Senior Back End Engineer

Senior Backend Engineer: Python & Java Microservices (AI Platforms)

Remote · Full-time · Exclusive

AllysAI builds production AI systems for regulated enterprises (banking, pharma, energy). You’ll build the backend those AI agents run on, integrated into our clients’ own systems.

What you’ll do

• Design and build microservices in Python (FastAPI) and Java (Spring Boot), including services deployed inside a client’s existing Java platform.
• Build the shared platform layer: API gateway integration, session and state handling, document services, and the tools our AI agents call.
• Integrate with enterprise systems through REST APIs and message queues: authentication (OAuth2, JWT), retries, idempotent writes, error handling and audit logging.
• Package and ship services as Docker images on Kubernetes (Azure AKS), with CI/CD, tests and monitoring.
• Work with our AI engineer, solution architect and DevOps engineer, and join client technical sessions when needed.

Must have

• 5+ years of backend engineering, with Java/Spring Boot and Python both used in production.
• Microservices you designed and own in production: APIs, databases (PostgreSQL), caching (Redis), queues (Kafka, RabbitMQ or Azure Service Bus).
• Solid grounding in security and reliability: auth, secrets, rate limits, retries without duplicate writes, observability.
• Docker and Kubernetes, CI/CD (GitHub Actions or Azure DevOps).
• Clear spoken and written English

Nice to have

• Banking, fintech or other regulated-industry systems.
• Azure (AKS, Service Bus, Key Vault, API Management) and API gateways such as Kong.
• Experience exposing services to AI agents (tool calling, MCP).
