AI agents that handle millions of live interactions every day for Fortune 500 banks and insurers, end-to-end. Interactions are 3x-ing monthly. We're hitting problems most startups never encounter: real-time voice AI at scale, legacy banking infrastructure, enterprise telephony, and building regulatory frameworks in the US.\nThe role\nAs the Senior Software Engineer you'll.....\nBuild and own core product features: Backend systems, APIs, voice infrastructure, wherever the product needs you. Code ships daily and goes live for Fortune 500 clients.\nWork on things most engineers never touch: telephony systems, real-time voice processing, and integrations with legacy financial infrastructure. The problems are hard. That's the point.\n95%+ of your time will be coding and building.\nWe're looking for engineers who can own one of these areas: the orchestration layer that coordinates our voice AI systems, infrastructure scaling and low-level performance, security as a generalist building for Fortune 500 financial institutions, or product engineering close to users finding high-leverage wins.\nKnow what it feels like when things are working: real customers, real revenue, a product people actually need. You also know the chaos, the pace, the things that break at the worst possible time. You've seen both sides and you want to do it again with a team that's already found traction.\nWhy Domu\nReal traction. Post $XXM in revenue, Fortune 500 customers, 12x YoY growth. This isn't a bet on an idea. The product works and customers are paying for it.\nYou'll learn how enterprise deals work from an engineering seat. You'll see the direct line between your code and revenue.\nAI First company with $1M+ revenue per employee.\nEarly enough to shape the product, the team, and the culture.\nHow we work\nWe do dailies. We groom tickets. But we keep process light and in service of the work, not the other way around. We'd rather spend time building than talking about building.\nWe care about doing great work. Not just shipping, but shipping something you're proud of.\nOwnership here is real. You won't be handed tasks from a backlog. You'll see what needs to happen and do it. That's how a small team ships to Fortune 500 customers.\nWe hire people whose judgment we trust, then get out of their way. No passengers.\nWhat you bring\n3+ years of experience as a software engineer\nPreviously worked at a Series A (or similar stage) startup and went through the same hypergrowth challenges Domu is facing\nExperience dealing with legacy systems and refactoring them into sustainable, scalable architectures\nStrong backend fundamentals - can own features end-to-end from design to production\nProficiency in TypeScript and/or Python\nExtras we'd be excited about\nTelephony/Voice infrastructure - SIP, SRTP, WebRTC, or platforms like Telnyx, Twilio, LiveKit\nHigh-throughput distributed systems - queue workers, event-driven architectures, handling 1M+ daily transactions\nPostgreSQL at scale - query optimization, replication, connection pooling\nKubernetes - production deployments, scaling stateful services\nReal-time data pipelines - ClickHouse, Kafka, or similar OLAP/streaming solutions\nAWS infrastructure - SQS, containerized deployments\nCompliance-conscious environments - SOC 2, ISO 27001, or fintech/enterprise security requirements\nExperience with AI/ML integrations in production (LLMs, voice AI)\nFamiliarity with contact center / dialer systems\nYou've been through the early stages of a startup before.\nYou care about the craft. You want to build something good, not just something that works.\nIdeal archetypes:\nHead of Eng / Tech Lead at a Series A/B startup (5-20 engineers), built and scaled core infra from scratch\nSenior Engineer who was one of the first 10 hires and is ready for that feeling again\nFounding Engineer through Series B/C, owns systems end-to-end, wants a new zero-to-one challenge\nStaff Engineer at a Series C/D slowed by process, wants to move fast again\nRepeat startup engineer, 2-3 stints, specifically seeks small teams with hard problems\nWhat we offer\nHealthcare\nweekly stipend for food and transportation\ngym membership\nequipment budget (strict rules on noisy mechanical keyboards)\nwhatever tools you need\nInterview with Head of Engineering (Kai)\nTechnical screening\nTechnical take-home challenge\n1 hour interview with another 2 engineers\nPaid trial","description_format":"text","description_chars":4483,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Gym membership"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Call Center Services"],"lifecycle":[{"event":"open","at":"2026-08-27T22:46:07Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.597,"p_room":0.55,"age_days":50,"expected_fill_days":37,"reasons":["conf:3","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":210000,"is_top_pay":true},"html_url":"https://alion.io/job/domu-technology-inc-senior-software-engineer","json_url":"https://alion.io/job/domu-technology-inc-senior-software-engineer.json","meta":{"generated_at":"2026-10-18T04:40:34Z","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":6983,"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":2071},"rest":"https://alion.io/mcp/rest/get_company?id=2071"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdomu-technology-inc-senior-software-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%2Fdomu-technology-inc-senior-software-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%2Fdomu-technology-inc-senior-software-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/domu-technology-inc-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdomu-technology-inc-senior-software-engineer"}]}
