We’re building a new generation of software systems where
AI is a core component of the architecture
, not an add-on. These systems combine backend services, intelligent automation, and data-driven decision layers to support complex user workflows at scale.
As a
Senior Software Engineer
, you’ll join a small, senior team responsible for designing and delivering robust, production-ready platforms. You’ll work on systems that integrate AI capabilities, backend services, and modern web applications, with a strong focus on reliability, scalability, and clean architecture. This project is
long-term.

Design and scale backend services using
TypeScript/Node.js
,
AWS
, and
Postgres

Build and evolve systems that integrate
AI-driven logic
, orchestration layers, and external data sources.
Develop secure and scalable data pipelines, applying best practices around privacy, access control, and observability.
Collaborate closely with product and design teams to deliver
end-to-end features
(backend and frontend).
Ensure systems are reliable, observable, and performant in production environments.
Contribute to technical decisions, code quality, and engineering standards within a small, high-impact team.
