Our products, including Invoice Fly and Summary AI, are designed to make everyday tasks faster, smarter, and simpler through a subscription model that puts the user first.\nWe were founded by Andrés Bou and Horacio Martos, the duo behind SocialPoint (acquired by Take-Two Interactive), and we operate with the mindset of a product company: small teams, high ownership, and a relentless focus on building things that matter.\nWould you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below.\nAbout the Role:\nWe’re bringing AI Agents into Summary AI and Invoice Fly, and you’ll be the one building them from scratch. This isn’t a role where you join an existing system and pick up tickets. You’ll own the whole cycle: decide what to build, design the architecture, implement it, measure how it performs with real users, and keep iterating until it works.\nThese won’t be thin wrappers around an LLM. You will build multi-agent systems that do real work for millions of users, and you’ll build the foundation underneath them: orchestration, tool use, context management, evaluation, and human-in-the-loop controls.\nWhat You’ll Do\nDesign and build our agent architecture from the ground up.\n\nShip agentic features into Summary AI and Invoice Fly.\n\nSet up evaluations to measure quality, catch failures, and guide improvements.\n\nIterate quickly based on real usage and data.\n\nTrack the latest models, tools, and techniques, and bring the best ones into our products.\n\nAbout You:\nYou have 5+ years of experience building production systems.\n\nYou’ve built agents that real people use, and you know what it takes to make them reliable.\n\nYou take full ownership, from a blank page to production and beyond. You make the architecture decisions yourself and see them through.\n\nYou know how to evaluate AI systems, not just build them, and you use data to decide what to fix next.\n\nYou keep up with AI. You try new models and tools as they come out, and you know which ones are worth adopting.\n\nYou ship fast and iterate, without lowering the bar on quality.\n\nYou communicate clearly with everyone you work with. You explain technical tradeoffs clearly, listen to what each team needs, and keep everyone aligned.\n\nProblem-solving and product focus:\nExcellent problem-solving and analytical skills, with the ability to resolve complex technical challenges.\n\nEye for detail and a product-first mindset, with a passion for creating exceptional user experiences.\n\nSelf-driven, entrepreneurial attitude with the ability to work autonomously and take ownership of projects.\n\nExcellent communication skills.\n\nNice to Have:\nExperience with subscription apps or mobile products\n\nContributions to open-source AI tooling\n\nWhat we Offer:\nRemote work from anywhere in Spain. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week.\n\nFlexible working hours.\n\nHigh-end equipment for your development.\n\nPermanent contract with competitive compensation.\n\nA young and top entrepreneurial team in a dynamic startup environment.\n\nOpportunity to lead, grow, and take on big challenges.\n\nHiring Process\nInitial Interview: Meet with our Talent Acquisition Lead to discuss your background and fit for the role. We’ll also ask you to share your proudest projects.\n\nHiring Manager Interview: A deep dive into your experience.\n\nTechnical Assessment: Showcase your expertise through a practical task.\n\nFinal Interview: A conversation with our leadership team to align on vision and expectations.\n\nOffer: Join our team and lead the development of our future-shaping apps!\n\nYou should Know:\nLabhouse is proud to be an equal-opportunity employer. However you identify or whatever your journey to this point, we welcome all candidates to apply for the position that inspires them.\nCome join us and help us build a company that everyone is proud to be part of.","description_format":"text","description_chars":4110,"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":["Flexible schedule"],"hiring_locations":[{"name":"Spain","iso":"ES","kind":"country"},{"name":"Barcelona","iso":null,"kind":"city"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-11-11T20:30:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":104,"reasons":["conf:2","win:early"],"computed_at":"2026-11-11T22:43:18Z"},"pay":null,"html_url":"https://alion.io/job/lab-house-ai-engineer-agents","json_url":"https://alion.io/job/lab-house-ai-engineer-agents.json","meta":{"generated_at":"2026-11-11T22:43:18Z","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":45054,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":678665},"rest":"https://alion.io/mcp/rest/get_company?id=678665"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flab-house-ai-engineer-agents"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Flab-house-ai-engineer-agents"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Flab-house-ai-engineer-agents"},{"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/lab-house-ai-engineer-agents\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flab-house-ai-engineer-agents"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4092525}},{"tool":"search_jobs","arguments":{"company":"labhouse.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4092525},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
