data models, indexing, production‑level migrations, performance scaling.
- A testing mindset: we always strive to be better at this so would be particularly keen who brings this to the team.
- Practical security awareness: you understand attack surfaces, common vulnerabilities.
- Using the latest technologies to iterate fast: using coding agents and similar technologies to get stuff done fast.
- Strong code review habits: This skill is an important quality gate for pushing to production.
You might be our person if you…
- Build reliable backend systems: You’ve designed, shipped, and operated production services and APIs that real users depend on.
- Think in distributed systems: You’re comfortable with queues, retries, idempotency, consistency trade‑offs, and failure modes.
- Care about operability: You set a high bar for observability (logs/metrics/traces), on‑call readiness, incident response, and performance tuning.
- Model and work with data: You write strong SQL and understand indexing, migrations, data modelling, and referential integrity.
- Code with confidence: You build clean, well‑tested services (unit/integration tests) and can work effectively in a modern backend stack (e.g., Python, Go, Typescript).
- Thrive in autonomy: You enjoy taking ambiguous problems, clarifying requirements, and driving work to a shippable solution.
