The Mobile-First Company\nMost tools for small businesses weren’t built for real operators.\nThey were built for employees in offices, not people running a business from their phone.\nWe’re changing that.\nWe build mobile-first business software that feels like a consumer app, runs on AI, and spreads like a creator brand.\nOur first product, Allo, gives you a second number on your phone, answers missed calls with AI, transcribes everything, and syncs it to your CRM.\nOver 20,000 businesses use it every day.\nNext up: expenses, invoicing, and more.\nWe’ve raised +15 million dolars from Base10, Lightspeed, EMBLEM, and 30+ top operators.\nOur team is based in Paris, Buenos Aires, Miami.\nMission\nDrive the evolution of our backend technology, infrastructure, and AI capabilities to ensure high performance, scalability, and seamless integration for our platform.\nWhat will you do\nWork closely with our CTO and engineering team to design and evolve the core backend and platform architecture that powers all our applications.\n\nMentor and support other engineers.\n\nLead complex technical initiatives across backend systems, data infrastructure, CI/CD pipelines, and developer tooling.\n\nDefine and implement scalable foundations that allow the team to ship faster and operate reliably as we grow.\n\nWhat you’ll be working on\nDesigning and evolving the backend architecture that powers our products and internal platform.\n\nBuilding scalable and reliable services.\n\nImproving infrastructure, observability, reliability, and deployment workflows across the engineering stack.\n\nWorking directly with cloud services (e.g., AWS, Supabase, Cloudflare).\n\nLeading technical decisions and helping the team scale operationally.\n\nWhat we’re looking for\nBackend Engineering\nStrong expertise in backend development with languages like Kotlin, Java, Go, Python, or similar.\n\nProven experience building and operating scalable backend systems in production.\n\nDeep understanding of distributed systems, reliability, and performance optimization.\n\nExperience integrating AI models or AI-powered workflows into real product systems is a strong plus.\n\nSystems Architecture\nStrong experience designing scalable architectures and making high-impact technical decisions.\n\nAbility to design systems that remain reliable, observable, and maintainable as the company scales.\n\nPlatform & Infrastructure\nExperience designing and improving developer platforms, CI/CD pipelines, or internal engineering tooling.\n\nStrong understanding of cloud infrastructure and production environments.\n\nExperience with monitoring and observability tools such as New Relic, Datadog or similar.\n\nHow you think\nYou care about why we build things, not just how.\n\nYou ask smart questions, challenge ideas when needed, and help shape what’s next.\n\nYou think in terms of user value and business impact.\n\nHow you work\nYou communicate clearly, give feedback with no ego, and help others grow.\n\nYou move fast, take ownership, and thrive in ambiguity.\n\nYou're comfortable working in English and in a small team with big goals.\n\nWhat matters to us\nYou’ve worked in product companies.\n\n7+ years of experience building and operating large-scale backend systems.\n\nExperience owning or influencing architecture decisions across teams.\n\nYou’re proactive, autonomous, and comfortable operating in early-stage startup environments.\n\nYou can communicate in English, since that’s our official language. Most of the team also speaks Spanish and French.\n\nWhat we offer\nCompetitive salary (in USD or local equivalent)\n\nEquity package\n\n10-day team retreats abroad every quarter\n\nTrips to our Hubs (Pairs/Miami/BA) for onboarding and more\n\nLaptop and work setup of your choice\n\nCoverage for private health insurance (for US or LATAM hires)\n\nA tight, ambitious team building something real - fast\n\nHow to apply\nClick the Apply button on this page to send your application.\nNo cover letter needed just tell us who you are and why this role fits you.\nWe welcome people from all backgrounds.\nIf you’re part of an underrepresented group in tech, we especially want to hear from you.","description_format":"text","description_chars":4103,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Spanish","level":"All levels","optional":false},{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Equity","Health insurance"],"hiring_locations":[{"name":"Argentina","iso":"AR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-05T13:13:33Z"},{"event":"open","at":"2026-09-26T01:33:43Z"},{"event":"close","at":"2026-11-02T17:16:24Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/the-mobile-first-company-staff-engineer-backend-platform","json_url":"https://alion.io/job/the-mobile-first-company-staff-engineer-backend-platform.json","meta":{"generated_at":"2026-11-03T01:11:49Z","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":1382,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":456099},"rest":"https://alion.io/mcp/rest/get_company?id=456099"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthe-mobile-first-company-staff-engineer-backend-platform"},{"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%2Fthe-mobile-first-company-staff-engineer-backend-platform"},{"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%2Fthe-mobile-first-company-staff-engineer-backend-platform"},{"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/the-mobile-first-company-staff-engineer-backend-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthe-mobile-first-company-staff-engineer-backend-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":275349}},{"tool":"search_jobs","arguments":{"company":"themobilefirstcompany.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":275349},"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.
