They move fast. And they're looking for someone who thrives in that environment, not despite it.\nYour mission\nYour job isn't just to write code, it's to solve problems. That means asking the hard questions before touching a keyboard, understanding the why behind every request, cutting scope ruthlessly when needed, and shipping things that actually move the needle.\nYou'll work across the full stack, back-end services, front-end dashboards, automations, AI pipelines; and you'll own features end-to-end (from understanding the problem, to scoping the solution, to deploying and iterating).\nThey want someone who questions before building, and knows when the best solution is a simpler one.\nWhat you’ll do\nOwn problems, not just tickets: you'll push back when something isn't worth building, and move fast when it is.\nBuild and maintain back-end services in Python (FastAPI, Pydantic), with a strong focus on reliability and maintainability.\nDesign and automate complex workflows: document processing, email handling, third-party API integrations and OCR (using tools like n8n, LangChain, MCP, and similar).\nBuild front-end interfaces: dashboards, internal tools, chat experiences that are fast, clear, and genuinely useful (React).\nOwn deployment and monitoring end-to-end.\nWhat they’re looking for\nSolid production experience with Python (FastAPI, Pydantic, Pandas) or Node.Js and JavaScript/TypeScript (React and Next), you've shipped real things that real people use.\nComfortable owning both front-end and back-end without needing to split the work.\nExperience with deployment, infrastructure, and monitoring, you don't throw things over the wall.\nStrong product instinct: you think about users and outcomes, not just systems and tasks.\nIntellectual honesty: you push back on bad ideas (including your own), and you'd rather solve the right problem simply than the wrong one perfectly.\nAt ease with ambiguity: you can go from a vague problem to a shipped solution without someone holding your hand every step of the way.\nHow they work\nReal problem, real users: You won't be building in a vacuum. You'll work closely with the accountants, advisors, and small business owners who use what you ship - understanding their pain firsthand, and turning it into solutions that actually work for them. These are people running real businesses, and getting it right matters.\nFlexibility & hybrid work: They believe in ownership and responsibility over schedules. They trust people to manage their time and deliver results. They also value working side by side: they enjoy being together in the office to collaborate, think, and build as a team.\nTools & setup: AI-first tools and workflows, latest-generation hardware, and everything you need to work faster and better. If a tool helps you move quicker or think clearer, they want you to have it.\nGrowth & development: You’ll have a dedicated training budget to invest in whatever helps you grow. They’re clear about where they are and where they’re going as a company, and you’ll have periodic performance reviews to support your development and career progression.\nCompensation: They believe in a meritocratic culture: your impact and results directly shape your growth and progression. They also offer flexible compensation (transport, restaurants, and other benefits) to make your day-to-day easier.","description_format":"text","description_chars":3594,"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":["Hybrid work"],"hiring_locations":[{"name":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Recruiting & Staffing"],"lifecycle":[{"event":"open","at":"2026-09-11T09:11:30Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.124,"p_room":0.28,"age_days":175,"expected_fill_days":23,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/resilientco-full-stack-engineer","json_url":"https://alion.io/job/resilientco-full-stack-engineer.json","meta":{"generated_at":"2026-10-22T15:48:18Z","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":15710,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":686196},"rest":"https://alion.io/mcp/rest/get_company?id=686196"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fresilientco-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%2Fresilientco-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%2Fresilientco-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/resilientco-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fresilientco-full-stack-engineer"}]}
