The distribution system failed them: too slow, too opaque, too confusing.\nOver 90% of commercial insurance is still human-led. We're building the inverse: 90%+ AI-led, pushing toward the higher 90s. Not by patching legacy workflows-by building AI that makes humans more effective, improves the customer experience, and eliminates friction at every step.\nWe're adding ~1,000 customers per month. We've grown 100x since last year. We're looking to do even more this year-and that's why we're hiring.\nYou build the systems the rest of engineering depends on. When they compound, everyone gets faster.\nThe Thesis\nHarper runs 200+ services across Railway and AWS. We orchestrate N parallel agentic workloads. Our AI systems make thousands of decisions a day, and every decision needs to be traceable, evaluated, and cheaper to run tomorrow than it is today. The infrastructure underneath all of that is the difference between a company that scales and one that stalls.\nGreat platform engineering here isn't invisible-it's the reason product ships fast. When observability catches a silent failure before a customer does. When a pooling layer makes connection exhaustion a non-issue. When developer velocity doubles because someone built the tool nobody knew they needed. That leverage compounds across every other engineer on the team.\nThe Role\nYou're an infrastructure-focused engineer with depth across databases, AWS, networking, observability, SRE, CI/CD, and AI tooling. You build the systems and tooling the rest of engineering depends on-optimized for performance, reliability, and developer velocity.\nYou work directly with founders and alongside the product engineers who ship features on top of what you build. You see where things break at scale, design the fix, and ship it before it becomes a fire. When something goes wrong at 2 AM, you're the one who gets paged-and you'd rather build the system that prevents the page than accept it as inevitable.\nWe are hiring platform engineers across all levels, which we determine during the interview process.\nWhat You'll Do\nOwn core infrastructure - Databases, AWS services, networking, CI/CD; the systems every engineer depends on\n\nBuild for scale - Thousands of concurrent AI operations, sub-second response times, cost-effective under load\n\nDesign observability that works - System-level errors AND business-level silent-failure detection; we find out something is broken from an alert, not from a person hours later\n\nOrchestrate agentic workloads - N parallel agent instances doing non-deterministic work, running reliably and cost-effectively as N grows\n\nMultiply developer velocity - The tooling and abstractions that let product engineers ship in days instead of weeks\n\nOwn reliability end-to-end - SLOs, on-call, incident response, and the post-mortems that make it rarer next time\n\nBuild the eval infrastructure - Systems that measure whether AI outputs are getting better, not just running\n\nYou Might Be a Fit If...\nYou've owned production systems at scale-not contributed to, owned; you got paged when they broke\n\nYou write code with AI (Cursor, Claude Code) and know how to leverage it for infrastructure work\n\nYou have depth across at least two of: databases, cloud infrastructure (AWS), networking, observability, or CI/CD\n\nYou've designed systems that survive real load-retries, DLQs, back pressure, idempotency, the whole stack\n\nYou care about developer experience-the tools other engineers use are as much your product as the customer-facing ones\n\nYou'd rather build the system that prevents the fire than firefight forever\n\nRequirements\nSoftware engineering experience with a platform, infrastructure, or SRE focus (level determined during interviews)\n\nProficiency in Python, TypeScript, Go, or similar\n\nProduction experience with cloud infrastructure (AWS), databases (Postgres), and observability tooling\n\nTrack record of building systems and tooling that other engineers depend on\n\nBased in San Francisco or willing to relocate\n\nNice to Have\nExperience orchestrating AI/ML workloads at scale (agent frameworks, LLM inference infrastructure)\n\nVoice AI or real-time systems experience\n\nDeep AWS experience (ECS, Lambda, RDS, VPC design)\n\nPrior startup experience-especially at companies that scaled through hypergrowth\n\nCompensation & Logistics\nSalary: $140,000-$280,000 depending on experience + performance bonuses & equity\n\nLocation: San Francisco, in-office. Based in SF or willing to relocate.\n\nSchedule: Monday-Friday, very early morning start, in-office five days a week.\n\nBenefits: Uber commuter benefits; breakfast, lunch, and dinner provided; snacks, drinks, and coffee daily; free gym membership; health, dental, and vision insurance.\n\nThe Process\nTechnical screen - 60 min remote: project deep dive + system design\n\nSuper Day on-site - meet the team, sit in on the operation, do real work alongside us.\n\nTo Apply\nIf you want to build AI capabilities against business problems you discover yourself, ship code that runs a real business, and work with people who show up with the same intensity every day-send your resume and a link to something you've built that had measurable business impact.","description_format":"text","description_chars":5305,"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","Gym membership","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Manufacturing"],"lifecycle":[{"event":"open","at":"2026-07-24T00:02:56Z"}],"visa":[],"liveness":{"score":37,"band":"fade","label":"Fading","p_open":1,"p_active":0.62,"p_room":0.6,"age_days":85,"expected_fill_days":93,"reasons":["conf:3","win:late","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":280000,"is_top_pay":true},"html_url":"https://alion.io/job/harper-platform-engineer","json_url":"https://alion.io/job/harper-platform-engineer.json","meta":{"generated_at":"2026-10-17T18:46:10Z","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":1722,"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":5322},"rest":"https://alion.io/mcp/rest/get_company?id=5322"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fharper-platform-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%2Fharper-platform-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%2Fharper-platform-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/harper-platform-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharper-platform-engineer"}]}
