Proxxi builds life-saving technology for the world's most dangerous jobs. Our flagship product, the Voltage wearable, protects thousands of frontline workers from electrical hazards — and recently won Best Product at the 2025 IEEE Electrical Safety Workshop. We're scaling fast, bringing new safety technologies to market across construction, manufacturing, and utilities.

When you ship code here, it reaches real people doing real high-risk work. We move fast, care deeply, and build things that matter.

The role

This is a maker-leader role — 75% high-impact coding, 25% technical leadership. You'll own our mobile and back-end platform, set the technical direction for the team, and directly manage and mentor three developers. Our CTO currently fills this role; this hire frees them to focus on hardware, firmware, and strategic growth.

You are not a manager who used to code. You are a strong developer who also leads — and leads by example.

What you'll do

• Lead mobile development across iOS (Swift) and Android (Kotlin), setting quality and architectural standards.
• Own back-end infrastructure: API design, cloud architecture, DevOps practices, and reliability.
• Manage and grow two developers — setting clear direction, conducting code reviews, and actively mentoring.
• Collaborate directly with our CTO on architectural decisions across the full stack.
• Identify technical risk early and drive solutions that balance speed and long-term quality.
• Establish and enforce engineering best practices across the team.

Tech stack

Mobile: Swift (iOS), Kotlin (Android)

Back-end: Node.js, Express, TypeScript

Cloud: AWS (EKS, EC2, RDS, S3), Kubernetes, Helm, Terraform, Docker

Database: PostgreSQL

Front-end: React, TypeScript

Internal tools: Retool, Python

What we're looking for

• 7+ years of development experience, with meaningful time in mobile (iOS or Android) and back-end/cloud work.
• Strong hands-on experience with Swift or Kotlin — you write production mobile code, not just oversee it.
• Solid back-end and DevOps chops: Node.js, TypeScript, AWS, CI/CD, containerization.
• Experience leading or mentoring developers — not just technically, but as a people-grower.
• High autonomy, high accountability. You identify problems before they're problems.
• You communicate clearly and write code that others can learn from.

Bonus points

• Experience with real-time event-driven systems
• Familiarity with IoT, industrial hardware, or connected device ecosystems.
• Data privacy, security, or GDPR experience.

Compensation & benefits

$180,000–$240,000 CAD · commensurate with demonstrated performance

ESOP: up to 0.5% equity · Comprehensive health benefits · Unlimited responsible vacation

How to apply

Start your application with the word Voltage. Then share a link to a project or repo you've shipped and are proud of — and tell us in two sentences why. Applications without both will not be reviewed.
