This is a backend-heavy role: distributed Python services, streaming LLM/agent runtimes on AWS, RAG pipelines, and the dbt/Airflow automation that powers our data products.\nResponsibilities\nDesign, build, and maintain backend services and APIs in Python - RESTful and streaming (SSE) endpoints, agent runtimes on AWS Bedrock AgentCore / ECS Fargate, and event-driven Lambda handlers.\nArchitect service boundaries and data flows: define contracts between services, model persistence, and manage state, caching, and asynchronous/background processing.\nBuild RAG pipelines and tool-calling AI agents over our data products: retrieval, orchestration, grounding, and evaluation.\nDesign data access and storage layers: schema/data modeling, query performance, connection/session management, and integration with warehouses (Snowflake) and key-value stores (DynamoDB).\nImplement auth and identity: OAuth/OIDC flows (per-user 3LO, token vaulting, session binding), least-privilege IAM, secrets management.\nBuild and maintain data-platform automation: dbt models, MWAA/Airflow orchestration, and tooling for discoverable, governed, consumable data products.\nOwn service reliability and delivery: Terraform, GitHub Actions CI/CD, container builds, structured logging, metrics/tracing, alerting, and cost controls.\nSet technical direction: system and API design, code review, and mentoring.\n\nRequired skills\nBackend engineering\n5+ years designing, building, and maintaining production backend services at scale. 10+ years if Lead level engineering candidate.\nExpert-level Python for server-side development; solid grasp of at least one web/async framework (e.g. aiohttp, FastAPI, Flask) and the WSGI/ASGI model.\n Service and API design: REST (and/or gRPC), request/response and streaming patterns, pagination, versioning, idempotency, and backward-compatible contracts.\n Data layer: SQL and data modeling, query optimization and indexing, transactions, connection pooling; experience with relational, warehouse (Snowflake), and NoSQL/key-value (DynamoDB) stores.\nServer-side patterns: caching strategies, background jobs/workers, queues and event-driven processing, rate limiting, retries/backoff, and timeouts.\nPerformance & reliability: profiling, load handling, latency/throughput trade-offs, graceful degradation, and designing for failure.\nObservability: structured logging, metrics, distributed tracing, and debugging live production issues.\n\nSoftware engineering fundamentals\n Object-oriented programming (required): encapsulation, abstraction, inheritance, composition, polymorphism; SOLID principles; design patterns applied pragmatically; strong domain modeling.\nSolid data structures & algorithms; ability to reason about time/space complexity.\n Concurrency and async programming (async/await, threading, event loops) and their failure modes.\n Testing (unit, integration, end-to-end) and testable design; Git and PR-based workflows; disciplined code review.\n\nCloud & infrastructure\nProduction AWS: ECS/containers, Lambda, IAM, API Gateway, DynamoDB.\nInfrastructure as code with Terraform; CI/CD (GitHub Actions or equivalent) and container builds.\n\nDistributed systems\nBuilding services that are horizontally scalable, resilient, and loosely coupled; handling consistency, retries, idempotency, and partial failure.\n\nSecurity\nOAuth/OIDC, authn/authz, token handling, least-privilege access, multi-tenant isolation, secrets management.\n\nAI / LLM engineering\nBuilding LLM applications in production (not research).\nRAG: chunking, embeddings, vector search, hybrid search, reranking, grounding/citations, context-window management, retrieval evaluation.\n Agents: prompt engineering, tool use/function calling, structured outputs, agent orchestration (single- and multi-step), prompt caching.\nIntegration with model providers - Anthropic/Claude, AWS Bedrock/AgentCore, Snowflake Cortex - and response streaming.\nAI quality & ops: eval harnesses, guardrails, tracing/observability, token/latency/cost optimization.\nAI security: prompt injection, data exfiltration, PII handling, per-user identity/RBAC enforcement.\n\nNice to have\ndbt, Airflow/MWAA, Snowflake.\n MCP (Model Context Protocol) and/or RAG\n Slack platform (Bolt, Socket Mode, Block Kit) or other real-time/conversational backends.\nFine-tuning/adaptation, semantic caching, or model routing/fallback.\nExperience adding AI capabilities to existing production systems.","description_format":"text","description_chars":4542,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-17T12:17:51Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.6,"p_room":1,"age_days":13,"expected_fill_days":73,"reasons":["conf:2","stale_co","win:early"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/relanto-lead-backend-engineer-data-engineering-ai","json_url":"https://alion.io/job/relanto-lead-backend-engineer-data-engineering-ai.json","meta":{"generated_at":"2026-10-20T15:50:19Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17971,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4442664},"rest":"https://alion.io/mcp/rest/get_company?id=4442664"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frelanto-lead-backend-engineer-data-engineering-ai"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Frelanto-lead-backend-engineer-data-engineering-ai"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Frelanto-lead-backend-engineer-data-engineering-ai"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/relanto-lead-backend-engineer-data-engineering-ai\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frelanto-lead-backend-engineer-data-engineering-ai"}]}
