Proxify is Europe's largest network of vetted software developers. Companies come to us when they need an engineer who can contribute from week one. We find that person, vet them thoroughly, and match them. 20,000 applicants apply each month, and we need to pick the best 200 out of them.\nOur vetting isn't a step in the process. It is the product.\n\nThe problemSometimes we pick the wrong developer. It doesn't happen often, but when it does, a client's roadmap slips and a good engineer ends up somewhere they shouldn't be. Sometimes, that costs us the client for good.\nIt's also getting harder to tell the difference. Software Engineers build alongside AI agents all day now. An engineer who can't recall a sorting algorithm might be the best reviewer you've ever worked with. The one who aces the whiteboard might ship code they don't understand the impact of. The old signals are getting noisier, and nobody has agreed on the new ones.\nWhat we do have is one of the richest datasets anywhere on how software engineers perform: 20,000 applications a month, a network of 6,000, and engagement data on every one of them – who thrived on the job, who struggled, and why.\nNobody has worked out yet what that data actually predicts. Most people with strong opinions about technical hiring never get the chance to test them on a dataset like this.\nCan you help us pick the right 200 out of 20,000?\n\nBuild the new way of evaluating technical talentAs our Vetting Systems Architect, you'll own how Proxify identifies exceptional engineers in this new reality.\nYou will create better ways to understand how applicants think, build, review, debug, and make decisions. This may include technical interviews, tests, realistic work simulations, AI-enabled methods, and new formats that do not exist yet.\nThis is a senior individual-contributor role. You will own the direction end-to-end: what we evaluate, how we evaluate it, and how we scale it. Nobody is handing you a spec. You will report to the VP of Assessment and work closely with different teams influencing our technical evaluations today.\nYour work will shape the experience of thousands of applicants every month.\n\nWhat you’ll doOwn technical vetting across our engineering roles and seniority levels, turning strong on-the-job performance into clear, measurable signals.\n\nDesign evaluations. Build interviews, tests, work simulations, and scoring guides, including formats that do not exist yet.\n\nRethink evaluations for the AI era. Decide what matters when software engineers work with AI agents daily: directing and reviewing an agent, catching wrong output, debugging code they didn't write.\n\nUse AI in the work itself. Build and maintain technical content, improve consistency between interviewers, and support better decisions at volume.\n\nProve what works. Connect evaluation results with real engagement performance, filter signal from noise, A/B test, and scale what works.\n\nMake it hold at scale. Set the standards and quality controls for fair evaluations across thousands of applicants a month.\n\nWhat we’re looking forA strong hands-on software development background and deep expertise in at least one technical area.\n\nStrong analytical skills. You’re data-driven and understand reliability, consistency, bias, and predictive value.\n\nHands-on use of AI-assisted development tools, and a clear view of how they are reshaping software development.\n\nA practical point of view on where technical evaluation should go, and how you’d test it.\n\nThe communication skills to set direction and influence people without formal authority.\n\nWhy join and why this role mattersGet this right, and the right engineer gets a career-defining opportunity, and clients get stronger teams. Get it wrong, and you already know what that costs.\nYou'll work at the intersection of software development, AI, data, and product. You will have the freedom to challenge old hiring habits, test better ideas, and build the system that decides how technical talent gets recognized.\n\nPractical detailsLocation: Remote in Europe, with visits to our HQ in Stockholm.\n\nLanguage: English, C1 level or higher.\n\nLevel: Lead. A direction-setting individual-contributor role.","description_format":"text","description_chars":4271,"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":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"region"},{"name":"France","iso":"FR","kind":"region"},{"name":"United Kingdom","iso":"GB","kind":"region"},{"name":"Austria","iso":"AT","kind":"region"},{"name":"Belgium","iso":"BE","kind":"region"},{"name":"Bulgaria","iso":"BG","kind":"region"},{"name":"Croatia","iso":"HR","kind":"region"},{"name":"Czech Republic","iso":"CZ","kind":"region"},{"name":"Denmark","iso":"DK","kind":"region"},{"name":"Finland","iso":"FI","kind":"region"},{"name":"Hungary","iso":"HU","kind":"region"},{"name":"Ireland","iso":"IE","kind":"region"},{"name":"Italy","iso":"IT","kind":"region"},{"name":"Netherlands","iso":"NL","kind":"region"},{"name":"Norway","iso":"NO","kind":"region"},{"name":"Poland","iso":"PL","kind":"region"},{"name":"Romania","iso":"RO","kind":"region"},{"name":"Spain","iso":"ES","kind":"region"},{"name":"Sweden","iso":"SE","kind":"region"},{"name":"Switzerland","iso":"CH","kind":"region"},{"name":"Estonia","iso":"EE","kind":"region"},{"name":"Greece","iso":"GR","kind":"region"},{"name":"Iceland","iso":"IS","kind":"region"},{"name":"Latvia","iso":"LV","kind":"region"},{"name":"Liechtenstein","iso":"LI","kind":"region"},{"name":"Lithuania","iso":"LT","kind":"region"},{"name":"Luxembourg","iso":"LU","kind":"region"},{"name":"Malta","iso":"MT","kind":"region"},{"name":"Portugal","iso":"PT","kind":"region"},{"name":"Slovakia","iso":"SK","kind":"region"},{"name":"Slovenia","iso":"SI","kind":"region"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Freelance & Talent Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-11T21:14:16Z"}],"visa":[],"liveness":{"score":84,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.838,"p_room":1,"age_days":11,"expected_fill_days":35,"reasons":["seen:11","win:early"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/proxify-principal-engineer-technical-assessment","json_url":"https://alion.io/job/proxify-principal-engineer-technical-assessment.json","meta":{"generated_at":"2026-10-12T11:59:17Z","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":18749,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":13937},"rest":"https://alion.io/mcp/rest/get_company?id=13937"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fproxify-principal-engineer-technical-assessment"},{"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%2Fproxify-principal-engineer-technical-assessment"},{"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%2Fproxify-principal-engineer-technical-assessment"},{"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/proxify-principal-engineer-technical-assessment\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fproxify-principal-engineer-technical-assessment"}]}
