Our cloud-based platform integrates seamlessly with your existing cameras and systems, turning them into intelligent sensors that detect and interpret key moments. This empowers teams to make data-driven decisions, enhance security, and improve operational efficiency.

Trusted by over 30,000 locations across 32+ countries - including brands like McDonald’s and JYSK - Solink delivers clarity when it counts. Our solutions help businesses reduce shrink, optimize performance, and respond proactively to potential threats.

We're growing rapidly, earning industry recognition, and scaling with purpose. We’ve been recognized by Deloitte’s Fast 50™ and Fast 500™, Business Intelligence Group, and as one of Ottawa’s Best Places to Work. And we’re just getting started!

About the Role

As a Senior Full-Stack Engineer on the Core Apps – Video Team, you will play a key role in building and evolving Solink’s Video Management System (VMS) and cloud video platform—from camera/stream integration to customer-facing video experiences like live viewing, playback, investigation workflows, and exports.

This role is ideal for a senior engineer who is comfortable working across the stack, has strong backend and systems intuition, and can influence technical direction beyond individual tickets. You will help shape architecture, mentor teammates, and ensure our video platform scales reliably and efficiently as Solink grows.

Storage efficiency and video encoding/decoding are central to this role—we’re looking for someone who understands the real-world tradeoffs between cost, quality, reliability, and performance in large-scale video systems.

What You’ll Do

• Design, build, and maintain full-stack features across Solink’s video applications, with a strong emphasis on backend services and systems integration (roughly 60–70% backend).

• Build and evolve core video capabilities including:

  • Stream lifecycle management (camera connectivity, health, state)

  • Live and recorded video playback experiences

  • Video export/clip generation workflows

  • Investigation/search experiences that depend on fast, reliable video retrieval

• Develop and optimize backend services and APIs that support video workflows across edge and cloud environments.

• Work closely with edge and cloud components, including Linux-based edge devices and cloud services, to ensure end-to-end reliability.

• Improve storage efficiency and cost-performance of video workflows (retention, packaging, transcoding/processing strategies, and operational visibility).

• Contribute to design decisions balancing scalability, performance, reliability, security, and developer experience.

• Partner closely with Product, QA, and cross-functional engineering teams to translate requirements into pragmatic, production-ready solutions.

• Mentor and influence other engineers through code reviews, design discussions, and informal knowledge sharing.

• Continuously improve team tooling, observability, and processes, including thoughtful adoption of AI-assisted workflows where appropriate.

What We’re Looking For

Must-Have Qualifications

• Strong experience as a senior-level full-stack or backend-leaning engineer, with the ability to contribute across frontend, backend, and infrastructure layers.

• Proficiency with modern web development, including JavaScript/TypeScript and React (or similar frontend frameworks).

• Deep backend experience (Node.js or similar), including API design, distributed systems fundamentals, and production reliability.

• VMS / video surveillance domain experience (camera systems, VMS concepts, video workflows, and operational expectations).

• Strong hands-on experience with video streaming technologies we use today:

  • RTSP

  • HLS

  • WebRTC

• Practical experience with FFmpeg in production contexts (debugging pipelines, packaging/transcoding workflows, or integrating video processing into services).

• Strong understanding of video encoding/decoding fundamentals and the tradeoffs that impact:

  • storage footprint and cost

  • quality and latency

  • playback compatibility and seek performance

• Experience working in Linux environments, ideally including edge-device or performance/IO-sensitive systems.

• Comfortable working in a codebase that includes C++ and/or Rust (you don’t need to be an expert in both, but you should be able to navigate, debug, and ship in systems-language-adjacent areas when needed).

• Hands-on experience with cloud platforms (AWS preferred) and modern deployment patterns (infrastructure as code, CI/CD, containers/serverless—whatever fits your background).

• Experience with video storage/retention strategies at scale (tiering, lifecycle policies, segment management, compaction/repacking, etc.).

• Familiarity with hardware acceleration and performance tuning for video workloads.

• Strong problem-solving skills, ownership mindset, and ability to influence technical decisions beyond your own code.

Nice-to-Have

• Experience with Kubernetes and cloud-native operations (observability, metrics/tracing, incident response, SLOs).

• Experience scaling systems in high-growth or “next-stage” environments.

• Interest in applying AI/ML or AI-assisted development techniques to improve product capabilities and team productivity.

Security Requirements

• Candidates must undergo a criminal records check upon hire;

• Be a Canadian Citizen (dual citizens included), or eligible to work in Canada;

• Be willing to comply with Solink’s own security policies and standards.
