Apiphani is building the future of intelligent infrastructure automation through agentic AI. They are looking for a Senior Backend Engineer to help design and build the systems that power Luumen — an AI-driven automation platform used by enterprise IT and managed service providers around the world. This is a high-impact, zero-to-one engineering role focused on building the backend foundations for large-scale AI orchestration.
Requirements
- Strong proficiency in Python and TypeScript for building distributed, event-driven systems
- Deep understanding of AWS services (Lambda, ECS, Bedrock, S3, CloudWatch, etc.)
- Experience designing APIs, microservices, and event pipelines that interface with LLMs or AI models
- Familiarity with vector databases and concepts like embeddings, similarity search, and retrieval-augmented generation
- Experience with infrastructure-as-code tools such as Terraform or AWS CDK
- Understanding of SQL and schema migration workflows (PostgreSQL or similar)
- Hands-on experience with Docker, GitHub Actions, and cloud-native CI/CD workflows
Responsibilities
- Design and implement backend services that enable intelligent agent workflows and autonomous infrastructure actions
- Develop APIs and orchestration layers in Python and TypeScript, integrating LLMs, vector databases, and observability pipelines
- Build scalable systems to support LLM-based reasoning, retrieval, and decision-making across cloud infrastructure
- Integrate with AWS Bedrock and other LLM platforms to support multi-model capabilities
- Develop data access and semantic search layers using vector databases (e.g., pgvector, Pinecone, Qdrant)
- Build robust monitoring, testing, and CI/CD systems to ensure reliability and reproducibility of AI workflows
- Collaborate closely with the product and DevOps teams to design architecture diagrams, plan deployments, and monitor system health
Other
- 6+ years of backend engineering experience in production environments
- Ability to diagram systems, communicate architecture decisions clearly, and work asynchronously in a distributed team
- Strong sense of ownership and ability to deliver in fast-moving, ambiguous environments
- Experience working with LangChain, OpenAI, or Anthropic APIs
- Familiarity with agentic frameworks or AI orchestration systems
