This senior role is for a Software Architect/Principal Software Engineer, and requires technical leadership, system design, and implementation oversight of complex government system architectures for national critical systems. You will serve as the key decision-maker in defining the "how" a system will be implemented to meet its software requirements, coordinating efforts between ARKA and sub-contractors. The responsibility of this dynamic role is expected to evolve over the course of the program and includes fostering customer intimacy to ensure a full understanding of the customer's needs, and then successfully leading the engineering team to realize that critical vision.

ARKA is seeking an accomplished Software Architect/Principal Software Engineer who is deeply customer mission-focused and passionate about providing strategic technical leadership in the software architecture and design of complex government systems, requiring proven experience leading programs involving 30+ developers in a distributed environment. This principal technical authority will be responsible for creating robust system designs derived from comprehensive requirements analysis, developing and evolving system architectures for enterprise-level solutions, establishing and maintaining rigorous interface definition standards and APIs, and leading advanced software design tasks to ensure optimal performance and maintainability.

Beyond direct design, the architect is expected to drive technical consensus through trade studies, proactively identify and mitigate technical risks, act as the primary technical interface to leadership, government customers, and sub-contractor CA/CE’s, and actively participate in the mentorship and growth of the distributed engineering team, ultimately joining our team to help shape the development and delivery of custom solutions and providing significant opportunities for personal skill development at ARKA.

We offer generous relocation benefits for eligible candidates.

In support of work/life balance, many positions are available for a flexible schedule within the pay period. Ask us about the opportunity for flex scheduling if that’s of interest to you.
