Our API is designed from the ground up to power Retrieval-Augmented Generation (RAG) and real-time reasoning in AI systems. By connecting LLMs to high-quality, trustworthy web content, we help developers build agents that are not only intelligent - but also informed. \nWe work with some of the most innovative teams in AI - from small startups shaping the ecosystem to the largest enterprises deploying AI at scale. Whether it's powering sales assistants, research copilots, or internal knowledge tools, we're the missing link between LLMs and the real world. \nThe Role\nWe are looking for a Senior Full Stack Engineer to build how developers and AI agents access our agentic web infrastructure. This role is based in our New York office, hybrid with the NYC team.\nOur APIs are used by millions of developers and the AI agents acting on their behalf. The team owns the main API gateway, the customer platform (keys, usage, teams), identity and enterprise SSO, and the public interfaces to our product: the SDKs, CLI, MCPservers and other tools developers and agents use. You'll work closely with product, design and engineers across our R&D.\nIn this position, your responsibility will be to:\nDesign and ship features end to end, from the interface to the services and data behind it\n\nBuild and improve the API gateway: high traffic, low latency, reliable\n\nTurn usage, billing and team data into fast, usable interfaces: tables, charts, filters and forms\n\nShape the self-serve journey from signup through activation\n\nBuild and operate identity and team access in production: OAuth and OIDC, role-based access, SAMLSSOand SCIM, on providers such as Auth0, Okta, WorkOS or Clerk\n\nControl who gets which features, with feature flags for staged rollouts and entitlements after rollout\n\nImprove the public interfaces developers and agents use: the SDKs, CLI, MCPservers and docs\n\nYou may be a good fit if you:\nHave 5+ years of full-stack engineering on customer-facing products or high-throughput APIs, in any mix of frontend and backend\n\nAre strong in backend engineering, ideally in Python. Go, C++ or C with some Python experience also fits\n\nHave built and operated latency-sensitive, high-QPSAPIs: caching, async work, queues, retries and rate limiting, including long-running jobs and webhooks\n\nHave shipped production UI with a modern frontend framework such as React, Next.js or TanStack, ideally in TypeScript\n\nHave built data-heavy interfaces such as tables, charts and filters that stay fast\n\nAre effective in a mature, user-facing system: you have joined a complex codebase, ramped up fast, shipped safely under real traffic, and been on-call for it\n\nHave strong product and design sense, for interfaces and for APIs\n\nSee your work through from design to production, explain trade-offs clearly to partners, navigate ambiguity, and use AI tools in how you build\n\nStrong candidates may also:\nHave led a project or mentored others\n\nHave taken a product from 0 to launch\n\nHave built API-key issuance and lifecycle\n\nHave built MCPservers or tools for AI agents\n\nHave worked on billing or usage metering with Stripe, Metronome, Orb or similar\n\nWhy Tavily? \nFull ownership - small team, you own the entire infrastructure, not a slice of it \nReal scaling challenges - bursty scraping workloads, cache invalidation, multi-region, millions of daily requests \nAI-native company - your infra directly powers AI agents used by leading companies in the space. \nKey employee benefits in the US: \nHealth insurance: 100% company-paid medical, dental, and vision coverage for employees and families. \n 401(k) plan: Up to 4% company match with immediate vesting. \nParental leave: 20 weeks paid for primary caregivers, 12 weeks for secondary caregivers. \nRemote work reimbursement: Up to $85/month for mobile and internet. \nDisability & life insurance: Company-paid short-term, long-term and life insurance coverage. \nPay Transparency\nWe offer competitive compensation and benefits packages. Actual compensation will be determined based on job-related factors, including experience, skills, qualifications, the level at which the candidate is hired, and geographic location, consistent with applicable law.\nBase Compensation Range\n$147,200—$224,300 USD","description_format":"text","description_chars":4328,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Health insurance","Insurance coverage","Life insurance","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","AI Search"],"lifecycle":[{"event":"open","at":"2026-11-03T21:49:11Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":62,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":224300,"is_top_pay":true},"html_url":"https://alion.io/job/tavily-senior-full-stack-engineer-agentic-search-platform","json_url":"https://alion.io/job/tavily-senior-full-stack-engineer-agentic-search-platform.json","meta":{"generated_at":"2026-11-06T09:21:32Z","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":16919,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":6397},"rest":"https://alion.io/mcp/rest/get_company?id=6397"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftavily-senior-full-stack-engineer-agentic-search-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%2Ftavily-senior-full-stack-engineer-agentic-search-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%2Ftavily-senior-full-stack-engineer-agentic-search-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/tavily-senior-full-stack-engineer-agentic-search-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftavily-senior-full-stack-engineer-agentic-search-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3707792}},{"tool":"search_jobs","arguments":{"company":"tavily.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3707792},"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.
