QA Engineer (Firmware & Embedded Systems)

We are looking for a QA Engineer (Firmware & Embedded Systems) to join Ohme on a fixed-term contract, with the potential to move into a permanent position.

This role will play a key part in the delivery of Ohme's next-generation EV charger. You will help ensure the quality, reliability and performance of our embedded systems as we work towards an initial product release, followed by rapid feature iterations and enhancements. Working closely with firmware engineers, software engineers and QA colleagues, you will take ownership of testing activities that help bring high-quality products to market at pace.

• →Validate firmware and embedded systems: Design, execute and maintain testing across firmware, hardware and software integrations, ensuring products perform reliably in real-world conditions.
• →Translate requirements into quality outcomes: Review technical specifications and convert them into structured, executable test plans, test cases and acceptance criteria that provide comprehensive coverage.
• →Strengthen product documentation: Refine, challenge and create specifications where requirements are unclear, incomplete or outdated, working closely with engineering teams to establish a shared understanding.
• →Build and improve test frameworks: Leverage existing tooling or develop new test infrastructure to support firmware validation, regression testing and repeatable quality assurance processes.
• →Improve legacy coverage: Analyse existing firmware projects, identify quality gaps and areas of technical risk, and document clear testing requirements to support future development.
• →Own test assets: Develop, maintain and evolve test suites that provide meaningful coverage for Ohme's products, customer journeys and operational requirements.
• →Collaborate across engineering: Partner with QA engineers, firmware engineers and software engineers to identify high-value testing scenarios, prioritise risks and support successful product releases.

• Quality-driven: You care deeply about product reliability and take a systematic approach to identifying issues before they reach customers.
• Detail-oriented: You enjoy understanding how systems work beneath the surface and can spot gaps in requirements, specifications and test coverage.
• Pragmatic: You can balance thorough testing with delivery timelines, focusing effort where it will have the greatest impact on product quality.
• Collaborative: You build effective relationships across engineering teams and communicate findings, risks and recommendations clearly.
• Curious: You enjoy investigating complex technical problems and are comfortable working across hardware, firmware and software domains.
• Self-motivated: You take ownership of your work, proactively identify improvements and drive solutions with minimal supervision.

• Firmware and embedded systems testing: Proven experience testing firmware, embedded software or connected hardware products within a commercial product development environment.
• Test strategy and planning: Strong ability to interpret technical requirements and translate them into structured test plans, test cases and quality documentation.
• Test framework development: Experience creating test specifications, test frameworks or validation tools that improve testing efficiency and coverage.
• Legacy system analysis: Comfortable reviewing existing firmware implementations, identifying quality risks and producing clear, actionable documentation and recommendations.
• Testing methodologies: Strong understanding of functional, regression and exploratory testing approaches, with the ability to apply the right techniques to complex systems.
• Test design expertise: Demonstrable experience designing comprehensive test scenarios that validate both expected behaviour and edge cases.
• Test management tools: Experience using platforms such as TestRail, PractiTest, Xray or similar tools to manage test execution and reporting.
• Defect management: Strong proficiency with Jira, including defect triage, prioritisation and tracking throughout the development lifecycle.
• Agile delivery: Experience working within Agile and Scrum teams, contributing to iterative development and release processes.
• Communication and stakeholder management: Excellent written and verbal communication skills, with the ability to explain technical risks, defects and recommendations to both technical and non-technical audiences.

• Cloud platform exposure: Experience working with AWS services such as DynamoDB, CodePipeline and CodeBuild, or equivalent cloud-native platforms.
• AI-assisted testing: Experience with, or enthusiasm for, AI-driven testing tools and approaches that improve test quality, coverage or efficiency.
• Automation and scripting: Familiarity with Python for automation, tooling or firmware validation frameworks.
• Interest in clean technology: A genuine interest in electric vehicles, energy technology or the transition to a more sustainable future.
