Top Software Engineer Jobs in CO

Own and evolve the Subscriptions and Payments backend: design APIs, integrate providers, improve reliability and scalability, lead architecture and code reviews, collaborate cross-functionally, and participate in on-call rotations.

Lead design and delivery of large, software-intensive distributed systems across cloud, AI-enabled, and mission environments. Define architectures, integration strategies, and validation approaches; drive technical tradeoffs, risk mitigation, operational readiness, and cross-team alignment while mentoring senior engineers and scaling systems engineering practices.

Develops satellite ground-system software for command and control, mission planning, and data analysis. Performs full software lifecycle activities, including requirements, architecture, design, coding, testing, integration, documentation, and support. Works on a cross-functional Agile team delivering reliable capabilities with CI/CD practices. The role is fully on-site five days per week and may involve travel between company campuses or other locations.

Develops and rapidly prototypes scientific algorithms for imagery, video, signals, detection, tracking, sensor fusion, artificial intelligence, and machine learning applications. Automates algorithms for batch and near-real-time processing, evaluates performance, documents research, and communicates findings to technical teams and customers. The role requires collaboration in an R&D environment, customer interaction, technical leadership for junior colleagues, and development using Python and MATLAB.

Design, develop, integrate, and certify a company-wide digital test procedure application. Participate in requirements, architecture, implementation, CI/CD, and Agile development. Collaborate cross-functionally, communicate status to management, train staff, improve processes, and support system-level testing and certification. On-site presence required three+ days per week.

Contribute to full-stack features for spacecraft mission control and distributed ground control systems. Build React/TypeScript frontends and Elixir backend services, write maintainable and testable code, collaborate with operators, designers, and engineering specialists, and participate in design and code reviews. The role involves smaller, well-defined tasks under senior guidance during a three-month temporary engagement with potential conversion.

Develop and test flight software for spacecraft computers, integrate GNC algorithms, maintain command telemetry databases, support command scripting, build subsystem simulators, and create device drivers and communications libraries. The role involves embedded RTOS development, hardware integration, mission testing, and collaboration with ground-control software teams. This is a three-month onsite temporary engagement in Denver or Long Beach, with potential conversion to regular employment.

Develop and maintain modern C++ spacecraft simulation software and multi-physics libraries. Model spacecraft dynamics, thermal systems, attitude control, propulsion, power, sensors, and actuators; implement numerical solvers and time-stepping algorithms; maintain Python and C++ APIs; and collaborate on mission planning, algorithm development, testing, code reviews, and sprint planning.

Develop and maintain full-stack enterprise applications for a Workforce Management System using Java, Spring Boot, React, and JavaScript. Design REST and SOAP services, implement microservices, write test-driven code, deploy through Jenkins and Docker, troubleshoot production issues, participate in architecture and API reviews, and collaborate in Agile Scrum/XP teams. Review code, maintain existing systems, and provide technical guidance to junior developers.

The Staff Forward Deployed Engineer at GitLab works with strategic accounts to adopt GitLab and GitLab Duo Agent Platform, guiding technical discovery and building reusable solutions for complex enterprise environments.

Build and ship production-grade agentic AI developer tools and a coding harness to modernize legacy systems. Design integrations across source control, CI/CD, security scanners, and cloud services. Partner with customers and product teams to iterate on AI-native workflows, ensure cybersecurity compliance, and scale agentic systems for defense missions.

Build and maintain FareHarbor.me, a managed WordPress site platform. Develop PHP and JavaScript features, craft themes/plugins and Gutenberg blocks, collaborate with design and product, review PRs, write docs, and improve accessibility, performance, and editor UX across thousands of client websites.

Build and scale Go backend services for agent quoting, configuration, and application submission. Partner with adjacent teams, resolve partner-specific edge cases, provide architectural leadership, write unit and integration tests, review code, and promote automation, CI/CD, and continuous improvement. The role expects daily use of AI coding tools and ownership of services across distributed systems and microservices environments.

Develop and maintain web-based applications across the full stack, including feature development, bug fixing, testing, debugging, documentation, and code reviews. Collaborate within an Agile team, research emerging technologies, troubleshoot operating systems, databases, applications, JavaScript, and networks, and contribute to process improvements. The role also includes mentoring teammates and delivering technical training.
