About the Role

We're looking for a passionate Backend Engineer to build and scale the backend systems that power our AI platform for engineering simulation. You'll work on production-grade APIs,distributed microservices, event-driven architectures, durable long-running workflows, and cloud-native infrastructure.

  • It's a new platform, built from the first commit. This role is ideal for engineers who enjoy solving
  • complex backend problems, building highly scalable systems, and taking ownership of services
  • from design to production. You'll collaborate closely with ML engineers, simulation engineers,
  • and platform engineers to build reliable backend services capable of handling high-throughput
  • AI and simulation workloads in a fast-paced startup environment.

What You'll Build

  • Production-grade REST and gRPC APIs using FastAPI
  • Distributed microservices powering AI and simulation workflows
  • Durable, long-running workflows using Temporal
  • Event-driven systems using Kafka or Pub/Sub
  • Scalable PostgreSQL data models, including vector search
  • Cloud-native, observable services on Kubernetes

Key Responsibilities

Backend Development

  • Design, develop, and maintain REST APIs (FastAPI) and gRPC services, contract-
  • first
  • Build modular, reusable, type-safe, and well-tested backend services
  • Design PostgreSQL schemas with proper indexing, constraints, and migrations, and
  • optimize queries
  • Build durable, long-running workflows using Temporal: workflows that run for hours,
  • wait for human input, and resume after failures
  • Build asynchronous processing using Kafka, Celery, Redis, or Airflow
  • Integrate backend services with storage such as GCS/S3 and internal platform
  • services

Distributed Systems

  • Build resilient systems with retries, dead-letter queues, idempotency, and failure
  • recovery
  • Design stateless, horizontally scalable services with both synchronous and
  • asynchronous communication
  • Keep each customer's data isolated at every layer of a multi-tenant platform

Platform & Cloud

  • Work with GCP services such as GKE, Cloud SQL, Cloud Storage, and Pub/Sub,
  • and with PostgreSQL run in our own containers on Kubernetes
  • Implement caching strategies using Redis

Reliability & Observability

  • Implement structured logging and instrument services with Prometheus and
  • OpenTelemetry.
  • Improve reliability through health checks, readiness probes, graceful shutdowns, and
  • fault tolerance.
  • Participate in production debugging, incident response, and performance optimization.

Required Skills

Backend Engineering

  • 4+ years of professional backend development experience
  • Strong Python skills, including async programming (async/await, concurrency,
  • background workers) with FastAPI
  • Experience with the modern Python service stack: Pydantic, SQLAlchemy (async),
  • Alembic, pytest, and mypy
  • Solid REST and gRPC API design, contract-first (OpenAPI, protobuf, JSON Schema)
  • Experience with PostgreSQL, database design, and query optimization; familiarity with vector databases such as pgvector
  • Good understanding of distributed systems and event-driven architectures, with
  • Kafka or Google Pub/Sub
  • Understanding of multi-tenant system design
  • Experience with Redis for caching, task queues, or rate limiting

Cloud & DevOps

  • Experience with Docker and deploying applications on Kubernetes (GKE preferred)
  • Familiarity with CI/CD pipelines (GitHub Actions preferred)
  • Understanding of rolling deployments, rollbacks, secrets management, and

configuration management.

Good to Have

  • Experience with Temporal or other workflow orchestration tools
  • Experience with engineering simulation or physics: CAE tools, CFD or thermal
  • analysis, solvers such as OpenFOAM or Ansys, or HPC
  • Experience with the transactional outbox pattern and change data capture
  • (Debezium)
  • Experience with MCP or LLM agent frameworks such as LangGraph
  • Experience with NoSQL and graph databases

What We're Looking For

  • We value engineers who:
  • Take ownership from design to production
  • Build scalable, reliable, observable, production-ready systems
  • Bring strong debugging, problem-solving, and system design skills
  • Make pragmatic engineering decisions with long-term maintainability in mind
  • Communicate clearly and work independently in a fast-moving startup
  • Are eager to learn new technologies and solve challenging backend problems

Why Join Us?

  • Build cutting-edge AI infrastructure on a new platform, from the first commit
  • Work on products that operate at scale
  • High ownership, minimal bureaucracy, and real influence on architecture
  • Collaborate with experienced Backend, ML, Platform, and Simulation Engineers
  • Continuous learning through mentorship and challenging engineering problems

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
