ZOLEO is building the next generation of connected communication devices — integrating hardware, firmware, mobile applications, and cloud services into one seamless global experience. We design technology that keeps people connected when it matters most, combining satellite and cellular networks into a reliable, global messaging ecosystem. Our products are trusted by adventurers, remote workers, and emergency responders around the world.

We’re driven by the challenge of bridging the gap between devices, apps, and cloud services to create a truly unified user experience — one that works anywhere. The ZOLEO Web platform is how thousands of users manage accounts, configure devices, and stay connected from any browser. It’s also the foundation for partner and enterprise integrations — enabling device monitoring, remote control, and custom integrations into the ZOLEO ecosystem.

As the platform grows, it must remain fast, reliable, and intuitive across everything from account management to real‑time device tracking and partner‑facing tools. You’ll help shape the experience customers and partners depend on to stay connected anywhere. As a Senior Software Engineer, you’ll lead technically significant initiatives across the stack — building React interfaces, Node.js services, and PostgreSQL‑backed systems.

You’ll work closely with product and design to deliver production‑ready solutions, solve complex architectural problems, and raise the engineering bar through technical leadership and execution. This is an AI‑first engineering environment. Tools like Cursor, Claude Code, and agentic workflows are core to how we build, test, and iterate.

You’ll be expected to use them fluently, help evolve team practices, and enable others to get the most value from them. Your work ships to a global user base that depends on ZOLEO in some of the most challenging environments on earth. The features you lead and the performance improvements you drive will have direct, measurable impact on how customers stay connected.

You'll work across the entire stack — building responsive, accessible React UIs, developing Node.js APIs, and designing PostgreSQL schemas, and strengthening infrastructure resiliency.



An AI‑First Engineering Culture. You'll work in an environment where AI‑assisted development is the norm, not the exception.

You'll go beyond autocomplete — using AI for scaffolding, debugging, testing, and exploration — and help define the patterns the team adopts. You'll work alongside senior and staff‑level engineers who care about craft, and you'll have room to deepen your expertise in React, distributed systems, and cloud‑native development in a low‑bureaucracy environment where positive ideas win on merit. As a senior engineer, you'll also help grow the engineers around you.

We emphasize thoughtful design, code reviews, testing, and shared ownership — and we expect senior engineers to set the standard.

Build

Polished, Performant Web Experiences. Lead the development of React interfaces that are fast, accessible, and intuitive. Design and build resilient backend services in TypeScript and Node.js (Express), leveraging AWS services like SQS, Lambda, ECS, S3, and Temporal.

You'll also shape the PostgreSQL schemas and queries behind them — efficient, well‑indexed, and built to grow. Architect and operate services on AWS, using CDK to define infrastructure as code so environments stay repeatable, version‑controlled, and easy to evolve as the platform scales.

Ship With

Confidence. Practice test‑driven development, write meaningful automated tests, and shape the CI/CD pipelines that make production safe to ship to. Code With AI, Not Just With a Keyboard. Use agentic AI tools as a core part of your workflow — for scaffolding, generating tests, exploring approaches, and accelerating iteration.

You'll help define and evolve the AI‑assisted practices the team adopts. Work closely with Product, Design, and other engineering teams to turn requirements into well‑shaped solutions,



and bring non‑engineers along on the technical decisions that matter. AI‑First Mindset.

You actively use AI coding tools — Copilot, Cursor, agentic workflows — and see them as force multipliers, not shortcuts. You're curious about how to push these tools further, and you bring others along by sharing the patterns and practices that work. You bring 7+ years of professional software engineering experience with deep expertise in TypeScript, React, and Node.js/Express.

You understand how frontend and backend fit together, and you've owned complex features end to end in production. Deep React & UI Expertise. You have a strong eye for building well‑architected, responsive, and accessible React applications at scale.

You're fluent in modern React patterns — hooks, context, component composition — and you make sound trade‑offs around performance, state management, and user experience. You have hands‑on experience designing resilient backend services in TypeScript and Node.js, and you're comfortable working with AWS services like SQS, ECS, and S3, as well as workflow tools like Temporal. You've contributed to CI/CD pipelines and care about delivering software that's stable, efficient, and measurable in production.

Solid Data

Skills. You have substantial experience with PostgreSQL (or similar relational databases) — writing and tuning complex queries, designing schemas that hold up over time, and reasoning about data integrity and performance under load. You communicate with clarity and purpose, especially when navigating technical decisions with non‑engineers.

You thrive in environments where engineering and product work closely together, and you treat code reviews, feedback loops, and shared ownership as how great software gets built. 160,000 - $185,000 CAD base salary.

Flexible

Work. Health, dental, and flexible spending accounts tailored to your needs. Vacation and sick days to help you rest, recharge, and stay well. Our recruitment process may use artificial intelligence tools, alongside human review, to assist with the screening or assessment of candidates. We are currently hiring for this role and welcome candidates from all backgrounds and experiences.
