If you’re skilled across Go, JavaScript, and Python, adaptable across the full stack, and enjoy owning features end‑to‑end with a focus on quality, efficiency, and innovation, we’d love to have you on our team.

This is a full‑time, hybrid position based in Ashburn, VA, with minimal travel (0–10%).

Essential Functions

• Collaborate with Agile team members to design, develop, test, and implement secure, high-quality full stack solutions.
• Capture and review functional requirements; participate in architectural design and code reviews.
• Build and ship features end‑to‑end across our web applications — front‑end (React), backend services (Go and Node.js), and the data layer (MySQL and MongoDB).
• Develop and extend our Go automation agent that configures, tests, and validates devices, including real‑time data flows over MQTT.
• Contribute ideas and improvements to the team’s development practices and tooling, and share knowledge across the team.

Minimum Qualifications

• Technical Expertise: Strong programming fundamentals with proficiency across multiple languages — we work primarily in Go, JavaScript/Node.js, and Python — and the adaptability to pick up new frameworks, tools, and datastores as our stack evolves. Solid grasp of data structures, algorithms, and object‑oriented or functional design.
• Linux, Distributed Systems & Device Automation: Hands‑on experience developing, debugging, and optimizing Linux‑based distributed systems, including writing Go services that interact with hardware or networked devices to configure, test, and collect data from them.
• Full‑Stack Web & Cloud: Experience building RESTful web services, working with relational and/or document databases (we use MySQL and MongoDB), and building modern, responsive front‑ends (our primary UI is React), deployed to AWS cloud services (ECS, EKS, RDS, API Gateway).
• Testing: Experience building automated testing into the development process, including unit and integration tests for backend services and end‑to‑end tests for web applications (we use Ginkgo, Cypress, and Postman).
• 5+ years of relevant experience with a Bachelor’s degree in Computer Science or a similar field, or 3+ years with a Master’s degree, or equivalent experience.
• Ability to obtain a security clearance.

Preferred Qualifications

• Familiarity with monitoring/observability tools (Prometheus, Grafana, Datadog, AWS CloudWatch).
• Familiarity with CI/CD tooling (Docker, Terraform, CodePipeline).
• Experience with AWS GovCloud for building secure, compliant solutions in regulated environments (e.g. defense).
• Familiarity with AI/ML frameworks (e.g. TensorFlow, PyTorch) and AI‑assisted development tools.
• Strong problem‑solving, communication and collaboration abilities.
