Wherever you're based, we'll connect you with your nearest office for onboarding, and fly you to join the full team for our quarterly \"Season Openers\" (we cover travel and accommodation). If you're relocating to join us, we can also assist with relocation costs.\nOur Story\nPartly is building the infrastructure for anyone to repair anything. We believe everything built should be repairable, and we're building frontier AI to put repair knowledge to work, starting with the $2tn automotive market.\nOur model, Interpreter, is the first AI purpose-built to understand repair. Trained on 1M+ car models and 1B+ parts, it reads a repair job the way an estimator does, resolves damage into the exact purchasable part, and shows its reasoning with a confidence score. On real production jobs, an estimator working with Interpreter reaches 98.8% parts-list accuracy, against 92.1% with today's tools. It powers PartlyRepair, used by collision shops, workshops and suppliers to take the admin off the job; PartlyLabs, the agentic infrastructure enterprises use to deploy Interpreter across their own workflows; and a developer API.\nFounded by ex-Rocket Lab engineers, we've raised a $50m Series B led by DST Global (Anthropic, Airbnb, Meta, TikTok, Spotify), with Blackbird Ventures, WNDR, Activant Capital, Icehouse Ventures, Square Peg, Airtree and Ecliptic Venture Capital. Hear it from the team: Why Partly exists and AI at Partly.\nThis role\nIn this role, you will work alongside other members of our development team to tackle hard, exciting problems and build beautiful software.\nWhat will you do\nYou'll be working on mission-critical systems for our core SaaS and API platform.\n\nYou will be ensuring these features are highly scalable, fault-tolerant and accurate.\n\nYou will be working to provide a great experience to businesses using the Partly platform.\n\nYou will be helping to develop and share software best practices with the team.\n\nThis is an opportunity to become an expert in the extremely complex and underserved auto parts domain.\n\nYour skills\n5+ years of experience developing complex applications\n\nFirmly grounded computer science and engineering fundamentals, including data structures, concurrency, architecture, APIs, testing, and design patterns.\n\nStrong written and verbal communication and collaboration skills\n\nStrong knowledge of databases and data models, relational and NoSQL\n\nExperience building reliable, distributed systems\n\n(Bonus) Experience with automotive parts\n\n(Bonus) Experience with Rust\n\nBenefits\nHealthy, Catered Lunches - Enjoy fresh, healthy lunches every workday in our Auckland, Christchurch, London, and Austin offices. With no meal prep needed, you can eat, connect, and refuel with your team. (And yes, snacks and drinks are always on hand.)\n\nHealthy Body, Healthy Mind - We care about performing at our peak. Every team member gets a $1,500 annual wellness allowance (or local equivalent) on a Partly-branded card. Use it on things such as gym memberships, rock climbing, physical therapy, massage, doctor visits, prescriptions-anything that you or your family need!\n\nFamily Comes First - Primary caregivers receive 3 months of fully paid parental leave, plus a flexible return-to-work plan (four days a week at full pay for your first three months back).\n\nWorkspaces That Inspire - Our brand-new, architecturally designed offices are built for collaboration and creativity, with great coffee, social spaces, and some of the best cafes just a few steps away.\n\nGetting Here Is On Us - If you commute to a Partly office or coworking space (atleast 4 days a week), choose from a paid 24/7 parking spot or a commuting allowance. One less thing to think about!\n\nOffice-First with Flexibility - In cities where we have an office (Christchurch, Auckland, London, and Austin), we default to working from the office every day. This lets us move faster, make better decisions, and build strong relationships. We also operate with a high-trust environment, so you can manage your time around your life and flex your schedule to do your best work.\n\nTime Off - you can use your annual leave and sick leave from day one, no waiting to accrue it first. And if you ever go into a negative balance, that's fine too, we trust you to manage your own time off\n\nWe Celebrate Together - From weekly happy hours and monthly lunches to quarterly season openers and an annual global offsite, we make time to connect, celebrate, and have fun as one team.\n\nGiving - We support charitable giving and will top up your donation by 33% for charities on the GiveWell list\n\nEquity - You'll receive share options (ESOP) with a 4-year vesting schedule and a 1-year cliff, true ownership in Partly from day one. Your strike price is a flat $0.01 per share, and you have up to 10 years to exercise.\n\nRelocation\nIf you're relocating to Partly HQ, whether from overseas or within the country, we offer a generous relocation allowance to help support your move.","description_format":"text","description_chars":5071,"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":["Annual leave","Equity","Gym membership","Parental leave","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["B2B Commerce","Automotive Software","Supply Chain & Logistics Software"],"lifecycle":[{"event":"open","at":"2026-10-13T21:09:36Z"}],"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":61,"reasons":["conf:2","win:early"],"computed_at":"2026-10-14T03:05:10Z"},"pay":null,"html_url":"https://alion.io/job/partly-principal-software-engineer","json_url":"https://alion.io/job/partly-principal-software-engineer.json","meta":{"generated_at":"2026-10-14T03:05:10Z","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":4776,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":364},"rest":"https://alion.io/mcp/rest/get_company?id=364"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpartly-principal-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%2Fpartly-principal-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%2Fpartly-principal-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/partly-principal-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpartly-principal-software-engineer"}]}
