We’d love to hear from you.\nAbout Marsello\nMarsello is the Loyalty Marketing Platform that helps businesses grow loyal customers wherever they are. We serve over 2,000 brands globally, with teams in New Zealand, Canada and Australia and people contributing from around the world.\nThe role:\nOur engineering team works in an agentic way. Every engineer, at every level, orchestrates AI coding agents rather than writing every line by hand. Good work here comes from framing problems clearly, reviewing agent output carefully, and constantly improving how we build.\nAs a Full Stack Product Engineer, you’ll take features from a problem statement through to production. You’ll plan the work, brief agents on the parts they’re suited to, write the parts that need a human, and review everything carefully before it ships. You’ll work independently day to day and help shape how the team operates.\nWhat you’ll be doing:\nOwning features and platform work from problem to production\nReviewing agent-produced code with rigour, so we only ship work you’d be happy to stand behind\nTaking a regular turn on the product support rotation and turning what you learn into product improvements\nContributing to architecture and technical roadmap conversations\nImproving the prompts, evals, runbooks and tools the team relies on\nMentoring junior engineers through pairing, review and scoping\nWhat you’ll bring\n3-5+ years of software development experience in a SaaS environment\nStrong skills in the Microsoft .NET stack (C#, .NET Core, Web APIs) and MongoDB\nFrontend experience with HTML5, JavaScript and React\nConfidence working in AWS and Terraform\nFamiliarity with CI/CD and observability practices\nHands-on experience using AI coding agents (such as Claude, GitHub Copilot or Cursor) for real feature work, not just autocomplete\nA solid grasp of API integration and scalable system design\nClear communication with both technical and non-technical people\nCuriosity, initiative, and a drive to keep improving\nAt Marsello, you’ll have real ownership of meaningful features with direct customer impact, the chance to help define how an agentic engineering team works, and a collaborative, supportive team around you.\nWe also offer flexible working, subsidised Southern Cross Healthcare, Birthday Leave, Technology Allowance and a Wellness Allowance.\nWe’d love this role to be based in Wellington, alongside most of our engineering team, so it’s easy to collaborate in person.\nIf this sounds like you, apply now. We’d love to hear from you.","description_format":"text","description_chars":2689,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible schedule"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Loyalty Programs","Marketing & Sales AI"],"lifecycle":[{"event":"open","at":"2026-11-03T23:18:34Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":26,"reasons":["conf:1","win:early"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/marsello-developer","json_url":"https://alion.io/job/marsello-developer.json","meta":{"generated_at":"2026-11-05T21:54:31Z","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":2276,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":2351933},"rest":"https://alion.io/mcp/rest/get_company?id=2351933"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmarsello-developer"},{"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%2Fmarsello-developer"},{"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%2Fmarsello-developer"},{"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/marsello-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmarsello-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3711115}},{"tool":"search_jobs","arguments":{"company":"marsello.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3711115},"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.
