automated testing, vulnerability scanning (e.g., SonarQube, Fortify, OWASP)

, and

infrastructure as code (IaC)

into the delivery pipeline. Promote cloud-native principles including

containerization, scalability, fault tolerance, and observability

. Collaborate with DevOps engineers to optimize deployment workflows and incident response processes.
#

Agile, DevOps & Delivery Excellence

Drive architecture and delivery within an

Agile Scrum environment

, ensuring iterative and incremental design aligned with sprint goals. Embed

DevSecOps culture

and continuous improvement mindset across engineering teams.

#

Solutioning Support

Partner with bid and delivery teams to develop architecture proposals, estimations, and technical documentation for pre-engagement activities. Participate in client workshops to validate assumptions and align solutions with mission needs.

What You Bring

8+ years of experience

in software engineering and architecture, preferably in large-scale or mission-critical systems. Strong hands-on expertise in

REST API design

,

microservices

, and

event-driven architectures

. Proven ability to design

CI/CD pipelines

for cloud-native applications, ideally on

AWS

(e.g., CodePipeline, ECS, CloudFormation, CloudWatch). Deep understanding of

Agile and DevOps practices

, with real-world experience in iterative design and continuous delivery. Practical exposure to

security hardening, performance optimization, and resilience engineering

. Strong communicator who can bridge technical and business perspectives effectively. Experience in

public sector or regulated domains

is an advantage.
