Equity Based Software Engineer

Compensation: We want to be direct about this before you read any further, because it is the biggest thing that determines whether this role is right for you. This role is equity, not salary. We are heavily bootstrapped and intend to stay that way as long as we can, which means we are asking you to take the bet with us rather than draw a paycheck early. Here is how it works. We start with a trial period of a few months so both sides can be sure it is the right fit. At the end of it, if we both want to keep building together, you come on as a co-founder with a meaningful equity stake. To be equally clear on the other side of that: once we are generating revenue and profitability, compensation gets discussed and distributed. This is not a permanent arrangement, it is the stage we are at. About the job: Lumira is an early-stage startup taking on a problem that has held K-12 back for years. School districts are sitting on mountains of student data, but it is scattered across systems that do not talk to each other, and the people who need it most, teachers and administrators, rarely get it in a form they can actually use. We are building an AI-native platform that brings all of that together and turns it into something educators can act on, so they can spend less time wrestling with their tools and more time helping kids. This is a co-founding opportunity, not a typical job posting. You would be getting in at the very beginning, building the product side by side with the founders, shaping the culture and the company as much as the code, and holding a real co-founder's stake in what we create together. Because a large part of the platform depends on pulling data cleanly from the systems districts already use, deep and proven API and integration experience is the most important thing we are looking for. Time commitment: We do not have a set number of hours we expect, and we are not measuring this like a traditional job. Everyone on the founding team approaches this with a co-founder mindset, and we trust each person to put in the time and effort they feel is necessary to build something great. Primary Responsibilites: Design, build, and own the API and integration layer that connects Lumira to school data systems (SIS and LMS) over REST and education standards like OneRoster, so district data flows in cleanly, reliably, and at scale. This is the core of the role.Build and ship full-stack features using TypeScript, React, and Next.js on the front end and a serverless Node API layer on the back end, with a high bar for quality and performance.Architect and extend our multi-tenant data platform on Supabase and PostgreSQL, using Row-Level Security to guarantee tenant isolation and data integrity as we scale to many districts.Build AI-native features on top of large language models, including tool and function-calling agents, streaming responses, and safe, evidence-grounded outputs.Own quality across the lifecycle by writing tests, reviewing code, and managing CI/CD on Vercel for fast, dependable releases.Craft responsive, accessible interfaces with React and Tailwind that make complex district data feel simple and trustworthy for educators.Build security and privacy in from the start, applying role and attribute-based access control, careful PII handling, and FERPA-aligned practices to everything you ship.Help shape technical strategy, hiring, and product direction as a founding member of the team. Qualifications: Extensive, proven experience designing, building, and integrating APIs, including connecting to third-party systems over REST and webhooks, handling authentication, rate limits, retries, and messy real-world data, and building integrations that stay reliable in production. This is a core requirement for the role.Proven full-stack engineering experience shipping production web applications, with deep proficiency in TypeScript and modern React.Strong backend and data skills, including designing PostgreSQL schemas, writing efficient queries, and building secure multi-tenant systems.Hands-on experience building on large language models or AI APIs, including function and tool calling, streaming, and handling model output responsibly.Comfort with cloud deployment and CI/CD, ideally on Vercel, along with strong Git and GitHub workflows and automated testing.A solid grasp of system design for building maintainable, scalable services, and strong security instincts around access control, data privacy, and protecting sensitive student data.Self-directed and effective owning features end to end in a small, fast-moving startup where you set your own standard and carry real responsibility.Experience with education data standards like OneRoster, or with SIS and LMS integrations.Experience with Next.js and the App Router.Experience with Supabase and Row-Level Security for multi-tenant data isolation.Familiarity with FERPA-aligned practices and handling sensitive student data.Prior startup or founding experience, and a desire to build a company, not just a product. Why this matters: We are not just hiring an engineer, we are looking for a partner who wants to build something that matters. If you love the product, care about the schools and students it serves, and want a real hand in shaping the company from the ground up, we would like to hear from you.
