We've seen firsthand how data helps bridge art and science to create delightful experiences, impactful insights, and seamless automation. We're an early-stage, venture-backed company on a mission to get data out of specialized silos and adopted across all facets of a company. We're building a new kind of data platform that enables all developers, not just data specialists, to easily create and scale delightful data-intensive experiences.\nWe’re experienced founders with a track record of success. We have a remote-first team, are backed by incredible investors, and are building a high-performance culture that’s flexible and works well for working parents.\n A note about our job descriptions. We’ve written many JDs in our careers and wanted to try something new. We believe that everyone on the team deserves to have a great relationship with their manager. Our hiring managers write their job posts, choose their words intentionally, and use this as an opportunity to open up a dialogue.\nThe role\nYou will join the existing engineering team and split your time between two products: the open-source framework Moose and its hosting platform Boréal. As this is still very early in the company's life and the framework, you will have opportunities to stretch all across the stack, Whether on the Front End of the hosting platform, the backend, or the open-source framework itself.\nWhat to expect from me\nI am both a player and a coach for the team of engineers. I roll up my sleeves and care a lot about my craft. I am pragmatic, I spend myinnovation chips deliberately and will encourage you to do the same. I love learning, and I am always eager to read about the latest trends and best practices. I firmly believe that engineering is a team sport; the best technical architectures and designs come out of tight collaborations between team members. I will challenge your designs, encourage you to hone your craft, expect you to ship code to production often, and eventually expect you to coach more junior engineers as the team grows.\nWhat to expect from your peers\nAs a senior engineer on the team, you will collaborate closely with the product, design, and the rest of the engineering team to get Moose and Boréal to the next stage of maturity of their lifecycle. This team of ambitious and pragmatic people cares about each other’s happiness. We all love the grind and the thrill of the early stages of a company. We come from different parts of the world and appreciate what our cultures and experiences bring to the table. Many of us are parents and hence build in flexibility to be there for our families. You can choose to leverage that flexibility in whichever ways work for you.\nResponsibilities:\nBuild, Maintain, and Operate the Boréal hosting platform and Moose open-source project with the team\nReview and contribute to other engineers' designs and code\nCollaborate with Product and Design to make the product come to life\nParticipate in the recruitment process\nMentor more junior team members\nRepresent the company at industry events and conferences\nQualifications:\nMust haves:\nAsync Rust Production Experience\nRobust architectural and design skills\nStrong ability to learn new skills.\nGood communication skills\nRobust coding skills in Typescript\nUndaunted by a fast-paced, entrepreneurial environment \nComfortable operating in ambiguity, building systems, and making sense of what others might consider chaos\nNice to haves:\nPython Experience\nNextJS Experience\nClickhouse Experience\nPixel perfect Web UI building\nData Engineering Exposure\nDeveloper Tools Building Experience\nIf you're looking for a challenging role and are excited to build a company from the ground up, please apply!","description_format":"text","description_chars":3784,"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":"United States","iso":"US","kind":"country"},{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","AI Evaluation & Observability"],"lifecycle":[{"event":"open","at":"2026-09-12T10:36:39Z"},{"event":"open","at":"2026-09-26T08:54:45Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.204,"p_room":0.28,"age_days":777,"expected_fill_days":35,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/514-senior-software-engineer","json_url":"https://alion.io/job/514-senior-software-engineer.json","meta":{"generated_at":"2026-10-31T20:01:02Z","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":31390,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":11202},"rest":"https://alion.io/mcp/rest/get_company?id=11202"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2F514-senior-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%2F514-senior-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%2F514-senior-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/514-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2F514-senior-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":812899}},{"tool":"search_jobs","arguments":{"company":"514.ax","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":812899},"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.
