You'll join a multidisciplinary development team working on a national platform used in public safety, traffic enforcement and investigative work. As a senior back-end engineer, you will build and integrate back-end services that generate and manage "hits" from cameras in real time, helping frontline teams act faster and more accurately.
You work closely with other developers, architects, functional analysts, project managers and external partners, and you report to a DevOps Team Lead. The environment is technically complex, security-focused and mission-critical.
What you will do
* You will design, build and maintain robust back-end components and services in
PHP
and
TypeScript
, and connect them with other systems through
RESTful APIs
, messaging, and hybrid/on-prem infrastructure.
* You will read and understand functional analysis and turn it into clean, maintainable code, continuously refactoring to keep the codebase healthy.
* You will help prototype new components and proof-of-concepts, iterate quickly based on feedback, and integrate with external software whose codebase is not always internally available.
* You will work day to day with product owners, functional analysts, technical engineers, QA, and specialists in hardware, AI/ML and UX to deliver end-to-end solutions.
* You will participate in co-creation workshops with internal teams and external vendors to design integrations, APIs and real-time data pipelines.
* You will take part in peer code reviews, give and receive constructive feedback, and help raise the technical bar for the team.
* You will also contribute to modern
DevSecOps
practices: working with CI/CD pipelines across DEV/TST/ACC/OPS/TRG environments, supporting deployments and integration testing (while the overall pipeline ownership sits with the DevOps function).
