Backed by leading investors and 2,000+ customers, we exist to give sales teams an unfair advantage: the deepest company and people data of any platform, enriched with real-time signals, served at the right moment by intelligent agents.\nThe backend services, APIs, and AI systems behind every Firmable product are the engine room. This role owns it.\nThe RoleAs Software Engineering Lead, you'll own the function that designs, builds, and operates the backend services, RESTful APIs, and AI/LLM systems powering every Firmable product. You'll lead two engineering pods through their team leads while staying deeply hands-on yourself. Reporting to the Head of Data & Services.\nThis is not a people-management seat. ~80% hands-on architecture and engineering, ~20% leading the function. You whiteboard the system, write the reference implementation, then raise the whole team to that bar. If you want to step away from the code, this isn't it.\nWhat You'll Own\nBackend and API architecture — Firmable's Python services (FastAPI, Pydantic, Logfire): the secure, well-documented backbone every product, internal agent, and external customer depends on\n\nData modelling — schemas, access patterns, and integrity at scale across PostgreSQL, Snowflake, and DynamoDB\n\nAI/LLM services and agents — production systems that are fast, idempotent, observable, and cost-bounded; every LLM call a named, versioned tool with prompts, schemas, traces, and evals\n\nHarness engineering — the agent runtime the team builds on: tool-calling and MCP server layers, structured-output validation, bounded agentic loops, sandboxed execution, human-in-the-loop checkpoints, replayable traces\n\nEval harnesses — scorers, labelled sets, trajectory and multi-turn evals, LLM-as-judge calibration, regression suites in CI, drift detection on vendor model updates\n\nScale and reliability — systems serving millions of API calls: idempotency, caching, rate limits, cost ceilings, circuit breakers, bounded retries, graceful degradation\n\nObservability standard — structured traces, p50/p95/p99 by stage, cost per request, and the dashboards that make it legible\n\nFunction leadership — lead and grow two pods through their leads; run architecture and code reviews; set the bar for quality, testing, and AI-native practice\n\nCross-functional glue — connect Data Platform, Application, and Product; turn early ideas into architecture decisions and working prototypes fast\n\nWhat We're Looking ForMust Haves\n7-10 years hands-on backend engineering, including time leading engineers or engineering leads with 3+ years of hands on experience with Python.\n\nBuilt and operated large-scale production systems — millions of API calls, and you know what breaks first when load grows\n\nExpert Python with deep production experience in FastAPI\n\nShipped AI/LLM services, APIs, and agents in production — and stood up the evals that keep them trustworthy\n\nHarness engineering experience — you've built the scaffolding agents run inside: tool-calling frameworks, MCP servers, eval and test harnesses other engineers depend on, and you can walk us through it in detail\n\nHands-on data modelling across SQL and NoSQL\n\nDesigned and consumed RESTful services at scale\n\nShipped real work with agentic IDEs — Claude Code, Cursor, or equivalent. Not \"tried it\" — your default mode\n\nLead from the front — whiteboard to reference implementation to a team operating at that standard\n\nHighly Valued\nEval frameworks (Braintrust, Inspect AI, Promptfoo) and tracing stacks (Logfire, OpenTelemetry)\n\nAgent frameworks and protocols — Claude Agent SDK, Pydantic AI, LangGraph, MCP\n\nAWS and/or GCP at scale — ECS/Fargate, Lambda, S3, RDS, DynamoDB\n\nB2B data, entity resolution, or high-throughput enrichment pipelines\n\nSnowflake and modern data-platform tooling\n\nStartup or scaleup experience where you shipped fast and owned outcomes end to end\n\nHow We BuildFirmable is an AI-native organisation. Agentic development, AI-driven test generation, automated review pipelines, and built-in evals and traces are the default mode of working, not a productivity experiment. Recurring workflows ship as versioned SKILL.md specs any teammate or agent can run.\nWe run lean and ship fast — small senior teams, no layers, minimal process, weekly releases moving toward daily. Teams own their stack end to end. You need to be working this way already, and able to bring a team with you.\nWhy This Role\nOwn the engine room — you're not joining a team, you're leading the function\n\nArchitectural latitude — the next generation of our services and AI platform is yours to shape\n\nHands-on leadership — the influence of a lead with the satisfaction of still building\n\nMassive leverage — your work reaches every Firmable customer, every day\n\nCompetitive base + meaningful equity — a share in the upside we're building toward\n\nFirmable is an equal opportunity employer. We believe diverse teams build better products.\nOriginally posted on Himalayas","description_format":"text","description_chars":5080,"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":["Equity"],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales Enablement","Lead Generation","Marketing & Sales AI"],"lifecycle":[{"event":"open","at":"2026-10-26T19:11:04Z"}],"visa":[],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.8,"p_room":0.9,"age_days":17,"expected_fill_days":30,"reasons":["seen:17","win:mid"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/firmable-software-engineering-lead-data-services","json_url":"https://alion.io/job/firmable-software-engineering-lead-data-services.json","meta":{"generated_at":"2026-10-28T10:19:00Z","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":13563,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":14688},"rest":"https://alion.io/mcp/rest/get_company?id=14688"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffirmable-software-engineering-lead-data-services"},{"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%2Ffirmable-software-engineering-lead-data-services"},{"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%2Ffirmable-software-engineering-lead-data-services"},{"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/firmable-software-engineering-lead-data-services\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffirmable-software-engineering-lead-data-services"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3289618}},{"tool":"search_jobs","arguments":{"company":"firmable.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3289618},"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.
