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.
