Position: Mid-Level Software Integration & Test Engineer - Wireless SDR & Mesh Systems
Employment Type: Full-Time
Location: Hybrid (San Diego, CA)
Compensation: TBD
Clearance Level: Ability to obtain a Security Clearance required; U.S. Citizenship required
POSITION SUMMARYTRABUS has an opportunity for a Mid-Level Software Integration & Test Engineer to drive end-to-end software integration, automated regression testing, and final system validation for next-generation Software-Defined Radio (SDR) wireless mesh networking systems. In this role, you will design rigorous test cases, build automated test suites for embedded radio controls and REST APIs, and validate complex mesh networks from early software integration through final release verification.
RESPONSIBILITIES- Design, execute, and maintain detailed test plans and test procedures covering functional, performance, security, and edge-case scenarios for embedded software, REST APIs, and wireless mesh networks.
- Build, expand, and maintain scalable automated test frameworks using Python, PyTest, Robot Framework, or shell scripting integrated into CI/CD pipelines to ensure continuous software stability.
- Collaborate with software, RF, and hardware engineers to integrate embedded control software, low-level SDR firmware, RESTful microservices, and database layers into unified deployment candidates.
- Set up and conduct lab-based RF channel simulation, network impairment testing, hardware-in-the-loop (HITL) testbeds, and field testing to evaluate dynamic topology discovery and key performance metrics, including throughput, latency, and packet loss.
- Identify, reproduce, document, and track software defect reports using issue tracking systems such as Jira.
- Validate system readiness, generate verification reports, and approve software builds for final production delivery.
REQUIRED QUALIFICATIONS- 3-5 years of dedicated software testing and system integration experience.
- Strong proficiency in Python for building automated test suites, interacting with REST APIs, and parsing log file streams.
- Solid understanding of TCP/IP, UDP, socket communications, and experience using packet analyzers such as Wireshark to inspect traffic flow and diagnose network issues.
- Experience validating software on embedded Linux platforms, microcontrollers, or Software-Defined Radio (SDR) hardware setups.
- Hands-on experience testing REST APIs and microservices using tools such as Postman, PyTest, or custom script suites.
- U.S. Citizenship is required due to defense/government compliance requirements.
- Ability to obtain a Security Clearance is required.
DESIRED QUALIFICATIONS- Experience with CI/CD tools such as Jenkins, GitLab CI, or GitHub Actions and Docker containerization.
- Exposure to RF instrumentation, including spectrum analyzers, signal generators, or channel simulators, or SDR frameworks such as GNU Radio.
- Familiarity with dynamic mesh routing protocols such as OLSR or BATMAN-adv, or hardware-in-the-loop (HITL) environments.
EDUCATIONBachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
