Role Description

This is a remote volunteer position for a Senior Software Engineer in our Infrastructure, Technology & Engineering (ITE) Team. You are not just a builder, you are a technical coach, mentor, and owner of engineering outcomes.

Be the Dubs "Tech Anchor" – you take ownership of engineering projects, guide junior engineers, and ensure our systems are reliable, scalable, and mission-ready.

While Junior Engineers learn the stack and contribute to features, you lead the architecture, set the standards, and mentor the team. You don't just write code—you ensure the right code gets written, the right problems get solved, and the right practices get followed.

1. Technical Leadership & Ownership

Own end-to-end engineering projects from requirements through deployment and maintenance
Make technical decisions on architecture, tooling, and implementation approaches
Review code from Junior Engineers, providing constructive feedback and teaching moments

Design system integrations between the learning platform, social media, data lakehouse, and internal tools
Implement monitoring and alerting to ensure system health and uptime
Lead incident response when systems fail, conducting post-mortems and implementing fixes

4. Cloud Computing & Systems Infrastructure:

Break down complex projects into manageable tasks for junior engineers
Estimate effort and set realistic delivery timelines
Communicate technical decisions to non-technical stakeholders (OpEx, LearnOps leadership)
Document system architecture, decision records, and operational runbooks
Collaborate with the Operational Excellence (OpEx) Team – including Process Engineers
Work closely with the Delivery Enablement Team (Agile Coach) – to align engineering delivery with organizational workflows and continuous improvement practices.
