We provide personalized journeys for borrowers and lenders. Oper's technology streamlines the mortgage application process, eliminates paperwork, and increases transparency.\nThe fastest growing part of our business is Herman, our AI agent for mortgage origination. Herman reads documents, checks them, and works a credit file the way an analyst would, inside the regulated workflow of a real bank. It runs on sovereign EU infrastructure, because our clients cannot send mortgage data anywhere else. Phase by phase, it automates more of the origination process: first employed borrowers, then the self-employed, and onward. This is not a chatbot bolted onto old software. It is agentic software doing real work in a regulated environment.\nA passionate and engaging team of around 30 stellar Fintech operators works vigorously to transform European mortgages by enhancing efficiency and alleviating borrower anxiety. Backed by Bessemer Venture Partners and Motive Ventures, we have raised EUR 14 million, placing Oper at the forefront of revolutionizing mortgages in Europe. Oper currently has offices in Zürich, Switzerland, and Antwerp, Belgium.\nNow, we're looking for an AI Solutions Engineer to join our AI Squad and help shape the future of automated mortgages in Europe and beyond.\nYour Mission\nYou'll join the AI Squad, the team building Herman. This is a hands-on, hybrid role spanning AI engineering, product management, and solutions architecture. You'll scope and build working AI prototypes, take them in front of real banks to pressure-test against live mortgage workflows, and work alongside the team to turn these into working Herman features. You own delivery end-to-end: from a rough use case to a shipped capability, communicating progress clearly the whole way. This is an applied role, not a research one. We want a builder who can both code and collaborate, who is comfortable in front of a client in the morning and deep in a codebase in the afternoon.\nTasks\nWhat you'll do\nScope and build working AI prototypes - LLMs, RAG, agentic automation, and integrations - that solve concrete origination problems.\nEngage directly with clients: run workshops, gather requirements, demo, and iteratively refine solutions against the real workflows of regulated banks.\nDefine and manage AI use cases, structuring them functionally so they can scale beyond a single client.\nWork closely within your team to turn validated prototypes into production features.\nOwn delivery timelines and communicate progress clearly to both clients and internal stakeholders.\nWork AI-native\nBuilding agentic software is the job, and we expect you to build the way you ship: AI-first.\nWrite code AI-first: agents produce the bulk of your code under your direction, while you own the architecture, integrations, review, and quality. We measure your output in shipped value, not hand-typed lines.\nBuild agentic workflows that do real work: scaffolding prototypes and integrations from a spec, generating and running tests, drafting evaluation harnesses, and reviewing diffs.\nUse modern AI tooling as the default way you build, configure, and debug, not as an occasional helper.\nAim for a delivery cadence a non-AI-native engineer simply cannot match, and help us raise the bar on what an AI-native delivery function looks like at Oper.\nRequirements\nWhat you'll bring\n4 to 6 years of experience in software development, with hands-on AI/LLM work.\nStrong with Python and modern AI tooling: LLMs, RAG, agent frameworks, orchestration, and evaluation.\nAble to structure projects functionally and own delivery end-to-end, from scoping to shipped feature.\nComfortable being client-facing: running workshops, gathering requirements, and translating ambiguity into working software.\nComfortable working with flexible and loosely defined requirements, bringing your own structure where needed.\n Genuinely AI-native: agents already write most of your code and you build agentic workflows to multiply your output. You can name the tools, the workflows, and the concrete recent projects where AI gave you real leverage.\nExcellent communication skills.\nCreative and analytical mindset.\nAmbition to learn, experiment, and grow while staying humble and open-minded.\nFluency in English; additional languages (e.g. Dutch, German) are a plus.\nExperience in a relevant industry (financial services) and thriving in a scale-up environment are a plus.\nThis is an applied, client-facing, cross-functional role. We are not looking for researchers, \"idea people,\" or internal-only engineers.\nLocation & Setup\nBelgium-based candidates: hybrid setup with 2 to 3 days per week in our Antwerp office\nWorking in CET hours\nReporting to the CTO\nClose collaboration with the AI Squad, Product, and client-facing teams\nBenefits\nAs a fast-growing fintech, we're building a team where you can truly make an impact.\nWe offer:\nCompetitive annual salary, depending on experience\nEmployee stock options\n25 vacation days per year + 1 paid mental health day\nDynamic international team with 12 nationalities\nSupportive, inclusive, and collaborative culture\nLearning & Development budget with dedicated time for growth\nStructured onboarding with a dedicated mentor\nTravel budget to collaborate with teams in Antwerp\nAnnual company-wide Team G2G in an inspiring location\nExtra-legal benefits depending on your location\nFull support with local administration\nHealth insurance and pension scheme\nFlexible working hours\nAll equipment needed to do your best work\nThe position is also open for freelancers.\nInclusive at Our Core\nOper is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees and contractors. All applications are considered without regard to race, religion, gender, gender identity, sexual orientation, disability, age, or any other protected status.","description_format":"text","description_chars":5976,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Flexible schedule","Health insurance","Stock options"],"hiring_locations":[{"name":"Belgium","iso":"BE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Software & Embedded Finance","Mortgage Lending & Brokers"],"lifecycle":[{"event":"open","at":"2026-10-14T21:16:23Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.384,"p_room":0.28,"age_days":111,"expected_fill_days":33,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-15T05:35:04Z"},"pay":null,"html_url":"https://alion.io/job/oper-credits-ai-solutions-engineer","json_url":"https://alion.io/job/oper-credits-ai-solutions-engineer.json","meta":{"generated_at":"2026-10-15T05:35:04Z","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":8211,"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":450226},"rest":"https://alion.io/mcp/rest/get_company?id=450226"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Foper-credits-ai-solutions-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%2Foper-credits-ai-solutions-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%2Foper-credits-ai-solutions-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/oper-credits-ai-solutions-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Foper-credits-ai-solutions-engineer"}]}
