Now we’re reimagining how small businesses get paid and how money moves. We're making a critical, multi-year investment in two connected engineering portfolios, Payments Products & Experiences and Payments Platform, and we're hiring a Principal Engineer for each. As our three-year payments strategy reaches a turning point, you'll help shape what comes next, with domain-level influence over the next two to three years.\nYou'll shape technical strategy across multiple teams, partnering with senior stakeholders to turn complex requirements into scalable, resilient systems. Staying close to the technical detail, you'll set the example for a portfolio of 40 to 50 engineers. You'll also join a global community of Principal Engineers across Xero, driving engineering standards, architecture, and best practices.\nYou'll Go Bold by setting long-term direction, and Go Together by bringing product, engineering and senior stakeholders with you.\nThe teams\nPayments Products & Experiences: this portfolio is made up of our Get Paid and Growth teams, builds the checkout, payment methods, flexible payments and AI payment agents that help small businesses get paid on time.\nPayments Platform: this portfolio is the engine underneath, with provider integrations, bill payments and a single, product-agnostic API that other Xero teams build on.\nTogether they move billions of dollars across more than 150,000 transactions a day, a number set to double as we grow into the UK and US.\nThe teams are currently working on\nTech stack: microservices across web, API and data layers, built in languages such as C#, Java, Go or C++, running on AWS with SQL and NoSQL data stores.\n\nCurrent focus: reviewing existing payments systems to work out what to extend, migrate or rebuild, alongside Growth experiments and AI-powered payment chasing.\n\nFuture focus: a multi-year payments architecture covering agentic payment workflows, payments inside AI assistants and recurring payments.\n\nGlobal scale: replatforming payment methods and designing global rails and a ledger ready for new markets.\n\nWhere and how you can work\nYou'll be based in Sydney or Melbourne, working a hybrid model that blends time together in our modern offices with the flexibility of working from home. Boost days bring teams together to connect and collaborate in person. With colleagues across Australia and the US and payment flows that run around the clock, you'll also work across time zones.\nSome of the things we're looking for\nYou bring deep experience designing and running large-scale distributed systems in production, balancing reliability, performance and cost, and any payments or fintech experience is a real plus.\n\nAPI-first thinking is second nature, and you're at home across web, API and data layers, with fluency in at least one modern backend language, SQL and NoSQL stores, and cloud-native platforms, ideally AWS.\n\nLegacy-heavy systems are a puzzle you enjoy, and you make clear, practical calls on whether to extend, migrate or build while staying hands-on through pairing, spikes and code.\n\nA strong interest in utilising AI tooling is essential, as you will model how to use these technologies to automate tasks and improve engineering outcomes.\n\nYour background shows a deep curiosity for growth hacking and a proven ability to design and analyse A/B tests that drive product usage.\n\nYou'll Go Further by mentoring Staff and Senior engineers, shaping cross-team initiatives with Xero's Principal community and setting standards that lift engineering across Xero.\n\nApply even if your experience isn't a perfect match! At Xero, we hire based on your skills, passion, and the unique perspective you can bring to enhance our culture and team.","description_format":"text","description_chars":3765,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Australia","iso":"AU","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["HR & Payroll Software","Accounting & Tax Software"],"lifecycle":[{"event":"open","at":"2026-10-20T07:25:29Z"}],"visa":[],"liveness":{"score":57,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":0.9,"age_days":13,"expected_fill_days":33,"reasons":["conf:3","stale_co","velocity","win:mid"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/xero-principal-engineer-payments-products-platform","json_url":"https://alion.io/job/xero-principal-engineer-payments-products-platform.json","meta":{"generated_at":"2026-11-03T19:40:57Z","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":1996,"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":5206},"rest":"https://alion.io/mcp/rest/get_company?id=5206"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxero-principal-engineer-payments-products-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%2Fxero-principal-engineer-payments-products-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%2Fxero-principal-engineer-payments-products-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/xero-principal-engineer-payments-products-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxero-principal-engineer-payments-products-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2904332}},{"tool":"search_jobs","arguments":{"company":"xero.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2904332},"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.
