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

As a Software Engineer, you'll play a crucial role in ensuring the quality and reliability of our products through a combination of automated and manual testing methodologies. This is a high impact role that will work closely with SPAN’s internal Software, Device Software, Hardware Engineering, Systems, and QA teams.

Role & Responsibilities

As a Staff Software Engineer in Automation, you will be expected to:

• Co-design test automation infrastructure with Systems and Test Infrastructure. Automation provides the platform and drivers; partner teams write the tests.

• Diagnose automated test failures across firmware, hardware, and test infrastructure.

• Help manage and grow a fleet of 50+ hardware test rigs across offices.

• Monitor hardware and software infrastructure health.

You will take architectural ownership of one or more of the team's critical systems. Examples of where you might focus:

• Hardware-in-the-loop test execution: on-premise orchestration of test sequences on physical hardware, integrated into CI/CD for PR gating and release qualification.

• Test data pipeline: telemetry ingestion from rigs, structured storage in PostgreSQL, reporting dashboards for release readiness and reliability.

• Test execution framework: instrument driver library, sequence engine, and the gRPC services that tie rigs together.

The specific focus depends on your strengths and the team's needs at the time you join.

About You

Required Qualifications

• Demonstrable proficiency building reliable tools and services in Python.

• Able to read and reason about C++, Rust, TypeScript, or similar. Not your daily language, but enough to follow a bug across a boundary.

• Experience with hardware-adjacent software: software that controls, monitors, or ingests data from physical devices or instruments.

• Experience owning internal platform infrastructure where your users are other engineers and your systems are in the critical path.

• Comfortable standing up new tooling from scratch and retiring it when needs change.

• Experience operating CI/CD infrastructure, particularly pipelines that run on physical hardware.

Additionally, there are three primary focus areas, you should fit into one or more of these:

HITL-relevant:

• Understanding of hardware-in-the-loop testing, reliability testing, and certification testing methodologies.

• Experience managing fleets of physical test cells or lab infrastructure (Ansible, AWX, or similar).

• Experience with embedded systems or firmware testing (CAN bus, SWD debugging, firmware update flows).

Data pipeline-relevant:

• Experience with time-series data: ingestion, storage, and querying of telemetry.

• Experience with PostgreSQL, S3/AWS.

• Experience building reporting dashboards for engineering or leadership audiences.

Framework-relevant:

• Experience with gRPC or similar RPC frameworks.

• Experience with lab instrumentation control. Power analyzers, load simulators, signal generators, relay boards.

• Experience designing automated test rigs or test cells from requirements through physical buildout to software integration.

Bonus Qualifications

We would love to hire someone who has:

• Experience working in a startup environment.

• Experience working in the renewable energy industry.

• Experience with Ansible or similar configuration management for physical infrastructure.

• Experience with or preference for a rapid or continuous release cadence
