As a Full Stack Developer, you will play a pivotal role in both frontend and backend development.

You will own features end-to-end, from product requirements through backend logic, API design, and frontend UI, on our ML/AI-based IRONSCALES platform. Collaborate with UI/UX Designers, Product Managers, and Software Engineers to deliver compelling user-facing products while owning deployment and optimization of production code.

Furthermore, you will join our growing R&D team and be part of shaping how we build, not just what we build. Beyond delivering features, you will help evolve our development culture: improving our SDLC, integrating AI-assisted workflows and tooling, and building the kind of engineering environment where great software ships faster and with higher quality.
