We're at an exciting inflection point.\nWhile we've found real commercial success, our ambitions are larger: to become the go-to AI platform for all enterprise automation, powered by our voice superintelligence. The work affects millions of people every day, and our team has the autonomy to make true impact - with brilliant founders, a clear path forward, and the kind of momentum that defines generational companies.\nIf being part of that resonates with you, we'd love to hear from you!\nVoice AI startup Giga raises $61M Series A\n\nDoorDash and Giga Partnership\n\nThe Role\nWe're looking for backend engineers to build the infrastructure and systems that power our AI agents. You'll work across the stack, from data pipelines and analytics to real-time agent systems, shipping features that directly impact how our customers operate.\nThis isn't a role where you'll be handed a spec and asked to execute. You'll own problems end-to-end: figuring out the right approach, building it, and iterating based on what you learn.\nWhat You'll Work On\nA few examples from our current roadmap:\nAnalytics rewrite: Migrating our analytics service to ClickHouse and rebuilding it to scale through our next 10x of growth\n\nHallucination detection: Improving our detection systems with the goal of driving hallucination rates toward zero\n\nBrowser use agent: Scaling, stabilizing, and adding features and accuracy to our browser use agent in lieu of formal customer APIs\n\nAs a senior engineer, you'll be expected to make sound technical decisions, ship reliably, and help set the bar for code quality and system design. You'll have significant autonomy and influence over what gets built and how.\nTech Stack\nBackend: Python (Django/FastAPI), TypeScript (Node.js)\n\nInfrastructure: AWS, Modal, Kubernetes, Postgres\n\nFrontend: TypeScript, Next.js (you'll interact with this, but it's not the focus)\n\nYou Might Be a Fit If You\nHave 4+ years building backend systems, ideally at companies where reliability and scale mattered\n\nAre comfortable with ambiguity: you can take a loosely-defined problem and figure out what to build\n\nYou'll jump into unfamiliar parts of the codebase when that's what the problem requires\n\nWrite clean code and care about getting the details right, but also know when to ship\n\nWant to work on hard problems with a small team where your work has obvious impact\n\nAre excited about AI agents and the infrastructure challenges that come with running them in production\n\nPerks & Benefits\nCompetitive base + bonus + equity\n\nCatered lunch daily\n\nDinner stipend\n\n$500/month wellness & commuter benefit (gym, fitness classes, mental health)\n\n401(k) plan\n\nMedical, dental, and vision coverage\n\nGiga is an equal opportunity employer. We're committed to providing equal employment opportunities regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other characteristic protected by law.","description_format":"text","description_chars":3439,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Conversational AI","Speech & Audio AI","Contact Center Software"],"lifecycle":[{"event":"open","at":"2026-02-20T17:00:28Z"},{"event":"open","at":"2026-09-26T08:44:10Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 4","filings_12m":4,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":152500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":2}],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.194,"p_room":0.28,"age_days":238,"expected_fill_days":28,"reasons":["conf:3","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/giga-ai-senior-backend-engineer","json_url":"https://alion.io/job/giga-ai-senior-backend-engineer.json","meta":{"generated_at":"2026-10-18T10:44:24Z","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":15941,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":21351},"rest":"https://alion.io/mcp/rest/get_company?id=21351"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgiga-ai-senior-backend-engineer"},{"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%2Fgiga-ai-senior-backend-engineer"},{"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%2Fgiga-ai-senior-backend-engineer"},{"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/giga-ai-senior-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgiga-ai-senior-backend-engineer"}]}
