Payload System Software Integration Engineer Fastwater Staffing

On‑site in Montreal preferred; remote or hybrid possible for the right candidate.

Open to US and Europe based candidates.

As part of the Software Integration Team, you will serve as the technical focal point for software integration planning and execution, overseeing contributions from various development teams (digital processing, embedded control, test automation, and ground segment). You will define the integration strategy, verify interfaces, lead validation activities, and review documentation and development plans to ensure alignment with system‑level requirements.

• Define and maintain the software integration strategy and schedule across multiple teams and subsystems.
• Ensure the compatibility of software interfaces between digital payload units, system controllers, and test systems.
• Oversee the integration and test campaigns of software components in lab environments and, later, in system‑level payload testing.
• Drive the verification and validation (V&V) process for integrated software, ensuring traceability to system requirements.
• Coordinate closely with systems engineering to ensure software behavior aligns with payload‑level functional and performance expectations.
• Review software development plans, ICDs, interface documentation, test reports, and release notes to confirm completeness and compliance.
• Identify integration risks early and support troubleshooting, debugging, and resolution of system‑level software issues.
• Foster collaboration across software, hardware, and systems teams to ensure robust and consistent integration practices.

• Bachelor’s degree in Software Engineering, Computer Science, Electrical Engineering, or related field.
• 5+ years of experience in software development and integration, preferably in the aerospace or telecommunications domain.
• Strong experience leading software integration activities in complex, distributed systems.
• Good understanding of digital telecommunications payloads, especially architectures involving Software Defined Radio (SDR) and digital beamforming.
• Familiarity with embedded software, real‑time operating systems (RTOS), FPGA interfaces, and communication protocols.
• Hands‑on knowledge of test automation, CI/CD practices, and tools such as Git Lab, Jenkins, Python, MATLAB, and Docker.
• Ability to coordinate across disciplines and manage technical risks associated with software integration.
• Must be eligible to work in Canada and capable of obtaining necessary security clearance.

• Previous experience in Space and/or Constellation Operations.
• Knowledge of requirements management tools such as DOORS, Windchill, or Jama.
• Demonstrated capability to efficiently work autonomously and with little to no supervision.
• Strong written and verbal communication skills in English; knowledge of French considered favorably.
