Job Description:
As a Lead QA Engineer at Fluence, you will play a crucial role in validating gigawatt-scale Battery Energy Storage Systems (BESS) and ensuring the high availability of our control software. Taking ownership of an established, high-performance automation ecosystem, you will focus on end-to-end validation of complex power systems, grid-forming integration, and advanced hardware-in-the-loop (HIL) testing.
Key Responsibilities:
Automation Ecosystem Management: Maintain, enhance, and scale our existing automated testing frameworks.
Performance Engineering: Utilize our high-performance Rust and Python test environments to identify and mitigate P99.9+ latency outliers, ensuring performance for critical controls operations.
Infrastructure & Simulation: Manage and expand containerized (Docker) simulation models and HMI performance testing environments to support agile development and stress-test system responsiveness.
Integrated HIL Testing: Execute and refine HIL API integration test suites, validating grid forming applications and integrated system performance.
Commissioning & Integration Support: Serve as a technical escalation point for live remote commissioning of production sites, troubleshooting real-time integration issues across Modbus (TCP/RTU), MQTT (Sparkplug B), or PostgreSQL.
Agile Leadership: Drive the adoption and enforcement of Scaled Agile Framework (SAFe) product strategy and agile methodologies across engineering teams, acting as strong advocate for process discipline in a dynamic environment.
Technical Leadership: Lead technical workshops, mentor junior QA and systems engineers, and maintain robust process documentation to propagate best practices across the engineering teams.
Quality Metrics: Drive continuous improvement in test coverage, reliability, and CI/CD pipeline efficiency.
Minimum Qualifications:
Education & Experience: M.S. degree in Electrical Engineering, Computer Science, or a related technical field
8+ years of experience in software quality assurance, test engineering, or a related field within the energy storage, power systems, or industrial controls industries.
Core Skills: Strong proficiency in Python (or similar object-oriented scripting language) for test automation and system simulation. Experience working within and contributing to Agile/Scrum methodologies.
Tools: Solid experience with CI/CD pipelines (e.g., Jenkins), GIT, and Linux/Bash.
Soft Skills: Excellent ability to write technical documentation, lead cross-functional workshops, and drive issue resolution.
Required Qualifications and Experience:
Agile Strategy: SAFe Certification (e.g., SAFe Agilist, SAFe Practitioner) or deep, proven experience implementing and scaling SAFe product strategies in complex hardware/software ecosystems.
Advanced Programming: Practical experience with **Rust**, particularly in the context of high-performance tooling or simulation.
Specialized Testing: Extensive background in Hardware-in-the-Loop (HIL) testing, API validation (REST/GraphQL), and HMI/SCADA performance validation.
Protocols: Deep expertise in networking and messaging protocols, specifically Modbus (TCP/RTU), OPC UA, and MQTT (Sparkplug B).
Power Systems: Familiarity with BESS control algorithms, Grid Forming Inverters, Primary Frequency Response, or power systems analysis tools (MATLAB/Simulink, Wireshark).
Infrastructure: Proficiency in Docker container creation, orchestration, and infrastructure troubleshooting.
Analysis Tools: Competency with MATLAB/Simulink and Wireshark for deep system troubleshooting.
