Position

Description:

Protingent Staffing has an exciting contract opportunity located in Long Beach, CA.

• Own the architecture and implementation of scalable automation frameworks (primarily using Python and/or Rust) to validate full‑stack vehicle software including FSW, ESW, and configuration artifacts across software‑in‑the‑loop (SITL), hardware‑in‑the‑loop (HITL), and integrated system environments, leveraging reusable libraries, automation services, and structured validation interfaces.
• Develop automated integration and end‑to‑end test suites that exercise real‑time control flows, telemetry, mission sequences, and failure scenarios in both SITL and HITL setups.
• Implement automated test cases and analyzers that benchmark performance, validate qualification metrics, and publish dashboards (e.g., Grafana) to improve traceability and data‑driven decision making.
• Drive continuous test execution through CI pipelines (BVT, integration, nightly, weekly) to deliver fast regression feedback and release confidence.
• Lead system‑level test execution during release cycles—prepare environments, execute scenarios, evaluate results, and maintain traceable artifacts.
• Validate subsystem integrations prior to full‑system execution, perform root‑cause analysis during anomalies, and coordinate with development teams for resolution.
• Present release readiness reviews by aggregating test results, metrics, quality gates, and risk assessments.
• Mentor engineers on automation architecture, instrumentation strategies, and scalable test‑design patterns.

• 5+ years of experience in software development or test engineering, including 2+ years architecting automated test frameworks for integrated systems combining hardware, firmware, and software.
• Proven ability to design and scale unit, integration, and system‑level automation frameworks, with strong software skills in Python, Rust, or C++ for tooling, validation pipelines, and simulation workflows.
• Excellent debugging skills, strong ownership, and attention to detail, with ability to operate in fast‑paced, cross‑functional environments.
• Familiarity with CI/CD workflows, containerization (Docker), telemetry/log aggregation, and automated test pipelines.
• Demonstrated ability to work effectively across software, hardware, and operations teams to align on delivery milestones and integration needs.

• Experience in aerospace, robotics, safety‑critical systems or embedded real‑time applications.
• Hands‑on experience validating embedded, real‑time, networking or hardware‑integrated systems, including controller, sensors/actuators, communication buses, and timing‑sensitive behaviors.
• Familiarity with Conda, Git Lab CI/CD, Grafana, version control practices, artifact repositories.
• Experience working with hardware‑in‑the‑loop (HITL), simulation environments, or large‑scale system integration.
• Strong analytical skills and experience supporting data reviews, root cause investigations, or release audits.

• Job Type: Contract
• Location:
  
  Long Beach, CA.
• Pay Rate Range: $60‑70/hr.
