Premium Ad IT/Computer - Other IT/Computer Cape Town FULL TIME Job Summary Our client within the mining consulting industry is looking for a  Senior Backend Software Engineer to join their team in Cape Town, WC. Role Overview: We are looking for a senior backend engineer to join the team building WIRE, the platform our clients use to run their mining operations. Day to day, you will be writing Python—our backend is Flask and SQLAlchemy on PostgreSQL, with Celery handling the heavier processing behind it. We are also migrating parts of the platform onto Go, and this role will play a hands-on part in that migration rather than watching it happen from the sidelines. This is a senior, largely autonomous delivery role. You will take ambiguous or partially-formed requirements, shape them into a workable design, and see the work through to production. You will be trusted to make the call on smaller architectural decisions yourself and to bring options, not just problems, on the bigger ones. Alongside delivery, you will help raise the bar for the engineers around you through review, mentoring, and setting a good example in the codebase. Responsibilities: Technical Delivery * Own the design and delivery of backend features in Python and GoLang, using Flask and SQLAlchemy against PostgreSQL, from ambiguous requirements through to production. * Write database migrations and think through the impact on existing client data before they run, including rollback plans for anything non-trivial. * Design and maintain background processing using Celery, including diagnosing and resolving issues under load. * Write and tune SQL directly where the ORM is the wrong tool, particularly for large-volume operational data retrieval. * Design and maintain stable, versioned API endpoints, with an eye on backward compatibility for clients already depending on them. * Take a leading role in migrating existing services to Go, including making design decisions on how new services are structured. * Diagnose and resolve production issues, including under time pressure, and drive the fixes through to root cause rather than just the symptom.
