And we’re just getting started! ## The Role As a Senior Full-Stack Engineer on the Media Team, you will be responsible for the cloud services that power Solink's media pipeline: ingesting, processing, storing, and serving media data at scale for over 36,000 customer locations. You'll work deep in AWS-native infrastructure, building services that are cost-efficient, observable, and resilient under real-world load. This role is ideal for a senior backend or full-stack engineer who thinks in terms of throughput, latency, and cost per gigabyte as much as they think in code; someone who is comfortable owning a service from design through production operation, and who treats reliability and resource efficiency as first-class design constraints rather than afterthoughts. ## What You'll Do - Design, build, and operate backend services that handle media ingestion, processing, storage, and retrieval at scale. - Work extensively with core AWS services (SQS, S3, Lambda, and related managed services) to build event-driven, loosely coupled pipelines. - Leverage AI tools effectively throughout the development lifecycle, from planning, design, implementation to operation, debugging and observability. - Design and evolve media platform APIs and contracts for multiple internal, as well as external consumers with contract and end-to-end tests. - Instrument services with meaningful observability: structured logging, metrics, and traces built on OpenTelemetry concepts, so behaviour in production is understandable regardless of the underlying vendor (Datadog, Grafana, Honeycomb, or otherwise). - Own the full deployment lifecycle for your services: staging and production environments, gradual roll-outs, canary releases, and A/B testing of infrastructure and feature changes. - Continuously monitor and tune and optimize cloud resource usage (networking, storage tiering, and compute/processing), balancing cost, performance, and reliability trade-offs. - Diagnose and resolve complex, cross-service production issues, including intermittent and load-dependent failures in media pipelines. - Partner closely with Product, QA, and cross-functional engineering teams to translate media and storage requirements into pragmatic, production-ready services. - Contribute to architectural decisions for the media platform, including service boundaries, data models, and integration contracts with other teams. - Mentor other engineers through code reviews, design discussions, and informal knowledge sharing. - Continuously improve team tooling, run books, 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 backend or backend-leaning full-stack engineer, with a track record of owning production services end-to-end for low-latency massive volume data. - Hands-on cloud and AWS experience, with proficiency in core services such as SQS, EKS, Redis, and CloudFront alongside S3/Lambda and a solid grasp of designing around their operational characteristics and limits. - Strong AI tool usage to increase quality and velocity, and a learning mindset that helps evolve development workflow as AI tooling and capabilities change. - Observability experience, not tied to any specific vendor, but a strong conceptual understanding of OpenTelemetry (traces, metrics, logs) and how to use it to make distributed systems debuggable. - Practical experience with cloud deployment practices: managing staging and production environments, running gradual/canary roll-outs, and conducting A/B tests on infrastructure or service changes. - A resource-aware, optimization-oriented mindset: comfortable fine-tuning cloud networking, storage configuration, and processing pipelines to balance cost, performance, and reliability. - Strong distributed systems fundamentals: asynchronous processing, eventual consistency, idempotency, and failure handling in multi-service pipelines. - Experience with modern backend development, including API design and production reliability practices. - Comfortable diagnosing complex, cross-service, and intermittent production issues independently and under pressure. - Strong problem-solving skills, an ownership mindset, and the ability to influence technical decisions beyond your own code. - Comfortable improving and extending legacy, brownfield services. ### Nice-to-Have - Experience with media, video, or other high-throughput binary data pipelines and technologies (e.g. WebRTC, HLS, RTSP, ffmpeg). - Experience with Kubernetes and cloud-native operations (observability, metrics/tracing, incident response, SLOs). - Experience with GCP and Azure - Experience with TypeScript and Rust - Experience scaling systems in high-growth or "next-stage" environments. - Interest in applying AI/ML 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. ## Our Values We do things the Solink way: - Act with URGENCY – Our customers move fast, so we do too. - Deliver with QUALITY – We sweat the details and hold a high bar. - Win with TEAM – No egos. Just outcomes, built together. - Lead with TRUST – We earn it through clarity, consistency, and care. These aren’t just words—they shape how we hire, lead, and grow. ## Why Solink? We’re not just building tech - we’re building a place where great people do great work. - Clarity and trust: Where the role allows, we support flexibility in how and where work gets done - and we’re upfront about what’s required. - Meaningful equity: Every full-time, permanent employee has a stake in our growth. - Comprehensive benefits: Fully paid health & dental (no waiting period) + $500 health spending account. - Wellness support: Monthly reimbursement for fitness, wellness, or mental health programs. - Growth through merit: Advancement is based on contribution, initiative, and the ability to raise the bar - together. - Candid culture: Clear expectations, honest feedback, and no politics. - Social connection: From So-learns to Solink-o and So-lunches, we stay connected in ways that actually feel fun. ## What to Expect from the Hiring Process We respect your time and value transparency.
