Job Description
Senior Backend Engineer – Automation, Platform Implementation
Assembly Industries
• Build, extend, and optimize Java-based microservices responsible for task execution, state management, and orchestration logic. • Model and manage NoSQL document databases to track execution state, workflow metadata, and session/context persistence. • Define internal API contracts, adapters, and connectors that enable modular integration with external APIs and customer deployments. • Implement production-ready infrastructure for data ingestion, document chunking, embedding indexing, and retrieval (RAG) pipelines. • Architect backend services that support multi-step agentic flows, including context assembly, tool calls, and session memory. • Turn product requirements for semantic search and AI assistant features into resilient, production-grade backend code. • Deploy, configure, and customize the automation platform to meet specific customer use cases and business requirements.
Job Requirements
- 4–6 years of software engineering experience building resilient production backend systems and working with distributed architectures.
- Strong proficiency in Java, with deep experience developing scalable microservices, handling asynchronous jobs, retries, idempotency, and system failure modes.
- Experience with NoSQL document databases (e.g., MongoDB, Firestore, Couchbase) for state and metadata tracking.
- Working knowledge of Python for building integrations, tooling, and rapid prototyping.
- Solid understanding of LLM application structures, including embedding systems, vector search, retrieval mechanics, context windows, and agent/tool execution.
- Proven ability to interface with product teams, solution architects, and customer stakeholders to translate vague user requirements into working, deployed software.
- A consistent habit of writing clear system designs and deployment guides so that the next team member never has to start from zero.
