Senior Software Engineer

Who We Are

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.

Why This Role Matters

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.

What’s In It For You

• Real Users, Real Impact. 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.

• Full‑Stack Ownership. You'll work across the entire stack — building responsive, accessible React UIs, developing Node.js APIs, and designing PostgreSQL schemas, and strengthening infrastructure resiliency. You won't be siloed; you'll follow features from concept through to production.

• 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. We expect you to push the boundaries of what's possible with these tools and bring the rest of the team along with what you learn.

• Growth Through Collaboration. 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 good ideas win on merit. As a senior engineer, you'll also help grow the engineers around you.

• A Culture That Values Curiosity and Craftsmanship. We emphasize thoughtful design, code reviews, testing, and shared ownership — and we expect senior engineers to set the standard.

What You’ll Do

• Build Polished, Performant Web Experiences. Lead the development of React interfaces that are fast, accessible, and intuitive. You'll set the bar for component architecture, state management, and UI that feels right — not just UI that works.

• Build What Powers Connection. 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.

• Leverage Cloud‑Native Infrastructure. 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. You'll set the standard for code that's stable, observable, and measurable in production.

• 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.

• Collaborate Across the Product. 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.

What You Bring

• 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.

• Strong Full‑Stack Fundamentals. 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.

• Backend & Cloud‑Native 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.

• Distributed Systems Thinking. You've designed and operated distributed systems, and you reason fluently about the trade‑offs involved — consistency models, caching strategies, and event‑driven patterns. You can articulate why you made a given decision, not just what you built.

• 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.

• A Builder's Curiosity. You love to explore, question, and refine. You approach ambiguous problems by breaking them down, evaluating trade‑offs, and finding better ways forward. You're energized by learning and by raising the bar for the work around you.

• Collaboration That Counts. 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.

What We Offer

• Salary Range. $160,000 - $185,000 CAD base salary.

• Flexible Work. A hybrid model; balancing collaboration and lifestyle flexibility.

• Comprehensive Benefits. Health, dental, and flexible spending accounts tailored to your needs.

• Time to Recharge. Vacation and sick days to help you rest, recharge, and stay well.

• Growth Investment. A continuous learning environment backed by a professional development budget.

• Inclusive by Nature. A values‑driven workplace where diverse perspectives are celebrated.
