About Aedeon
Aedeon is the agent-native modernization platform for the enterprise. We turn the systems already running the business, applications, databases, data platforms, business rules, and workflows, into governed AI agents, grounded in a persistent Code Intelligence Graph of the customer's own code and verified through behavior-equivalence proof. Aedeon is delivered as a product, not a services engagement, and runs without mandatory forward-deployed engineers.
As Senior Product Engineer on Aedeon's Agent Systems team, you'll build the agents that do the actual modernization work. Aedeon's product surface is the agent fleet itself: parsers that read legacy estates, extractors that lift business rules out of code, synthesizers that stand up agentic workflows, verifiers that produce behavior-equivalence proof. You'll design and ship those agents.
Aedeon is product-led, not services-led. The agents you build are the product. They run against the Code Intelligence Graph, a persistent semantic representation of the customer's estate, and operate under governed autonomy with shadow, supervised, and autonomous stages. You'll write Python every day, orchestrate frontier foundation models through the Aedeon Decision Model, and ship into the same release discipline the rest of the product team holds.
This role does not require prior Bedrock or LangChain experience. It requires a strong Python engineer who treats agent frameworks as something to learn deeply, not a buzzword. Aedeon is technically demanding, with real enterprise customers in regulated industries and audit chains that must stay intact. We're looking for someone who writes Python they'd be proud to read in a year, treats test cases as a first-class deliverable, and uses AI tools to do the job better and faster.
What will you do?
Agent Systems Development
- Build and ship specialized agents in the Aedeon fleet: parsers, business-rule extractors, dependency mappers, test synthesizers, behavior replayers, and the orchestration that wires them together.
- Design agents that operate against the Code Intelligence Graph rather than generating from priors, so every agent action traces to a line of code.
- Implement governed autonomy: shadow, supervised, and autonomous stages with human-in-the-loop controls at every stage.
- Orchestrate frontier foundation models (Anthropic, OpenAI, Google) through the Aedeon Decision Model: pick the right model for each task, against the right slice of the graph, under explicit governance constraints.
Release Ownership
- Own the full delivery of assigned agents from prototype through deployment and post-release validation.
- Commit to sprint and release deadlines. Raise blockers and risks with enough lead time to mitigate them.
- Coordinate with platform and DevOps engineers to keep deployment pipelines clean and repeatable.
Verification and Quality
- Practice test-driven development. Write the tests for the agent's contract, governance constraints, and equivalence checks before the agent code that satisfies them.
- Build behavior-equivalence verification into every agent: dual-run tests, output diffing, equivalence certificates against production traffic.
- Write detailed test cases before deployment, covering functional flows, edge cases, regression scenarios, and integration touchpoints.
- Use AI tools to generate qualitative test coverage at scale and validate it for completeness.
- Maintain automated test suites (unit, integration, E2E) and integrate them into the CI/CD pipeline.
Collaboration and Documentation
- Write clear, maintainable Python with adequate documentation. Review pull requests thoroughly and provide constructive feedback.
- Document agent contracts, prompt structures, decision logic, and verification approaches in Confluence or equivalent.
- Share patterns and testing practices across the team. Promote a culture of release discipline and quality.
What are we looking for?
Core Python and Systems
- Strong Python (4+ years production), async (asyncio), performance optimization, idiomatic code.
- Solid grasp of distributed systems concepts: state machines, retries, idempotency, eventual consistency.
- Experience integrating with LLM APIs (Anthropic, OpenAI, or similar) from production code: streaming, function calling, structured output, retries, prompt management.
- Comfort with FastAPI or equivalent async web frameworks.
Cloud and Infrastructure
- Working knowledge of AWS services: EKS, ECS Fargate, S3, DynamoDB, Lambda, Secrets Manager, CloudWatch.
- Experience with Docker and Kubernetes: writing Dockerfiles, Helm charts, and Kubernetes manifests.
- Comfort with CI/CD pipelines, GitHub Actions preferred.
- Comfort navigating multi-account AWS environments (dev, uat, prod).
Testing and Automation
- Test-driven development as a discipline. Tests written before the code, not after.
- Hands-on experience with pytest, integration testing, and E2E testing.
- Ability to design behavior-verification harnesses: dual-run, output comparison, equivalence proof.
- Experience using AI tools (Claude, Copilot, LLM-based test generators) to accelerate and improve test case quality.
- Experience integrating automated tests into CI/CD pipelines.
Engineering Mindset
- Test-first, release-disciplined, ownership-driven.
- Strong written and spoken English. You'll be in product reviews and customer-impacting design discussions.
- Available to work with US business-hour overlap from India.
You'll be preferred if
- Agentic AI frameworks: AWS Bedrock AgentCore, Strands SDK, LangChain, or similar.
- Temporal.io or other workflow orchestration engines.
- Graph databases (Neo4j) and Cypher query language.
- Amazon OpenSearch Service or Elasticsearch.
- Java exposure for working with the Java Analyzer component.
- Prior B2B SaaS product work with a structured release process.
- Domain exposure to enterprise modernization: mainframe, SAP, Oracle, or large Java / .NET estates.
