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 looking for a Head of Engineering to own technology across Labhouse. This is a hands-on, full-stack engineer with a leadership mindset who can take any technical challenge in the company, whether it lives inside one of our apps or cuts across the whole business, and solve it with full ownership.\nYou’ll work directly with the CTO and the founders. One week you might be redesigning a core backend service, the next you might be hardening our security, rethinking how we handle user data, or shipping an AI feature into a new app. Your scope includes:\nApps: new product launches, performance, and reliability at scale.\n\nBackend & Infrastructure: core services, cloud architecture, scalability, and cost efficiency.\n\nSecurity & Data Privacy: protecting our users and the company by design.\n\nData: pipelines and the acquisition and performance data that drive our decisions.\n\nAI & Automation: integrating AI models into our products and automating how we work.\n\nNo two challenges look the same here. If you thrive when the problem is new and nobody has the answer yet, you’ll likely enjoy this role.\nAbout You\nAcademic background:\nDegree in Computer Science, Telecommunications Engineering, or a related technical field.\n\nTechnical expertise:\nStrong full-stack profile with real hands-on depth across frontend, backend, and infrastructure.\n\nProven track record of owning technical projects end to end across very different domains: product, infrastructure, security, data, AI.\n\nExperience building and launching new products (0→1) and scaling them (1→100).\n\nHands-on experience designing cloud infrastructure and improving performance and reliability for systems used by large user bases.\n\nSolid understanding of security, data privacy, and data infrastructure.\n\nExperience integrating AI models and building automations that save real time.\n\nExceptional learning speed: you’ve repeatedly taken on unfamiliar technologies or domains and delivered results fast.\n\nToday our stack includes Flutter, Dart, TypeScript, GCP, and SQL, but we don’t hire based on specific frameworks. We hire people who can learn quickly and figure things out.\n\nOwnership and team building:\nYou solve problems yourself first. You’re comfortable owning a challenge alone from diagnosis to delivery, and you bring in whatever resources it needs, whether that’s AI tools, external partners, or other teams.\n\nExperience hiring engineers and building teams from scratch. You know what great looks like and can attract and assess it when a challenge needs dedicated people.\n\nAbility to set the technical bar: architecture, standards, and practices that let us move faster without adding complexity.\n\nYou own outcomes, not tasks. When something breaks or a new challenge appears, you take it and solve it.\n\nComfortable operating in ambiguity, prioritising by impact, and making decisions with incomplete information.\n\nProduct-first mindset with an eye for detail and a passion for great user experiences.\n\nCommunication:\nGood level of spoken and written English, Spanish is a Plus\n\nAbility to collaborate effectively with cross-functional teams, including design, product, and marketing.\n\nAbility to explain complex technical decisions clearly to non-technical stakeholders.\n\nNice to have:\nExperience as an early engineer or tech lead in a startup that scaled fast.\n\nBackground in subscription-based mobile apps or consumer products.\n\nHands-on mobile development experience (Flutter is a plus).\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\nPermanent contract with a competitive compensation package.\n\nHigh-end equipment for your development.\n\nA young and top entrepreneurial team in a dynamic startup environment.\n\nOpportunity to lead, grow, and take on big challenges.\n\nWork with cutting-edge technologies, including the chance to integrate AI models into new 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":5015,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Flexible schedule"],"hiring_locations":[{"name":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-09-11T04:44:23Z"},{"event":"close","at":"2026-09-22T09:31:55Z"},{"event":"reopen","at":"2026-10-29T10:26:49Z"}],"visa":[],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.717,"p_room":0.36,"age_days":110,"expected_fill_days":70,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/labhouse-staff-software-engineer","json_url":"https://alion.io/job/labhouse-staff-software-engineer.json","meta":{"generated_at":"2026-11-01T20:55:45Z","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":31947,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":678665},"rest":"https://alion.io/mcp/rest/get_company?id=678665"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flabhouse-staff-software-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%2Flabhouse-staff-software-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%2Flabhouse-staff-software-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/labhouse-staff-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flabhouse-staff-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":711067}},{"tool":"search_jobs","arguments":{"company":"labhouse.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":711067},"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.
