Join a forward-thinking engineering team building Syntrix Core, the engine powering intelligent customer simulation. As a Software Development Engineer II, you'll help shape a multi-tenant platform that runs high-volume, AI-driven conversations for enterprise applications including contact center validation, agent training, and model testing.
What You'll Do
- Design and maintain Python-based backend services that orchestrate AI agent workflows using frameworks like LangChain and LangGraph
- Build scalable, cloud-native microservices deployed on Kubernetes, emphasizing resilience and performance
- Develop and extend REST APIs using the Litestar framework with strong typing and Pydantic data models
- Implement conversation state management in Couchbase, applying optimistic concurrency control for consistency across distributed environments
- Integrate with third-party contact center platforms and large language model providers through unified gateway abstractions
- Write clean, testable code with a focus on behavior-driven testing at both unit and integration levels
- Collaborate with senior engineers to define system architecture and drive technical innovation
What We're Looking For
- Bachelor’s degree in Computer Science or a related field
- At least 4 years of professional software development experience
- Strong command of Python, including async programming, type hints, and modern tooling (uv, ruff, mypy)
- Proven experience building and deploying microservices and REST APIs in production environments
- Familiarity with NoSQL or document databases such as Couchbase, PostgreSQL, or Firestore
- Working knowledge of Kafka and event-driven architectures
- Experience with containerization using Docker and orchestration via Kubernetes
- Solid grasp of distributed systems concepts, including idempotency, stateless design, and concurrency control
- Proficiency with Git and CI/CD pipelines, preferably GitLab CI
- Demonstrated commitment to automated testing and code quality
- Strong problem-solving skills and a focus on delivering value to end users
Nice to Have
- Hands-on experience with AI/ML frameworks or LLM application development
- Exposure to LangChain, LangGraph, or similar agent orchestration tools
- Familiarity with Pydantic and Litestar (or FastAPI/Starlette)
- Experience integrating with LLM providers such as OpenAI, Anthropic, or Google VertexAI
