It moves data through LLMs, transforms agent outputs into structured downstream data, runs jobs reliably, and keeps the system fast, cheap, and observable as we scale.\nBecause we're an early-stage company moving fast, we're looking for an engineer who can build the platform, keep it running, and make tradeoffs while priorities shift. This is an in-person role, 5 days a week in our office. The ability to balance reliability with iteration speed is essential.\nKey Responsibilities\nOwn the data platform: Maintain and evolve the platform that powers every job across the company.\n\nRun the LLM ETL pipeline: Ingestion, transformation, enrichment, and storage of LLM-driven data.\n\nBuild agent transformation infrastructure: The systems that take agent outputs and turn them into structured, queryable data downstream.\n\nImprove reliability, throughput, and cost of LLM-driven jobs in production.\n\nBuild observability and tooling so the team can debug and iterate quickly.\n\nPartner with AI Engineers: Expose new capabilities through the platform and shape the interfaces they build on.\n\nOperate the system: Participate in on-call rotation and incident response.\n\nWhat We Are Looking For\nStrong Python engineering experience supporting production systems (FastAPI or similar)\n\nExperience building or maintaining production pipelines that handle non-trivial volume, retries, backfills, and failure recovery\n\nHands-on experience with a data orchestrator (Dagster, Airflow, Prefect, or Temporal) and dbt or similar transformation tooling\n\nComfort with PostgreSQL at scale: schema design, multi-schema setups, and migrations\n\nComfort with AWS infrastructure (ECS, Lambda, SQS, Step Functions, RDS, S3) and IaC (Terraform / Terragrunt)\n\nFamiliarity with LLM APIs and the operational realities of LLM-based systems (latency, cost, retries, structured output, failure modes)\n\nNice to Have\nExperience with distributed compute for Python workloads: Anyscale Ray, Dask, or Spark\n\nExperience with Polars and Pandas for data processing\n\nFamiliarity with Datadog for observability, metrics, and tracing\n\nCost optimization experience for LLM workloads\n\nFamiliarity with pgvector or other vector stores\n\nMulti-region AWS deployment experience\n\nSome TypeScript/Node experience, since parts of the platform live there\n\nAbout Fluency\nFluency builds a platform that captures how work actually happens inside large organizations, measures productivity and process conformance, and analyzes where AI can do the work.\nWe capture observable work data across tools and systems, structure it into a model of how work runs, and use it to measure productivity, check process conformance, and analyze where AI changes the work.\nFluency is looking for a Software Engineer, AI Platform to build the data platform, LLM pipelines, and agent infrastructure that every AI feature at the company runs on, deployed across Fortune 500 organizations.\nOur Customers\nCustomers include CVS Health, Aon, and PVH.\nLocation\nFull-time, in-person role based in San Francisco, CA.\n\nWe offer E-3 sponsorship for Australians to relocate with stipend.\n\nThis role is not a fit if\nYou want hybrid or remote\n\nYou're not comfortable with rapid iteration\n\nYou haven't owned production systems\n\nYou've never operated production pipelines\n\nYou don't want to be on-call\n\nYou dislike constraints (we have them: cost, latency, reliability tradeoffs are real)\n\nRequirements need to be locked down before you can move\n\nHiring Process\nResume screen\n\n1:1 with founder\n\nTechnical deep-dive on past data platform or backend engineering work\n\nWork through a real problem with the team\n\nOffer\n\nWe strongly encourage applicants from underrepresented backgrounds to apply. Diverse teams build better products.\nCompensation & Benefits\nBase salary: US$180,000 to US$250,000\n\nESOP: Available\n\nUS$1,000 per month food and commuting allowance\n\nLaptop of choice","description_format":"text","description_chars":4152,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Machine Learning","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-09-06T08:17:29Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 6","filings_12m":6,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":97500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":2}],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.207,"p_room":0.28,"age_days":168,"expected_fill_days":28,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/fluency-software-engineer-ai-platform","json_url":"https://alion.io/job/fluency-software-engineer-ai-platform.json","meta":{"generated_at":"2026-10-31T21:35:44Z","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":33785,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":173608},"rest":"https://alion.io/mcp/rest/get_company?id=173608"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffluency-software-engineer-ai-platform"},{"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%2Ffluency-software-engineer-ai-platform"},{"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%2Ffluency-software-engineer-ai-platform"},{"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/fluency-software-engineer-ai-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffluency-software-engineer-ai-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":449644}},{"tool":"search_jobs","arguments":{"company":"usefluency.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":449644},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
