They are a valued participant whose data works for them, not against them, enriching their world and their own experience within it, with them retaining full control.\nOur mission is underpinned by proprietary, patent-pending technology built on a novel engine and system.\nThe Problem You Will Be Solving\nThe internet was built to inform the many, not to serve the individual. Platforms optimize for engagement, extraction, and consumption at global scale. AI has made this model even more efficient, with the user still largely remaining the input, not the full beneficiary.\nThe problem is not information. The world has never had more. The problem is that people give away a lifetime of data without receiving the personalized experience it should enable.\nPeople should not have to search. They should simply find.\nWho You Are\nHighly talented and motivated to build products with people, for people\n\nYou thrive in zero-to-one environments and find genuine satisfaction in creating from scratch\n\nA fast-paced thinker with a relentless desire to learn, improve, and raise the standard around you\n\nAble to inspire, elevate, and collaborate; you make the people around you better\n\nA great communicator; you express complex ideas with clarity, precision, and confidence across all levels of the organization\n\nAble to transform ideas into working systems and technical milestones with light speed and precision\n\nHighly ambitious and action-driven; you thrive under pressure and find genuine energy in working at the edge of what is considered possible\n\nCapable of designing and building production-grade systems in a fourth of the time most experienced and “sane” professionals would consider possible\n\nWhat You Will Do\nDesign and build the core API platform and integration framework with strong versioning, consistency, and deep awareness of production consumer dependencies\n\nBuild extensible third-party integration frameworks that connect external services across multiple domains through clean, unified interfaces\n\nDesign and build unified identity and profile systems that deliver consistent, real-time user state across the platform\n\nBuild high-reliability event streaming infrastructure as the backbone for real-time data flows, with strong guarantees around ordering, consumer management, and failure recovery\n\nImplement authentication and authorization infrastructure including OAuth 2.0, OIDC, fine-grained permissions, and secure multi-tenant access control suitable for consumer platforms with enterprise customers\n\nBuild enterprise integration layers with secure API surfaces and data exchange protocols that allow institutional customers to reliably embed platform capabilities into their own systems\n\nMinimum Qualifications\nMSc in Computer Science, Software Engineering or an equivalent degree\n\nDemonstrated experience originating distributed system architectures; you have designed systems, not implemented designs made by others\n\nProduction experience building APIs that multiple consumers depend on; with experience managing the operational consequences of that dependency\n\nDeep understanding of event-driven architecture and the consistency trade-offs inherent in distributed data synchronization\n\n3-5+ years of relevant experience\n\nPreferred Qualifications\nExperience with identity federation and secure multi-tenant system design at scale\n\nA track record of designing platform systems that other engineering teams depend on in production without requiring significant architectural revision\n\nDemonstrated track record of delivering reliable platform infrastructure faster than peers scope it\n\nWhat We Offer\nExpect the most talented, rigorous, and driven colleagues you have worked with; people who lift each other up and hold each other to the highest standard. This company is driven by ideas and innovation, regardless of age, position, or background. The best ideas must win and the people behind them recognized and rewarded.\nA home for exceptional people and geniuses within their domain; those who have always known what they are capable of and have been waiting for the environment to prove it to the world, whilst first being seen and supported by their coworkers.\nCompensation includes an attractive salary and meaningful equity ownership for an early-stage startup.\nEqual Opportunity\nWe are an equal opportunity employer committed to building an inclusive, high-performance culture where everyone can do their best work and reach their full potential. We welcome applicants of all backgrounds and do not discriminate on the basis of race, color, religion, national origin, gender, gender identity or expression, sexual orientation, age, disability, or any other characteristic protected by applicable law.\nApplication\nTo apply, send your CV/resume, LinkedIn profile, and a note on how and why you would like to contribute to our mission. Upon initial acceptance, an interview will follow shortly.\nPlease note that all applications and interviews are conducted in English. Fluency in written and spoken English is a requirement for all roles.\nAll applications are treated with strict confidentiality.","description_format":"text","description_chars":5392,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":true}]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-16T09:22:34Z"}],"visa":[],"liveness":{"score":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.652,"p_room":0.55,"age_days":32,"expected_fill_days":28,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/q-innovations-senior-backend-engineer-platform","json_url":"https://alion.io/job/q-innovations-senior-backend-engineer-platform.json","meta":{"generated_at":"2026-10-24T14:47:01Z","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":20892,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":4441675},"rest":"https://alion.io/mcp/rest/get_company?id=4441675"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fq-innovations-senior-backend-engineer-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%2Fq-innovations-senior-backend-engineer-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%2Fq-innovations-senior-backend-engineer-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/q-innovations-senior-backend-engineer-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fq-innovations-senior-backend-engineer-platform"}]}
