Top Hybrid Software Engineer Jobs in CO

Develop low-level, high-performance instrumentation within CICS and z/OS using HLASM. Design production features for mission-critical mainframe environments, diagnose complex system behavior through dumps and traces, analyze performance bottlenecks, and collaborate with an experienced engineering team. The role requires deep z/OS and CICS internals expertise, systems programming knowledge, and proficiency with JCL, SDSF, and USS.

Lead design, development, testing, and deployment of scalable Java/Spring Boot/Angular applications. Provide technical leadership and mentorship, define architectures, collaborate with product and cross-functional teams, review code, ensure quality/security/performance, troubleshoot production issues, and drive process and tool improvements.

Design and build backend services and APIs for identity resolution and platform integrations. Optimize event-driven pipelines processing billions of signals, deploy cloud-native services on AWS EKS and Kubernetes, and ensure reliability, observability, and scalability. Collaborate with engineering, product, and data teams to deliver identity solutions while mentoring junior engineers. The role requires expertise in backend or data engineering, distributed systems, streaming technologies, cloud deployment, data modeling, and high-throughput databases.

Develop and maintain a password-protected .AI KPI dashboard using Identity Digital Data Warehouse data and a mutually agreed web framework. The dashboard will provide near-real-time updates, executive-level views, drill-down functionality, and metrics covering registry growth, financial performance, technical infrastructure, and security. The contractor will collaborate with technical and business stakeholders, maintain an in-person presence in Anguilla, coordinate deliverables, and provide emergency support when required.

Lead design and implementation of modernized insurance underwriting and policy administration solutions. Drive cloud transformation, data-driven and secure architectures, improve risk selection and claims resolution, enhance customer experience through automation, mentor technical teams, manage client relationships, and oversee project lifecycle, budgets, and delivery quality.

Develops real-time simulations of space vehicles supporting flight software development, testing, ground-system development, integration, and operator training. Responsibilities span the full software lifecycle, including requirements, architecture, coding, testing, integration, and documentation. The role uses Agile workflows, GitLab, coding standards, and DevSecOps practices, with opportunities to work with containers, messaging protocols, high-performance data architectures, real-time operating systems, and hardware-in-the-loop simulations. The position is fully on-site and may require travel between facilities.

Lead architecture and technical direction for FreeWheel’s high-throughput Buyer Cloud Ad Serving platform. Design scalable, low-latency distributed backend services; optimize performance; drive reliability, observability, and cloud-native adoption; establish engineering standards; collaborate across Product, Infrastructure, SRE, and Data Engineering; and mentor engineers. The role requires operating production systems processing billions of auctions and potentially millions of requests per second, with occasional nights and weekends as needed.

Build, deploy, and operate scalable, fault-tolerant software products and tools used by millions of consumers. Design solutions, decompose complex requirements, leverage AWS and AI technologies, contribute to CI/CD, write tests, review code, and maintain observability, reliability, security, and cost efficiency. Lead technical initiatives, mentor engineers, and own solutions throughout the production lifecycle.

Own commercial navigation features end to end across mobile, backend, and web surfaces. Build reliable, customer-facing navigation experiences for commercial fleets despite poor connectivity, dynamic schedules, and changing routes. Define product priorities and success metrics, ship maintainable and tested code, improve observability, and collaborate with product, design, Maps, Telematics, and adjacent engineering teams. The role requires strong customer focus, technical depth, and the ability to make practical tradeoffs in ambiguous problem spaces.

Design, build, and operate scalable distributed systems for real-time restaurant payment and financial workflows. Responsibilities include architecting reliable services, protecting sensitive financial data, improving observability and production performance, debugging distributed systems, participating in on-call rotations, applying AI-assisted engineering tools, collaborating cross-functionally, and mentoring engineers.
