Engineering stays in-house on a modern stack, with a proprietary AI layer on top that is moving from pilot to core capability. Several internal tools are being consolidated into a single platform. They take AI-assisted development seriously and with discipline, and want senior engineers who know where it helps and where it needs a human check.\nThe Role\nWe are seeking a Senior Software Developer to join a growing team in Christchurch. You will be the person other developers turn to for the hard calls: how to design an integration, how to structure an agent, whether a piece of generated code is safe to ship. The role is hands-on and backend-focused, with real influence on engineering practice at a time when AI is changing both the speed of delivery and the volume of code to review.\nWhat You'll Be Doing\nDesigning and building backend services and APIs in C# and .NET behind AI agents, conversational tools and automation across several business units\nMaking design decisions on how new AI features sit within a complex, integration-heavy platform\nBuilding on an in-house language model and modern tools\nOwning review standards for AI-generated code, including manual first reviews, and helping the team catch what AI tends to get wrong, such as inefficient queries and database locking\nCoaching mid-level developers and lifting the capability of the wider team\nWorking with analysts and business leaders to separate genuinely valuable AI use cases from merely exciting ones\nBalancing new feature delivery with keeping the existing estate healthy, with realistic estimates\nSkills and Experience We're Looking For\n5+ years' commercial experience in C# and .NET, with a record of senior ownership\nDeep SQL Server knowledge, including performance tuning\nCloud experience\nPractical AI delivery, such as LLM APIs, agents or AI-enabled products shipped to production, with examples that hold up under technical questioning\nA track record of mentoring and rigorous code review\nStrong communication skills, including explaining trade-offs to non-technical stakeholders\nExperience in integration-heavy systems is advantageous\nThis position is based in Christchurch. If you're a senior developer who wants to apply AI properly on a complex, real platform and help set the standard for how a team builds with it, please apply now.","description_format":"text","description_chars":2521,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-16T05:18:16Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":24,"reasons":["conf:0","win:early"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/walker-smith-senior-software-developer","json_url":"https://alion.io/job/walker-smith-senior-software-developer.json","meta":{"generated_at":"2026-10-16T14:30:18Z","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":14085,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":4423671},"rest":"https://alion.io/mcp/rest/get_company?id=4423671"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwalker-smith-senior-software-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%2Fwalker-smith-senior-software-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%2Fwalker-smith-senior-software-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/walker-smith-senior-software-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwalker-smith-senior-software-developer"}]}
