Position Overview:

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.

Responsibilities:

• Lead and mentor engineering development teams across the full Software Development Life Cycle (SDLC) to ensure program and technical success
• Drive Continuous Delivery and DevOps Adoption: Lead and mentor engineering teams across the full Software Development Life Cycle (SDLC), emphasizing modern practices like continuous integration, continuous delivery (CI/CD), infrastructure as code, and automated testing to ensure rapid and reliable program and technical success
• Define Cloud-Native/Distributed System Architecture: Apply deep technical expertise to define technical objectives, establish resilient system architecture patterns (e.g., microservices, event-driven), analyze complex engineering challenges, and drive effective, scalable solutions for distributed systems
• Govern Engineering Quality and Resilience: Evaluate the quality, efficacy, and observability of engineering deliverables, including software design, development practices, automated deployment pipelines, and operational monitoring. Ensure adherence to high standards for performance, scalability, and system resilience
• Proactive Operational Risk Communication: Proactively communicate engineering status, architectural risks (including technical debt), and operational issues related to system performance, availability, latency, and security (DevSecOps) to program leadership and the customer in real-time
• Facilitate Architectural Alignment with Customers: Conduct technical exchange meetings (TEMs) with government customers and external stakeholders to present architectural roadmaps, secure design approvals, and ensure continuous technical alignment with evolving mission needs
• Champion Innovation and Technology Strategy: Continuously evaluate, prototype, and recommend emerging technologies (e.g., AI/ML integration, new programming languages, cloud services) to enhance the performance, security, and future capabilities of mission‑critical software systems

Required Qualifications:

• Bachelor’s degree in computer science or a related technical field
• 10+ years of professional software development experience
• Demonstrated experience as a Chief Architect, Associate Chief Architect, or equivalent technical leadership role, guiding teams through the full software development lifecycle and successfully deploying capabilities into classified government operational environments
• Strong cross‑functional communication skills and proven ability to collaborate effectively within small, fast‑paced teams, managing multiple tasks to meet program milestones and deadlines
• Proven track record of leading Agile software engineering initiatives across all phases, including design, development, configuration, integration, testing, and delivery to end‑users
• Experience in large‑scale system design and deployments on cloud platforms (e.g., AWS, Azure), with a deep understanding of architectural principles for scalability
• Familiarity with leveraging cloud services for Kubernetes deployments and management, virtual machine management, object storage, and serverless functions
• Ability to translate in‑depth system engineering analysis into actionable software development concepts and implementations
• Experience in code review processes, ensuring technical soundness, adherence to coding standards, and adequate testing (including unit and integration tests)
• Demonstrated experience working on projects with geographically distributed teams
• Excellent interpersonal skills and experience engaging effectively with virtual teams
• Active TS/SCI Security Clearance with ability to obtain CI Poly

Preferred Qualifications:

• Strong business acumen with a proven ability to align technical solutions with business objectives
• Experience developing software on cloud platforms such as AWS or Azure, with a solid understanding of cloud‑native architectures and design principles
• Familiarity with cloud services for container orchestration (e.g., Kubernetes), virtual machine management, object storage, and serverless computing
• Hands‑on experience in software application deployment, virtualization technologies, and containerization (e.g., Docker)
• Experience in one or more of the following areas:
• Satellite communication planning for individual satellites and constellations
• SIGINT (Signals Intelligence) and GEOINT (Geospatial Intelligence) mission planning operations
• Satellite command and control (C2) systems
• Satellite tasking for GEOINT and SIGINT collection
