Span builds smart electrical panels and grid-edge technology that let homeowners and utilities manage distributed energy loads more efficiently.
OUR MISSION SPAN IS ENABLING ELECTRIFICATION FOR ALL ⚡ WE ARE A MISSION-DRIVEN COMPANY DESIGNING, BUILDING, AND DEPLOYING PRODUCTS THAT ELECTRIFY THE BUILT ENVIRONMENT, REDUCE CARBON EMISSIONS, AND SLOW THE EFFECTS OF CLIMATE CHANGE. - Decarbonization is the process to reduce or remove greenhouse gas emissions, especially carbon dioxide, from entering our atmosphere. - Electrification is the process of replacing fossil fuel appliances that run on gas or oil with all-electric upgrades for a cleaner way to power our lives. AT SPAN, WE BELIEVE IN: - Enabling homes and vehicles powered by clean energy - Making electrification upgrades possible - Building more resilient homes with reliable backup - Designing a flexible and distributed electrical grid THE ROLE TEST ARCHITECT (ENERGY SYSTEMS & GRID INTEGRATION) ROLE SUMMARY The Test Architect is a senior individual contributor who defines and owns the end-to-end validation strategy for SPAN's intelligent energy products — spanning hardware, firmware, cloud, and mobile. This role requires deep expertise in power/energy systems testing, HIL/HITL architecture, CI/CD integration, and cross-functional collaboration across India and US teams. The hire will directly raise release confidence, reduce field defects, and scale SPAN's global quality infrastructure. STEP 1. JOB DESCRIPTION As a Test Architect at SPAN, you will define and drive the end-to-end test strategy and architecture for SPAN's intelligent energy systems — including SPAN Panels, SPAN Drive, battery integrations, EV charging, and grid interactions. You will ensure system reliability, safety, and scalability across hardware, firmware, cloud, and mobile applications. KEY RESPONSIBILITIES - Define end-to-end validation strategy across SPAN Panel (Gen2/Gen3), SPAN Drive, battery systems (e.g., Powerwall, Franklin), and grid/load interactions. - Build system-level test architecture covering App ↔ Cloud ↔ Hardware ↔ Grid; mix manual, automation, HIL/SIL. - Apply risk-based testing for safety-critical power systems; ensure coverage for corner cases and failure modes. - Lead validation of energy flows, outages, failover, backup scenarios, interoperability with inverters, batteries, and EVSEs. - Partner closely with teams on third-party integrations to validate end-to-end behaviours. - Architect scalable HIL/HIL environments with simulators and emulators. - Standardize lab procedures and fixtures; ensure India and US labs are aligned and interchangeable. - Integrate suites into CI/CD (Buildkite, Jenkins, GitHub Actions); enforce quality gates and build health signals. - Define and track coverage (feature/system/integration), defect leakage/escape rate, pass rate, MTTR, and MTTD. - Standardize dashboards in JIRA, TestRail; ensure traceability requirements → test cases → defects. - Collaborate with Product, Firmware, Software, and DevOps to align on release risk and validation scope. REQUIRED SKILLS & EXPERIENCE Core Expertise - Test Architecture for system-level products across hardware, firmware, and cloud/mobile. - Automation frameworks (Python, JS, Robot/System frameworks), design patterns, reliability engineering mindset. - CI/CD and release pipelines; artifact versioning; environment orchestration; test data management. Domain Knowledge (Critical for SPAN) - Power/energy systems, EV, renewables; grid behavior (voltage, frequency, phase, outages). - Battery systems, inverters, EVSE; protocols CAN, Modbus, MQTT, REST APIs. - Hands-on with oscilloscope, power analyzers, grid simulators, and electrical safety practices. Tools & Technologies - CI/CD: Buildkite, Jenkins, GitHub Actions; OTA: Mender; Test tools: TestRail, JIRA, Jama; Embedded/Linux (Yocto). Nice to Have - UL/IEC compliance exposure; grid codes and safety standards; multi-region power systems experience. KEY TRAITS & IMPACT - Analytical, system-level thinking; superb debugging; clear communication and stakeholder management. - Ownership and bias for action; collaborative across US and India teams. - Impact: higher release confidence, scalable global testing, fewer field defects, faster time-to-market.
