Role description

As a Senior Full Stack Engineer, you will be the primary driver of our web and mobile user experiences. You will focus on development of our Web platform, which serves as the core foundation for our iOS and Android applications. This role is about building highly responsive, mobile-optimized interfaces that feel native while being powered by a robust Go backend and REST APIs. You will collaborate closely with our Staff Engineer and CTO to bridge the gap between complex system data and intuitive user controls.

Technical Requirements

1. Web & Frontend Mastery

• 6–8+ Years of Software Experience: With a heavy focus on building sophisticated, data-rich web applications.
• Expertise in Angular: Mastery of the latest Angular versions. You should be deeply familiar with RxJS, state management, and building high-performance, modular components.
• Mobile-First Responsive Design: A "must-have" ability to create highly responsive, fluid interfaces that translate perfectly from a desktop browser to a mobile screen.

2. Backend & API Integration

• Go (Golang) Experience: Professional experience writing and maintaining Go code. You should be comfortable contributing to our backend services and ensuring the logic supports our frontend needs.
• REST API Design: Strong experience designing and consuming RESTful APIs. You understand how to structure endpoints for performance, security, and ease of use.
• SQL & Caching: Solid proficiency in SQL and experience working with caching layers to ensure a snappier user experience.
• Cloud Infrastructure (AWS): Familiarity with the AWS ecosystem and how to manage and deploy applications within a cloud environment.

3. Mobile (The Plus Factor)

• Hybrid Mobile Experience: Familiarity with Capacitor.js or similar frameworks to wrap web applications for mobile environments.
• Shipping to iOS/Android: Previous experience successfully shipping and maintaining apps in the Apple App Store or Google Play Store is a major plus.
• Fleet Control: Interest in building interfaces for MDM-managed iPads used as onsite control centers.

Key Responsibilities

• Web-to-Mobile Execution: Build and maintain the Angular web application that powers our browser experience and our native iOS/Android apps.
• API Development: Collaborate with the Staff Engineer to design and implement the Go-based REST APIs required to power new features.
• UI/UX Excellence: Ensure our interfaces are world-class in terms of responsiveness, performance, and accessibility.
• Staff-Level Partnership: Act as a high-level executor on architectural plans provided by the Staff Engineer, providing feedback and ensuring technical feasibility.
• Full-Stack Ownership: Take responsibility for features from the SQL query and Go logic through to the final pixel in the Angular view.

Nice-to-Haves (Training Provided)

• AI & Future Tech: Helping build our RAG-based AI agent and integrating LLM-driven features into the UI.
• Industrial IoT Protocols: Learning the basics of how our backend talks to BACnet, Modbus, and LoRaWAN hardware.
• Authorization Models: Familiarity with services like OpenFGA for fine-grained permissions.

The Full-Stack Profile

You are a "visual" engineer who cares deeply about the user experience but has the backend chops to ensure the "pipes" are working correctly. You enjoy the challenge of making a web app feel like a premium native experience on an iPad, and you are a proactive communicator who thrives in a collaborative environment alongside senior technical leadership.
