Our core product is the Theo Platform, a research environment built to help researchers iterate faster, validate rigorously, and reach verified results they can trust.\nWe're a fast-growing, remote-first team of builders, researchers, engineers, and thinkers working across Canada, the US, the UK, and expanding globally. What brings us together is a shared curiosity about how the universe works, and a belief that we can build systems that help us explore it more effectively.\nWe spend our time working on questions that don't have clear answers, like how to design AI that can reason through scientific problems, and how the scientific process as a whole might evolve. This is work that sits somewhere between creativity and rigorous thinking, and often requires comfort with ambiguity and iteration. If you're someone who enjoys tackling big, abstract problems and exploring ideas that don't yet have a defined path forward, you'll likely find the work here interesting.\nJob Description:\n FirstPrinciples is seeking skilled and motivated developers to join our team. In this role, you will play a crucial role in building technology tools to accelerate research in theoretical physics. You will work on developing our AI Physicist, leveraging gen AI tools like ChatGPT, and exploring and building new technologies to drive breakthroughs in theoretical physics.\nKey Responsibilities:\nContribute to the design and coding of the AI Physicist, a closed-loop research engine, including the development of tools to support hypotheses generation, peer review, physics based simulations, validation against experimental data and self-revision, among other things.\n\nWrite safe, testable code and set up automated unit tests to catch errors and apply lessons from recent research findings.\n\nExplore and integrate SOTA tools into existing platforms to enhance model capabilities. These tools can provide advanced analysis and insights, furthering the understanding of theoretical physics.\n\nAdd self-improvement features that pass automated checks before deployment.\n\nTrack runtime metrics and suggest optimizations that keep the project efficient and sustainable.\n\nDevelop custom tech solutions tailored to the specific needs of researchers. This may include developing algorithms, data analysis tools, or other software to accelerate research in specific areas of theoretical physics.\n\nApply knowledge of product development principles and practices to ensure that the tools developed are useful and effective for theoretical physicists worldwide.\n\nCollaborate with stakeholders to define requirements, prioritize features, and ensure successful delivery.\n\nQualifications:\n\nBachelor's or Master's degree in Computer Science, Engineering, or related field.\n\nExperience with common software architecture patterns and best practices.\n\nProven experience with web development and API integrations is essential.\n\nExcellent programming skills are a must.\n\nProficiency in gen AI tools and their applications (e.g., ChatGPT, AlphaCode, Claude) is necessary.\n\nStrong communication skills are crucial to articulate technical concepts to non-technical stakeholders.\n\nAbility to work independently and collaboratively in a fast-paced environment.\n\nKnowledge of theoretical physics or a strong interest in the field is a plus.\n\nFamiliarity with cloud technologies and infrastructure is a plus.\n\nA passion for advancing knowledge and science advocacy is highly desirable.\n\nApplication Process:\n\nInterested candidates are invited to submit their resume, a cover letter detailing their qualifications and vision for the role, and references. Please include “Member of Technical Staff, Engineering\" in the cover letter.\n\nJoin us at FirstPrinciples and be a part of a transformative journey where science drives progress and unlocks the potential of humanity.","description_format":"text","description_chars":3923,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Game Design","AI Research Labs","AI for Science"],"lifecycle":[{"event":"open","at":"2026-05-28T13:36:26Z"},{"event":"close","at":"2026-08-22T15:27:22Z"},{"event":"reopen","at":"2026-09-05T19:31:06Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.689,"p_room":0.28,"age_days":158,"expected_fill_days":77,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/firstprinciples-member-of-technical-staff-engineering","json_url":"https://alion.io/job/firstprinciples-member-of-technical-staff-engineering.json","meta":{"generated_at":"2026-11-03T07:04:14Z","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":9944,"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":6477},"rest":"https://alion.io/mcp/rest/get_company?id=6477"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffirstprinciples-member-of-technical-staff-engineering"},{"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%2Ffirstprinciples-member-of-technical-staff-engineering"},{"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%2Ffirstprinciples-member-of-technical-staff-engineering"},{"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/firstprinciples-member-of-technical-staff-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffirstprinciples-member-of-technical-staff-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":70016}},{"tool":"search_jobs","arguments":{"company":"firstprinciples.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":70016},"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.
