Your Position & How You Will Contribute:
Reporting to the Head of Network & Systems, the Senior Full Stack Developer owns the internal platform that connects our network to everything else. This is not a greenfield project — there is a real codebase, real integrations, and real dependencies that the business runs on every day. Your job is to make it better: cleaner, faster, more reliable, and easier for the team to build on. The platform touches nearly every part of the operation: customer communications, billing automation, NOC workflows, provisioning, field ops tooling, and reporting. You will be the most senior technical voice on a small, capable team, working directly alongside contractors and setting the standard for how the work is done.
Responsibilities & Key Duties:
-
Platform Ownership: Maintain, extend, and improve the internal Go codebase that integrates our network elements, enterprise systems, and operational workflows.
-
Integration Architecture: Own the API and database integration layer across a broad and evolving set of systems — including OSS/BSS platforms, network elements, and third-party commercial services.
-
Technical Standard-Setting: Set the bar for code quality, design patterns, and development practices on the team. Review contractor contributions and provide clear, actionable feedback.
-
Delivery: Ship features and improvements with the discipline to scope, estimate, and follow through.
-
Collaboration: Work closely with the Business Systems Analyst, the Visibility & OSS team, and other internal stakeholders to translate operational needs into working software.
What You Bring:
-
Technically Grounded: Able to wtite clean Go and knows why. Understands how distributed systems fail and builds things that are easier to debug when they do.
-
Integrations Experience: Has connected real systems to each other — APIs, databases, queues, webhooks. Comfortable designing integrations that hold up when the external system behaves unexpectedly.
-
Domain Curiosity: Telecom, ISP, or network operations experience is a strong asset. Genunie interest about how IP networks, provisioning systems, and billing automations intersect – and the initative to learn the domain.
-
Ownership Mentality: Not precious about the codebase inherited. Tales responsibility for making it better, cleaner, better documented, easier to build on without rewriting everything first. Leaves things in better shape than they were found.
-
Clear Communicator: Able to explain a technical restraint to someone who does not write code and a busiess requirement to someone who does. Keeps stakeholders informed without over-communicating.
Experience:
-
Strong Go development experience in a production environment. Comfort across the stack — API design, database integration, job scheduling, lightweight front-end where required.
-
Experience integrating with external APIs at scale: REST, GraphQL, webhooks, or similar.
-
Familiarity with Linux environments, containerization, and deployment basics.
-
Exposure to telecom or ISP systems is a significant asset: OSS/BSS platforms, provisioning systems (Kea DHCP, PON EMS), network element APIs, or billing automation.
-
Experience in a small team where you wore multiple hats and shipped without a lot of process overhead.
-
Contractor or vendor code review experience is an asset.
Education:
-
Degree or diploma in Computer Science, Software Engineering, or equivalent practical experience. Credentials are an asset, not a requirement.
