About Us:

Edgecom Energy is a purpose-driven clean-tech software company, delivering cutting-edge energy management solutions across Canada and rapidly scaling throughout North America. We empower some of the world’s largest energy users—including data centers, industrial facilities, and chemical processing plants—to reduce energy costs, cut emissions, and make measurable progress toward a sustainable future.
Our expertise spans demand response, distributed energy resource (DER) management, and advanced software tools that enable real-time decision-making for complex energy systems. We are also a Certified B Corporation, meeting rigorous standards of social and environmental performance, accountability, and transparency.
As we enter an exciting new phase of growth, we’re seeking driven, innovative professionals who are passionate about sustainability and eager to harness technology to combat climate change. Join a dynamic team of problem-solvers and trailblazers revolutionizing how businesses manage energy, improve efficiency, and protect the planet for future generations.
This is your opportunity to make a tangible impact—be part of something bigger.

What we offer:

Meaningful work with a purpose - reducing costs and emissions and saving energy for a more sustainable future.
Outstanding health, vision, and dental benefits.
A competitive and comprehensive compensation package.
A potential equity participation program aimed at extending ownership opportunities to employees.
A small agile team where you’ll be able to make a real-life difference.
Onsite Gym at the office
Hybrid Work
Personal days to promote work-life balance and employee well-being.

Responsibilities:

Write and review user stories, technical requirements, functional specifications, and test cases to ensure high-quality delivery across services and infrastructure.
Conduct thorough code reviews with a focus on reliability, maintainability, security, and adherence to DevOps best practices.
Build, maintain, and optimize CI/CD pipelines for automated testing, deployment, and environment provisioning.
Design and implement monitoring, logging, and alerting systems; continually measure system health and performance.
Investigate incidents by debugging, profiling services, and identifying performance bottlenecks across distributed systems.
Collaborate on infrastructure architecture, deployment strategies, containerization (Docker/Kubernetes), and cloud-native workflows.
Manage scalable backend systems with a focus on observability, resiliency, and fault tolerance.
Maintain and improve infrastructure-as-code, automation scripts, and operational runbooks.

Qualifications:

4+ years of experience engineering and reviewing backend systems built in Golang and Python.
Strong communication skills with the ability to collaborate effectively across DevOps, engineering teams, and external stakeholders.
Hands-on experience designing, deploying, and operating microservices architectures in production environments.
Solid understanding of time-series databases (InfluxDB, QuestDB) and relational databases (PostgreSQL), including performance tuning and operational monitoring.
Advanced experience with distributed caching systems such as Redis and Memcached.
Deep experience with containerization and orchestration technologies, including Docker, Docker Compose, and Kubernetes.
Advanced experience with AWS/Azure/GCP, including infrastructure automation, networking, security, and managed services.
Practical experience with managed CI/CD platforms (CircleCI, AWS CodeBuild/CodePipeline) and pipeline optimization.
Strong Git practices and experience conducting code reviews using GitHub workflows.
Experience working within agile development and DevOps processes.
Comfortable writing technical documentation, runbooks, and architectural notes.
Ability to manage and prioritize multiple operational and development tasks in parallel.

Edgecom Energy is committed to creating a diverse, equitable, and inclusive workplace. We believe that a range of perspectives and backgrounds drives innovation, strengthens our team, and enhances the quality of service we provide to our customers. We are dedicated to building a culture where all employees feel valued, supported, and empowered to contribute fully to our mission.
