We are seeking a Lead / Principal Engineer (Developer) to build a new planning and simulation product from scratch. This is a hands-on technical leadership role with a strong focus on frontend engineering, combined with the full-stack capability to contribute to backend services and architectural ownership across UI, data-heavy workflows, and integrations with backend APIs.

You will work within a modern platform environment to deliver scalable, secure, and high-performance UI solutions, designing AI-first UI patterns that surface automated status updates and proactive suggestions rather than relying on manual, click-driven interactions. While experience in utilities or asset-intensive industries is valuable, the primary focus is on enterprise SaaS product development.

This role suits an engineer who wants to code, lead, and shape architecture — primarily on the frontend, with the range to work across the stack — while adopting AI-first and modern engineering practices, and who is comfortable working in a fast-evolving product environment where requirements are still being shaped.

What You'll Be Doing

Building the frontend for a new planning and simulation product from scratch, with a strong focus on frontend architecture and delivery.

Designing UI patterns for an AI-first workflow — surfacing automated status updates and proactive suggestions rather than manual click-driven interactions.

Working closely with backend, UX and product while requirements are still being shaped.

Handling large, data-heavy views (scheduling, capacity, simulation output) with a strong eye on performance.

Delivering end-to-end features, from UI through APIs to data and deployment, and contributing to backend services in Go where needed.

Building and maintaining enterprise integrations (internal/external systems, APIs, identity services).

Contributing to cloud-native architecture (containers, CI/CD, observability).

Working within and extending platform frameworks.

Providing technical leadership: architecture decisions, code reviews, mentoring, standards.

Ensuring quality, performance, security, and maintainability across the stack.

Collaborating closely with Product, UX, and cross-functional teams.
