Kalepa is building AI that can perform that work.\nWe create professional-grade AI systems for insurers: software that can read, reason, decide, and act inside real workflows and operate over long-time horizons. Kalepa begins by augmenting professionals with the tools to succeed at their jobs. That earns us the right to learn from real decisions, capture decision traces, and automate what can be automated successfully over time.\nOur products are already in production with leading insurers, driving measurable outcomes and expanding across functions. The opportunity is far broader than any single workflow: to build the AI operating system for decision-making across insurance. For people who want to work on AI that matters, in a sector where correctness, trust, and real-world impact count, Kalepa is just getting started.\nKalepa is backed by leading investors such as IA Ventures and Inspired Capital, and our team brings experience from Facebook, Palantir, Google, Amazon, McKinsey, Mastercard, and Uber.\nOur Values (This is important):\nMany organizations have a dusty list of corporate values that no one ever follows. Kalepa is not one of those companies. Our values are designed to unlock the potential of our employees. \nSuccess at Kalepa is bred from five core principles:\nHustle and Determination - We hire people who take full ownership of their craft and relentlessly pursue excellence with speed and determination. We choose the hard problems and do not give up. This is the foundation of how we work and how we win.\nDeliver Customer Impact - We're obsessed with customer impact. Every feature, every line of code, every decision is measured against one question: does this help insurers make better decisions? If it doesn't drive speed, accuracy, or profitability for our customers, we don't build it.\nMeritocracy - We're building something exceptional, and that requires exceptional people and ideas. We have a high bar but we reward excellence with rapid growth. If you're the best at what you do, you'll thrive here.\nTransparency - We value honest, transparent communication over politics. We challenge ideas, not people. We say what needs to be said, even when it's hard. This is how we solve problems fast and find the truth.\n Experiment Relentlessly - Many of the problems we face have never been solved before. We tackle them by testing quickly, measuring rigorously, and iterating until we find the path forward. Speed of learning is our advantage.\nIn addition to our NY office, we have remote employees speaking 10+ languages across the globe. But we invest in bringing our people together both for regional meetups and global offsites (2021 - Playa Del Carmen | 2022 - Rome | 2023 - Buenos Aires | 2024 - Lisbon | 2025 - Cartagena).\nKalepa’s culture isn’t for everyone, and that’s ok. But for the people who are a fit, they can’t imagine working elsewhere. \nAbout the role:\nSalary range: $80k - $165k USD*\nWe are looking for smart engineers who love to code, seek challenging problems and appreciate recognition for excellent work. As part of the Core UX team, you will focus on refining existing product functionality to deliver an exceptional user experience. Your work will center on ensuring consistency across the product, maintaining a cohesive look and feel, and implementing performance improvements that directly impact end users. You’ll be paying close attention to the layout, interactions, responsiveness, and visual polish, that collectively give the product a premium, well-crafted feel. This role is ideal for someone who enjoys iterative improvement, cares deeply about quality, and wants to shape the everyday experience of our users.\nYou'll collaborate with a global team of full-stack, data, ML, and DevOps engineers to build scalable backend solutions as we continue to grow. We're a small team where individual contributions have an outsized impact on both our technology and our business.\nYou'll be right at home if you:\nHave 5+ years of software engineering experience, ideally with a track record of improving and polishing functionalities to bring premium user experience.\nEmbody hustle and grit, you're excellent at your craft and relentless in pursuing it.\nTake full ownership of your work and drive projects to completion with minimal oversight.\nCommunicate proactively, surfacing blockers, asking the right questions, keeping stakeholders in the loop.\nThrive on experimentation: you're comfortable testing ideas, measuring results, and iterating quickly on problems no one has solved before.\nHave strong fundamentals in system design, debugging, and problem-solving.\nYou have experience in a modern FE framework, preferably React.\nKnow Javascript, Typescript, or Python, though we're open to strong candidates from other OO backgrounds.\nHave experience with serverless technologies (Lambda, EC2), asynchronous workflows, and cloud environments.\nAre comfortable with relational databases, ideally PostgreSQL.\nBonus: experience with LLMs/generative AI, distributed systems.\nWhat you’ll get:\nCompetitive salary (based on experience level)*.\nSignificant equity options package.\nWork with an ambitious, smart, global, and fun team to transform a $1T global industry.\n20 days of PTO a year.\nGlobal team offsites.\nPhone reimbursement. Gym reimbursment.\nStudent stipend.\n*The salary range listed is an estimate and will vary based on a variety of factors. Final compensation will be determined during the offer stage based on relevant experience, performance during the interview process, and geographic location, and may therefore differ from the posted range.","description_format":"text","description_chars":5749,"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":[{"name":"United States","iso":"US","kind":"country"},{"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":["Financial AI","InsurTech"],"lifecycle":[{"event":"open","at":"2026-09-03T10:13:46Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.55,"p_room":0.28,"age_days":308,"expected_fill_days":147,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-20T05:45:00Z"},"pay":{"stated_usd_annual":165000,"is_top_pay":false},"html_url":"https://alion.io/job/kalepa-senior-full-stack-engineer-core-ux-europe","json_url":"https://alion.io/job/kalepa-senior-full-stack-engineer-core-ux-europe.json","meta":{"generated_at":"2026-10-21T05:02:51Z","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":7453,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":960},"rest":"https://alion.io/mcp/rest/get_company?id=960"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkalepa-senior-full-stack-engineer-core-ux-europe"},{"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%2Fkalepa-senior-full-stack-engineer-core-ux-europe"},{"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%2Fkalepa-senior-full-stack-engineer-core-ux-europe"},{"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/kalepa-senior-full-stack-engineer-core-ux-europe\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkalepa-senior-full-stack-engineer-core-ux-europe"}]}
