  • Work independently on ambiguous problems, drive designs to decisions, and mentor other engineers through code reviews, pairing, and technical talks. 

  • Continuously identify and reduce technical debt that increases risk or developer friction. 

  • Collaborate with your Engineering Manager and tech lead to provide feedback on product roadmaps and backlog priorities. 

  • Coordinate with Product Engineering to design solutions that automate security processes across the SDLC. 

  • Suggest secure defaults and advise on clean coding practices, pipeline test coverage, and observability/alerting. 

  • Participate in standups, desk checks, tech huddles, and story grooming meetings to provide guidance where it moves the work forward. 

  • Record decisions, context, and outcomes related to design choices, and prepare Architecture Decision Records (ADRs). 

 

 

You Have: 

  • Bachelor’s degree in Engineering, Computer Science or Information Technology, or equivalent experience. 

  • 3 years of experience in software engineering, architecture, administration, observability in a large and distributed environment working across multiple teams. 

  • Knowledge of cloud native event-driven microservices-based architectures, including operational concerns such as performance, resiliency, observability, monitoring, service discovery, and routing. 

  • 3 years as a full stack engineer building and operating services in production, including modern web frontends with React or a similar framework. 

  • 3 years coding in higher-level languages such as Python or Java in a multi-team codebase. 

  • Experience implementing DevSecOps solutions that integrate smoothly into teams’ development lifecycles, with measurable improvement to developer experience. 

  • Experience deploying organization-wide secrets as a service and integrating with pipelines and runtime applications. 

  • Working knowledge of containers and Kubernetes, APIs, and web services, including building services with FastAPI or similar frameworks. 

  • Cloud experience with AWS, GCP, or Azure via UI, API, and CLI or automation 

  • Experience implementing infrastructure as code, such as Terraform and automation via API or CLI.
