The only AI-native platform connecting backend operations with a forward-thinking storefront experience.\nBuilt for brands that want to sell anything - anywhere, Swap centralises global operations, powers intelligent workflows, and unlocks margin-protecting decisions with real-time data and capability. Our products span cross-border, tax, returns, demand planning, and our next-generation agentic storefront, giving merchants full transparency and the ability to act with confidence.\nAt Swap, we’re building a culture that values clarity, creativity, and shared ownership as we redefine how global commerce works.\nAbout the role\nOur agentic storefront is an AI shopping experience that helps shoppers discover, decide, and buy through natural conversation.\nAs a Staff Software Engineer, you’ll be a technical leader on the team building it. You’ll set direction for several engineering teams, take on the hardest cross-cutting problems, and stay hands-on in the code that matters most. You’ll work closely with Product, Design, Data, and engineering leadership to turn ambitious goals into practical plans, and you’ll help the engineers around you do their best work.\nResponsibilities\nLead large initiatives that run for several quarters and involve multiple teams, from first scoping through to production.\n\nWrite exemplar code in critical paths, setting the implementation bar for the wider group.\n\nReview important designs from other teams, helping engineers balance quality, speed, reliability, and long-term maintainability.\n\nDefine and uphold operational standards for the group: monitoring, availability, scalability, security, release safety, and cost awareness. Help lead serious incidents and follow through on the right fixes.\n\nLead tool evaluations and architecture migrations, making build-vs-buy trade-offs explicit.\n\nUse AI well beyond the basics, and push back on AI-generated complexity so code health holds as we speed up.\n\nOwn the business result of your work. Define success metrics, monitor after launch, and challenge constructively when something won’t move the needle for merchants.\n\nMentor Senior Engineers and below, and lead or join senior-level interviews.\n\nWrite and improve the documentation others rely on, such as architecture direction, decision records, and runbooks.\n\nRequirements\nSignificant experience (typically 8+ years) building and shipping production software, with a record of leading complex initiatives that cross team lines.\n\nDeep expertise in TypeScript/JavaScript and Node.js, including architecting REST and/or GraphQL APIs and distributed systems.\n\nComfort outside your home language and stack. We expect Staff engineers to be T-shaped.\n\nStrong relational database, data modelling, and SQL skills, plus familiarity with NoSQL.\n\nExperience designing for reliability and scale in the cloud, with solid CI/CD, observability, and incident-response practices.\n\nHands-on experience with LLMs or agentic systems, or a track record of picking up new technology fast and applying it sensibly.\n\nDaily use of AI coding tools, with a sense for when to trust them and when not to.\n\nExperience in eCommerce systems and platforms is preferred.\n\nExcellent written and verbal communication. You can explain trade-offs in business terms to any audience.\n\nA team player with a bias for ownership: you bring a solution along with the problem, and work isn’t done until it’s live and stable.\n\nWhat we offer\nCompetitive base salary: Pay that reflects your experience and the impact you’ll have, reviewed regularly as you grow with us.\nStock options: Own a piece of what we’re building. As a high-growth scale-up, you’ll share in the upside as the company grows.\nGenerous PTO: Competitive annual leave, with public holidays on top, plus your birthday off so you can celebrate properly.\nPrivate healthcare: Comprehensive private medical cover, so you can get the care you need quickly.\nPension contributions: Company contributions to help you build long-term financial security.\nWellness benefits: Support for your physical health and wellbeing, so you can look after yourself in the way that works for you.\nMental health support: Access to mental health resources and support, because looking after your mind matters as much as your body.\nEnhanced maternity and paternity leave: Extra support when you’re growing your family, so you can focus on what matters most.\nFlexible working: Choose how and where you do your best work, with the trust and autonomy to manage your own time.\nWork abroad for 4 weeks a year: Take your laptop somewhere new for up to four weeks each year, whether that’s family, travel, or a change of scenery.\nQuarterly team offsite budget: A dedicated budget each quarter for your team to get together, connect, and have fun.\nThursday happy hour: Wind down the week with your colleagues at our Thursday happy hour, held across all of our locations.\nBreakfast Mondays: Start the week with a good meal and good company.\nDiversity & Equal Opportunities:\nWe embrace diversity and equality in a serious way. We are committed to building a team with a variety of backgrounds, skills, and views. The more inclusive we are, the better our work will be. Creating a culture of equality isn't just the right thing to do; it's also the smart thing.","description_format":"text","description_chars":5355,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Flexible schedule","Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["E-commerce Platforms"],"lifecycle":[{"event":"open","at":"2026-10-19T11:08:34Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Senior or Specialist Worker, Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Global Business Mobility: Senior or Specialist Worker; Skilled Worker","cap_exempt":false,"checked_at":"2026-10-22T06:27:10+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":46,"reasons":["conf:1","win:early"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/swap-commerce-ltd-staff-software-engineer","json_url":"https://alion.io/job/swap-commerce-ltd-staff-software-engineer.json","meta":{"generated_at":"2026-10-22T14:20:01Z","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":13918,"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":1807561},"rest":"https://alion.io/mcp/rest/get_company?id=1807561"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fswap-commerce-ltd-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%2Fswap-commerce-ltd-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%2Fswap-commerce-ltd-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/swap-commerce-ltd-staff-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fswap-commerce-ltd-staff-software-engineer"}]}
