Manual, document-heavy audits waste expert time while demand keeps rising. Our AI-powered software and specialized AI agents remove the repetitive work so auditors can focus on judgment.\nBacked by top-tier VCs with >15m funding, with a working product and paying customers, we’re rapidly scaling.\nWe value first-principles thinking, speed, trust, and kindness. We build side by side in our Berlin office.\nYour Role\nWe're looking for an experienced engineer who's happy anywhere in the stack and turns complex audit workflows into product auditors rely on every day. You pick up whatever a problem needs, from the data model to the interface to the agents behind it.\nA lot of what we build has no reference implementation. You're comfortable wading into something nobody has solved yet and shipping a first version that actually works.\nOur engineering team is a small, flat group of builders: strong ICs who open a laptop when they see a problem instead of scheduling a meeting. Everyone owns real product and architecture decisions, and that's exactly what we want more of.\nWhat you'll do\nBuild the interfaces auditors work in, partnering with design to turn complex flows into something that feels effortless\n\nBuild and improve the agents at the core of the product, plus the harnesses and eval pipelines around them\n\nMake the long-running workflows behind the product reliable and debuggable, so failures surface fast instead of silently\n\nUse AI heavily in your own workflow to move faster, without ever shipping output you can't stand behind\n\nDrive the how in RFCs and technical discussions with other engineers, and partner with product on the what\n\nQualifications\nYou'll fit here if you:\nHave 5+ years shipping production web applications across the stack\n\nWrite production APIs and model the data behind them so it holds up under multi-tenancy and load\n\nAre strong on the frontend and can build genuinely complex UI\n\nGet how LLM agents actually work: agents, harnesses, tool use, and measuring quality with evals\n\nKeep up with where AI is moving and bring the latest tools into how you work to make yourself faster\n\nBring a strong product mindset and real ownership of outcomes\n\nMake architectural decisions, weigh trade-offs, and build things other engineers can extend\n\nAre comfortable with ambiguity and work things out from fundamentals when there's no established answer\n\nNice-to-haves that are a plus:\nHands-on experience building agents, harnesses, or eval pipelines\n\nData-dense or workflow-heavy B2B products\n\nScaling multi-tenant systems as data and traffic grow\n\nAudit, finance, compliance, or another domain where being wrong is expensive\n\nEarly-stage startup or fast-moving engineering environment\n\nNo one checks every box. If you ship across frontend, backend, and data and own what you build, let's talk.\nOur tech\nReact, TS, Tailwind, TanStack\n\nPython, Postgres, Temporal, Kafka, Redis\n\nGCP, Azure, k8s\n\nGitHub, Linear, Slack, Notion\n\nWhat We Offer\nHigh impact & growth: Front-row seat to scaling an AI startup with real ownership from day one\n\nMission-driven culture: First-principles thinking, bold ideas, and a supportive team\n\nAttractive compensation: competitive salary + meaningful equity\n\nPersonal development: Learning budget for courses and conferences\n\nTrue Berlin startup environment: Central Berlin office, team lunches, retreats, flexible vacation\n\nInterview process\nFirst Call - Intro to Cortea with our Founders Associate Liza\n\nSecond Call - Technical interview with our Member of Technical Staff Jendrik\n\nThird Call - Deep dive into our culture with our Co-Founder Philipp\n\nOn-site Half-Day (Berlin) - Meet the team and work on a real problem together","description_format":"text","description_chars":3756,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial AI","Accounting & Tax Software"],"lifecycle":[{"event":"open","at":"2026-09-11T08:27:04Z"}],"visa":[],"liveness":{"score":39,"band":"fade","label":"Fading","p_open":1,"p_active":0.713,"p_room":0.55,"age_days":45,"expected_fill_days":36,"reasons":["conf:3","win:tail"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/cortea-seniorstaff-product-engineer-mfx","json_url":"https://alion.io/job/cortea-seniorstaff-product-engineer-mfx.json","meta":{"generated_at":"2026-10-25T12:24:43Z","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":17900,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":673528},"rest":"https://alion.io/mcp/rest/get_company?id=673528"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcortea-seniorstaff-product-engineer-mfx"},{"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%2Fcortea-seniorstaff-product-engineer-mfx"},{"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%2Fcortea-seniorstaff-product-engineer-mfx"},{"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/cortea-seniorstaff-product-engineer-mfx\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcortea-seniorstaff-product-engineer-mfx"}]}
