We design AI agents that operate across the full sales action set, from account strategy to prospect research and outreach. Building 0→1 has never been easier, but selling at the speed of the market remains the last frontier for AI. Our mission is to 10x every seller by automating the busywork so they can focus on what humans do best: closing deals.\nToday, over 1,500 customers run on Nooks, including Notion, HubSpot, Cursor, and Rippling. We’ve raised $70M+ from top VCs like Kleiner Perkins, which made its first sales-tech investment in over a decade with us. Since then, we’ve tripled ARR each year for 3 years running and grown a high-caliber team turning the art of sales into a scalable science.\nAbout the Role\nMost sales calls don't connect. The ones that do go through a maze: voicemails, phone trees, virtual assistants. Voice AI is the bet that an agent can navigate that maze, guide reps in real time, and turn the resulting transcripts into coaching insights that make whole teams convert better. We run roughly 100 million calls a week today - hyperscaler volume for real-time voice. We're hiring senior engineers to push both sides forward.\nWhat you'll do\nBuild real-time, low-latency Voice AI. Voicemail detection, IVR and virtual assistant navigation, in-call guidance for reps.\n\nBuild the call intelligence on top. Transcript analysis, conversation funnels, Markov models of the calls that convert vs. don't, the manager-side product where coaches find patterns across whole teams.\n\nWork directly with customers. Our biggest accounts have shared Slack channels with our engineers; you'll be on calls with users one day and shipping fixes back to them the next.\n\nMake foundational technical decisions. How low can latency go for a voice agent that's still useful? Given the first half of a call, what should the system recommend to maximize the chance the rep books a demo?\n\nMentor others on the team. Run code and design reviews, and pair on the hardest problems.\n\nYou might be a strong fit if:\n5+ years of engineering experience, with depth in something close to our stack (React, TypeScript, Node.js, Python). Bonus for experience operating real-time or low-latency systems at scale.\n\nProduction experience with AI features. For example, you've shipped a model under a strict latency budget and have opinions about evals.\n\nStrong opinions, held loosely, about what it takes to run real-time voice at hyperscaler volume - capacity, QoS, observability, the things that break first when you 10x traffic.\n\nNot afraid to listen to a few hundred calls to figure out what's actually broken.\n\nYou make the rest of the team faster.\n\nBased in San Francisco, excited to be in-office 3+ days per week.\n\nAt Nooks You'll Enjoy\nA world-class team. Around 40 engineers, mostly former founders or founding engineers and veteran builders from places like Applied Intuition, Scale, Airtable, Citadel, and Jane Street. Thirteen Olympiad medals across the team.\n\nA product that drives most of the company's revenue. Teams trial the dialer first and see 5-10x productivity gains within their first two weeks.\n\nTop-of-market compensation.\n\nEqual Employment Opportunity Statement\nNooks is an equal opportunity employer committed to fostering a diverse and inclusive workforce. We believe in providing equal employment opportunities to all individuals regardless of race, color, religion, gender, gender identity, sexual orientation, national origin, age, disability, veteran status, or any other characteristic protected by law.\nNooks does not discriminate in hiring, promotion, compensation, or any other employment practices, and we are committed to ensuring a workplace that is free from discrimination, harassment, and retaliation. We encourage individuals from all backgrounds to apply and join our team.","description_format":"text","description_chars":3888,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales Enablement","Conversational AI","Marketing & Sales AI"],"lifecycle":[{"event":"open","at":"2026-05-15T20:33:04Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.616,"p_room":0.28,"age_days":154,"expected_fill_days":65,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/nooks-senior-software-engineer-voice-ai","json_url":"https://alion.io/job/nooks-senior-software-engineer-voice-ai.json","meta":{"generated_at":"2026-10-17T20:20:48Z","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":4109,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":5957},"rest":"https://alion.io/mcp/rest/get_company?id=5957"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnooks-senior-software-engineer-voice-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%2Fnooks-senior-software-engineer-voice-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%2Fnooks-senior-software-engineer-voice-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/nooks-senior-software-engineer-voice-ai\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnooks-senior-software-engineer-voice-ai"}]}
