Senior Full-Stack Software Engineer; Next.js + Supabase + AI-Native

Senior Full-Stack Software Engineer (Next.js + Supabase + AI-Native)

United States or Canada

Finite State partners with product security teams, the guardians of our connected world, to create transparency for their connected devices and supply chains. Our platform handles connected devices and embedded systems across all industries, including those found in enterprises, healthcare, utilities, connected vehicles, manufacturing facilities, critical infrastructure, and government entities.

We are a fast‑growing series‑B company with a fully distributed workforce. Led by a team of seasoned experts, we are a mission‑driven team passionate about arming our customers with the actionable insights, critical vulnerability data, and remediation guidance necessary to mitigate product risk and protect the connected attack surface. We are committed to a remote‑first culture.

Join a mission‑driven team that’s securing the connected world. At Finite State, you’ll work alongside some of the brightest minds in cybersecurity and software supply chain analysis to uncover and mitigate vulnerabilities hidden in the firmware and software that power everything from cars to medical devices. Your work will have a direct impact on protecting critical infrastructure and shaping the future of IoT and device security — all within a flexible, fully remote culture that values innovation, craftsmanship, and measurable impact.

We’re looking for a Senior Full‑Stack Software Engineer with deep expertise in Next.js, Type Script, Postgre

SQL/Supabase, and AI‑assisted development to design, build, and deliver the scalable, secure systems behind our cybersecurity platform. This is a hands‑on, product‑focused role for an engineer who:

• Thrives at the intersection of secure software engineering, data‑heavy systems, and product innovation.
• Is fluent in AI tooling (Cursor, Devin, Copilot, etc.) and knows how to turn them into real velocity — not toys.
• Can design full‑stack solutions, think strategically about risk and performance, and help us move business logic closer to the data layer (Postgre
  
  SQL + Supabase).

You’ll work closely with product, design, and security researchers to create seamless, data‑driven experiences that empower our customers to secure the software supply chain.

• Full‑Stack Development: Build and maintain secure, scalable web applications using Next.js/React, Type Script, Node, backed by Postgre
  
  SQL on Supabase (and AWS RDS during migration). Own features end‑to‑end from UI to database.
• Database‑Centric Application Logic: Design and implement business logic close to the data using Postgres functions, views, triggers, Row‑Level Security (RLS), and Supabase Edge Functions, minimizing unnecessary middleware and enabling high performance and strong data isolation.
• AI‑Accelerated Development: Treat tools like Cursor, Devin, Git Hub Copilot, and agent frameworks as core parts of your workflow. Use them to scaffold and refactor full‑stack features, generate and evolve schemas, migrations, and RLS policies, and build internal agents that automate repetitive engineering tasks and glue systems together.
• Application Security First: Embed security best practices into every layer of development — from secure coding and dependency management to data protection and authentication/authorization (Supabase Auth, OAuth2/OIDC, SSO). Collaborate with security researchers to ensure features align with threat models.
• Product
  
  Collaboration:
  
  Work hand‑in‑hand with product managers and designers to translate customer pain points into impactful, intuitive features. Participate in product discovery and help shape roadmaps with a strong technical and data‑informed perspective.
• Architect & Scale: Design and optimize API contracts, edge endpoints, and event flows using Next.js (server components, API routes) and Supabase (Edge Functions, real‑time). Consider performance, resiliency, and multi‑region deployment (read replicas, data partitioning) as first‑class concerns.
• Data Expertise: Model and optimize relational data in Postgre
  
  SQL for large, multi‑tenant workloads. Own indexing strategies, query performance, and data…
