Role Summary / Purpose
We are looking for a hands-on Principal Engineer / Tech Lead who can both build and guide the build of production-grade agentic AI applications on AWS — primarily on the AWS Strands SDK and Bedrock AgentCore — and who treats agents as real software systems, not prompt experiments. This person owns the engineering quality bar for 1–2 delivery teams: design patterns, Python craft, testing, evals, CI/CD, observability, and on-call readiness. They write code roughly 60% of the time and lead/review/mentor the rest.
They consume the primitives defined by the AI Platform / Cloud Solution Architect (model gateway, MCP/tool registry, memory store, eval harness, guardrails, identity, kill switch) rather than rebuilding them, and hold their teams to that same discipline.
Key Responsibilities
Build (hands-on, ~60%)
- Design and implement end-to-end agents on AWS Strands SDK and Bedrock AgentCore, including tool orchestration, multi-step reasoning, memory, HITL gates, and structured streaming. Use CrewAI or LangChain/LangGraph only where Strands does not fit, with explicit justification.
- Write clean, idiomatic, testable Python: typed (mypy/pyright), modular, async-aware, with strong package boundaries. Follow SOLID and apply the right design pattern for the job (Strategy, Adapter, Repository, Factory, Mediator, Circuit Breaker, Saga) — and apply the right agentic pattern (ReAct, Plan-and-Execute, Reflection, Router, Hierarchical Multi-Agent, Tool-Use, RAG-Fusion) deliberately rather than by default.
- Build agent backends as proper services (FastAPI), with clear domain models, dependency injection, hexagonal/ports-and-adapters separation between LLM/tool calls and business logic, and contract tests against platform APIs and MCP tools.
- Implement RAG correctly: chunking strategy, embedding choice, hybrid retrieval, grounding/citations, and eval-driven iteration. Use only platform-provided vector stores and follow data-classification and residency rules.
- Integrate with the model gateway, MCP/tool registry, identity (OIDC/OAuth2/SCIM), and observability SDK rather than calling model APIs or building auth/logging directly.
Lead and guide (~40%)
- Set and enforce the engineering bar across 1–2 agile teams: code reviews, design reviews, ADR (architecture decision record) discipline, definition of done, and PR standards. Block merges that skip evals, observability, or guardrails.
- Decompose roadmap items into well-shaped backlogs; pair-program with mid/junior engineers; mentor on Python, cloud, and agentic concepts; grow the next tech leads.
- Own the team's technical roadmap in partnership with PM and the AI Platform architects; identify reusable primitives and push them upstream into the platform instead of forking.
- Drive incident response for agent workflows: triage, RCA, postmortems, and reliability follow-ups. Carry primary on-call rotation alongside the team.
- Write designs, runbooks, and ADRs that both engineers and non-technical stakeholders can read.
DevOps / LLMOps
- Own CI/CD for agent services end-to-end (Jenkins or GitHub Actions): unit + integration + contract tests, SAST/secret scanning, image build, IaC plan/apply, and gated promotions across dev/QA/prod AWS accounts.
- Treat evals as a first-class CI gate: golden datasets, rule-based and LLM-as-judge scoring, replay harness for deterministic reproduction of production sessions, and regression checks on every model or prompt change.
- Instrument every agent through the platform observability SDK: structured logs, OTEL traces with token/cost stamping, per-tool spans, and dashboards in CloudWatch / Splunk / New Relic. Define and meet SLOs (p95 latency, success rate, RAG groundedness).
- Run online evals and drift detection on production traffic; wire kill-switch and cost circuit breakers; respond to guardrail and content-safety incidents.
- Contribute Terraform/CDK modules for agent services and follow least-privilege IAM, private networking, and secrets-via-vault patterns by default.
Required Skills/Knowledge
- Bachelor's degree in Computer Science / Engineering or equivalent practical experience.
- 8+ years of software engineering experience, with 3+ years as a tech lead / staff / principal engineer on cloud-based production systems.
- Expert-level Python: typing, async, packaging, testing (PyTest, hypothesis), API design (FastAPI), and clean architecture. Able to read and improve a teammate's code on sight.
- Demonstrated mastery of software design patterns and the judgment to know when *not* to use them. Comfortable leading design reviews and ADR discussions.
- Hands-on experience building agentic / LLM applications in production or advanced pilots, including tool use, multi-step reasoning, memory, and HITL.
- Working knowledge of AWS Strands SDK and/or Bedrock AgentCore SDK, plus core AWS services (Bedrock, IAM, VPC/networking, S3, ECR/EKS or ECS, Secrets Manager, CloudWatch).
- Solid RAG fundamentals: embeddings, vector stores, hybrid retrieval, grounding, eval-driven iteration.
- Strong DevOps / LLMOps: CI/CD pipelines, IaC (Terraform or CDK), containerization, observability (logs/traces/metrics), and incident response. Has carried on-call.
- Experience integrating through API / model / MCP gateways with proper authn/z, rate limiting, retries, idempotency, and error semantics.
- Track record of mentoring and raising the bar for a team — not just shipping personal code.
- Strong written and verbal communication across engineering, product, security, and risk audiences.
Desired Skills/Knowledge
- Production experience with CrewAI and/or LangChain / LangGraph for cases that fall outside Strands.
- Multi-model fluency (AWS Nova, Anthropic Claude, OpenAI, Gemini) and pragmatic routing / cost-optimization strategies (cheap-first, cascade, semantic cache).
- Familiarity with agentic protocols (MCP, A2A, ACP, AP2) and multi-agent collaboration patterns.
- Front-end integration experience (React or similar) for streaming agent UX, chat surfaces, and HITL approval flows.
- Custom AI observability: agent-quality metrics, safety/guardrail telemetry, RAG groundedness scoring.
- Financial services or other regulated-industry experience (PCI / SOX / GLBA / SR-11-7 / NIST AI RMF awareness).
- Open-source contributions, conference talks, or technical writing in the agentic AI space.
Eligibility Criteria: Minimum 8+Years of experience mentioned in “ Required Skill/Knowledge” with a Bachelor’s Degree or equivalent. In Lieu
of degree , minimum of 10 years of experience required.
