Job Summary:

Teledyne FLIR is looking for a career Software Engineer to join our Surveillance team who has experience leading complex projects independently from inception to completion. This team, along with a sibling location in Victoria, BC, delivers military-grade software and hardware solutions for defense and border security applications. As customer demand continues to grow, we are seeking a strong software professional to help develop the next generation of mission-critical solutions.


This position focuses heavily on the Microsoft platform, with an emphasis on .NET server-side technologies and some desktop development. We are seeking an experienced software engineer who has intentionally chosen the technical individual contributor path and enjoys remaining deeply involved in software design, development, and problem solving. While this role provides significant technical leadership and ownership of complex initiatives, it is not a people-management or product-management role. The ideal candidate will have 10-15 years of experience shipping production software and will enjoy solving challenging technical problems while collaborating effectively with teammates and stakeholders. Experience with client-server and distributed architectures, front-end UI, middle-tier systems, and multithreaded applications is highly desirable.

Job Duties & Responsibilities:

  • Design, build, and maintain high-quality software for defense and border security applications
  • Collaborate with developers, QA, product managers, and project leads
  • Lead software initiatives while staying hands-on with coding
  • Solve challenging technical problems across server-side and desktop platforms
  • Develop and optimize client-server and distributed systems
  • Implement multi-threaded and asynchronous programming patterns
  • Work with internet protocols (HTTP, TCP, UDP, SSL) and video streaming
  • Communicate clearly with stakeholders and team members
  • Participate in testing and resolving software defects

Job Qualifications:

  • Bachelor’s degree in Computer Science or related field required, Master’s degree a plus
  • 10-15 years of software development experience on Windows and Linux platforms
  • Demonstrated ability to lead complex projects independently and collaborate effectively are required
  • Strong skills in .NET server-side development and object-oriented design
  • Experience with C#, .NET Core, REST, WPF, JSON, LINQ, and microservices
  • Familiarity with C , NoSQL, WebSockets, and video protocols a plus
  • Experience with agile or lean development practices a plus
  • Able and willing to travel approximately 10% for demos and installations (domestic and international)


Applicants must be either a U.S. citizen, U.S. national, legal permanent resident, asylee, refugee or must be eligible to apply for and obtain the appropriate export control license from the U.S. Departments of State or Commerce.
