Experience applying Domain‑Driven Design (DDD) principles and event‑driven patterns – designing maintainable services with clear bounded contexts, secure integrations, and reliable communication across cloud‑native applications.
Work in partnership with the Technical Product Owner – defining outcomes, priorities, and scope while maintaining architectural integrity and long‑term technical sustainability.
Lead the design and implementation of solutions within the squad, ensuring alignment with established Mission architecture.
Champion data integrity, performance, and operational resilience – ensuring all squad‑owned components are designed and implemented in alignment with Mission‑level architectural patterns.
Collaborate closely with the Agile Delivery Lead and cross‑functional partners – aligning technical direction, refining scope, and managing dependencies that impact squad delivery.
Own the delivery of key product features – ensuring they meet functional requirements as well as performance, security, and availability standards.
Ensure the quality of code produced within the squad – upholding engineering best practices, coding standards, and platform‑aligned patterns.
Lead and contribute to code reviews – providing constructive, actionable feedback to elevate engineering quality and develop team capability.
Use engineering metrics and feedback loops to monitor squad performance – identifying improvement opportunities and supporting the evolution of a high‑performing engineering squad.
Mentor and guide engineers within the squad – supporting technical growth, skill development, and fostering a culture of continuous learning and improvement.
Stay informed on relevant industry trends and emerging technologies – applying insights to strengthen engineering practices and enhance the squad’s technical capability.
Requirements of the Role
What you’ll bring to the team
Ability to execute squad‑level technical direction and architectural decisions – linking these to measurable outcomes including feature performance, system reliability, and customer impact.
