As an early team member, you’ll play a key role in shaping our platform, our culture, and the future of safety tech.


The Role

You’ll work across the full stack - from frontend experiences in Angular 19+ to backend services built on Supabase and .NET Core - to power the next generation of Helix EHS products.

This is a hands-on role where you’ll design, build, and ship features end-to-end, collaborating closely with product managers, designers, and fellow engineers to deliver solutions that delight our users and make workplaces safer worldwide.

* Develop complex form workflows and reusable UI components that drive data-rich user journeys
* Integrate frontends with backend services using Supabase and .NET Core APIs
* Design and maintain RESTful APIs, ensuring reliability, scalability, and security
* Work with PostgreSQL, optimising queries and schemas for performance
* Implement secure coding standards, RBAC, and multi-tenant architectures
* Participate in code reviews, CI/CD automation, and DevOps workflows via Azure DevOps
* Collaborate within agile teams using Git, Jira, and transparent delivery practices
* Deploy and monitor applications in Azure, ensuring stability and uptime
* Continuously improve our systems, performance, and developer experience


What You’ll Bring

* Strong experience as a full-stack engineer
* Deep expertise in Angular 19+, TypeScript, RxJS, and Reactive Forms
* Proven ability to design modular, reusable UI components
* Hands-on experience with Supabase and PostgreSQL
* Proficiency in .NET Core APIs and RESTful service design
* Strong understanding of secure coding practices, RBAC, and multi-tenant systems
* Familiarity with Azure DevOps, CI/CD pipelines, and Git workflows
* Comfort working in Azure cloud and agile environments
* Excellent communication, problem-solving, and collaboration skills
* Bachelor's degree in Computer Science, Software Engineering, or a related field


Nice to Have

* Experience in fast-paced start-up or scale-up environments
* Awareness of UI/UX best practices
* Experience within the EHS, SaaS, or enterprise software domains
* Understanding of ISO 27001, SOC 2, or other enterprise compliance standards


Why Join Helix EHS

* Shape a fast-growing SaaS platform that’s improving safety in critical industries
* Work with a modern, scalable tech stack
* Enjoy a collaborative culture, competitive compensation, and real ownership over your work
* Join a team that truly values quality, security, and user-centric design
