We deploy purpose-built agents that resolve real workflows end-to-end, compliantly and at scale across insurance and financial services.\nWe’re a fast-growing startup at the forefront of the AI revolution, helping companies scale smarter and cut costs. Our platform connects customer and employee interactions with back-office systems to automate complex workflows end-to-end - all delivered with the highest standards for auditability, explainability, and governance.\nBacked by top-tier VCs, Notch has raised $45 million to date, including a $30 million Series A in March 2026 led by Headline, with participation from Lightspeed, Jibe Ventures, Illuminate Financial, Munich RE, and Phoenix.\nAbout the Role:\nWe're looking for really good engineers who want to build great software.\nOur platform runs hundreds of thousands of AI-driven conversations and workflows for enterprise customers who can't tolerate a wrong answer. The hard problems here don't sit in one layer - they sit in how the layers fit together: an LLM pipeline that has to be deterministic exactly where it matters, a data model where a leak between customers is a severity-1, long-running workflows that have to survive restarts and retries, and one product that has to ship into a shared cloud, a dedicated single-tenant environment, and a customer's own data center without becoming three different products.\nYou'll own problems all the way through from the product decision, through the data model and the backend, to what the user actually sees. Small team, real ownership, decisions that stick.\nWhat You'll Do:\nOwn features end to end: product conversation → schema → API → UI → how it behaves in production.\nDesign the systems behind our AI agents - pipelines, orchestration, retries, guardrails, evaluation - so behavior is predictable and explainable.\nBuild backend services and data models that stay correct and stay fast as volume grows - across shared, single-tenant, and on-prem deployments.\nBuild the product surfaces our customers and our delivery teams use to configure, monitor, and audit agents.\nOwn your code in production: CI, deploys, observability, alerting, and the debugging that follows.\nWork on how we ship, build and release pipelines, environments, and the infrastructure that lets one codebase deploy into very different customer environments.\nMake the call on where complexity is worth it and where things should stay boring.\nRaise the bar around you: code review, design review, mentoring, and the standards that keep a codebase alive two years from now.\nRequirements\nYou're a Good Fit If:\nYou have 5+ years of engineering experience, 3+ of them building real products across both frontend and backend.\nYou're strong in at least one modern typed language and ecosystem: TypeScript, Python, Go, Java, C#. We write TypeScript, and we expect you to be productive in it fast, but we hire for how you think, not for which language you last used.\nYou're genuinely full-stack - you can debug a React render, a slow query, and a stuck queue in the same day.\nYou know relational databases properly: schema design, indexes, transactions, and what happens under concurrency.\nYou've worked with distributed systems and know where the race conditions hide.\nYou're product- and solution-oriented - you ask what the customer is trying to do before you ask what to build.\nYou can take a vague, complex problem and turn it into an architecture that Just Works.\nYou care about your teammates, and you're looking to both learn and teach.\nYou work AI-natively. You use coding agents seriously, and you build the things that make them useful - skills, agents, evals, internal tooling, context that makes the whole team faster. This is how we work, not a side project.\nYou believe a small, dedicated team beats a big one.\nYou've built LLMs in production - not a demo, but something with evals, guardrails, and regression testing behind it.\nYou've worked in a regulated or high-stakes environment where auditability wasn't optional.\nYou take pride in frontend architecture - accessible, responsive, fast components.\nAn early-stage startup is what you're actively looking for: hard work, processes that aren't fully defined, and a lot of freedom.\nOur Stack\nWe treat the stack as a set of tools, not as the solution - the specifics change, the thinking doesn't. The essentials:\nTypeScript everywhere, strict, across a single monorepo.\nBackend: Node.js, PostgreSQL, Redis, and a workflow-orchestration layer for everything long-running.\nAI: the major model providers behind our own agent, retrieval, and evaluation layer.\nFrontend: React, in real-time product surfaces our customers and delivery teams work in daily.\nInfrastructure: multi-cloud, and deployed inside the customer's own environment where regulation requires it - so portability and data residency are design constraints, not afterthoughts.\nOur Culture\nExtreme ownership and accountability\nHigh standards, fast pace, and lots of freedom\nMinimal bureaucracy, evolving processes\nPeople who want to grow beyond a narrow role definition\nA small, commando-like team where your impact is immediate and visible\nwork from our office in the Bursa, Ramat Gan","description_format":"text","description_chars":5289,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Financial Services","AI Agents"],"lifecycle":[{"event":"open","at":"2026-10-14T05:27:08Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":31,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/notch-senior-full-stack-engineer","json_url":"https://alion.io/job/notch-senior-full-stack-engineer.json","meta":{"generated_at":"2026-10-15T13:27:28Z","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":20735,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":2108498},"rest":"https://alion.io/mcp/rest/get_company?id=2108498"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnotch-senior-full-stack-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%2Fnotch-senior-full-stack-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%2Fnotch-senior-full-stack-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/notch-senior-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnotch-senior-full-stack-engineer"}]}
