The Role

As our Senior Backend Engineer, you’ll design and build the backend infrastructure that supports high-throughput, reliable, and secure AI agent workflows. You’ll work cross-functionally with ML engineers and data scientists to operationalize models at scale.

Key Responsibilities

  • Architect and implement scalable APIs, microservices, and event-driven systems to power ML pipelines and agent orchestration
  • Design efficient data modeling, ETL, and persistent storage suited for high-volume, real-time agent data
  • Optimize backend performance and ensure system stability under heavy concurrent load
  • Collaborate closely with founders and ML teams to deliver end-to-end agent features
  • Establish CI/CD pipelines, monitoring frameworks, and enforce backend security best practices
  • Mentor junior engineers and contribute to team culture and best practices

Requirements

  • 5+ years designing, implementing, and maintaining backend systems in Python
  • Experience building distributed, scalable services with microservices or serverless architectures
  • Strong grasp of relational and NoSQL databases, message queues (e.g., Kafka), and ETL patterns
  • Proven track record in API design (REST/gRPC), authentication, and reliable asynchronous processing
  • Familiarity with containerization (Docker, Kubernetes) and observability tools (Prometheus, Grafana)

Nice to Haves

  • Prior experience launching AI products or backend systems for ML/agent-driven applications
  • Knowledge of LLM APIs, prompt pipelines, and agent orchestration
  • Familiarity with cloud-native tools (AWS Lambda, S3, DynamoDB, GCP/Azure equivalents)
  • Experience in startup or early-stage environments

Why You Should Join

  • Competitive equity & pay - get in early and own what you build.
  • Work closely with experienced founders with a proven startup track record.
  • Move fast, ship fast - no corporate bureaucracy.
  • Shape the AI revolution in healthcare - massive market, untapped potential
