Senior Backend Software Engineer, dot on

Backend Engineers play a multi-disciplined backend role, in shaping and building the backend for various public API, user-facing and background features, through to site reliability engineering (SRE) and cloud engineering. They work together with other people in the Product team to solve common goals and to help solve issues in production.

Backend Engineers responsibilities:

• Build and improve the backend for various public API, user-facing and background features, with everything from database models, GraphQL/REST APIs, background tasks/automations, integrating with third-party products, to continuous integration / deployment (CI/CD); in a secure, well-tested and performant way that meets our high internal standards for quality, style, maintainability, testing, security and best practices. Maintain and advocate for these standards through code review.

• Monitor services, databases and infrastructure health to help ensure reliability, availability, and scalability of the Dot On business critical product; identifying and resolving issues, and improving system design and reliability. Improve automations, analytics, observability, monitoring and alerting for our services, databases and infrastructure so we can better prevent and respond to operational incidents.

• Respond to and resolve urgent operational incidents through on-call rotations (weekdays and weekends, including nights), to help ensure the availability (SLO/SLA/etc) goals of Dot On’s business critical product are met - including taking ownership, from the offset through to root cause analysis, resolution, communications with users, and retrospectives. We are a small, talented team and share this responsibility as a team. Our product is strategically built and monitored to help prevent and mitigate operational incidents.

• Design, provision, manage, automate, and improve performance and security of cloud resources, databases and infrastructure using infrastructure as code (IaC), ensuring high availability (HA), reliability, resiliency, scalability and cost efficiency of the Dot On business critical product; whilst meeting our high internal standards for quality, style, maintainability, security and best practices. Manage database backup, and data integrity strategies.

• Take ownership of projects; shaping the direction, making decisions, talking to users when needed, and communicating progress.

• Improve performance by profiling and tracing.

• Fix prioritised issues from the issue tracker in order of severity/priority.

• Continuously learn and expand both (a) domain knowledge relevant to the Dot On product (supply chain operations, etc), and (b) technological knowledge relevant to the Dot On product technologies.

• Redefine best-in-class (retail, etc) supply chain operations processes so that we can build an opinionated product.
