Systems Test Engineer

OLG Recruitment are currently looking for a Systems Test Engineer for our client located in Stallingborough. This is a contract opportunity up to October.

As a Systems Test Engineer, you'll be embedded in the test engineering team, working alongside firmware, hardware, and compliance engineers. Your day-to-day work spans from functional bring-up and interface characterisation through to scripting automated test suites and expanding the HIL (Hardware-in-the-Loop) test system to accommodate new product variants.

Summary

You are an experienced test or embedded systems engineer comfortable working across hardware bring-up, software/firmware interface testing, and test automation. You're at home with a logic analyser in one hand and a Python script in the other : equally able to characterise a new PCB's wireless interface and write the automated test that will verify it on every future build.

You'll work alongside the myenergi test team to validate new product variants from first-board bring-up through to factory-readiness, and to build the automated test infrastructure that makes repeatable validation possible at scale.

Hardware Bring-up & Interface Validation

Validate new  PCB variants at board level — power-on sequencing, signal integrity, interface checks

Test and characterise all communication interfaces: Ethernet, Wi-Fi, BLE, 4G/LTE, and PLC (ISO 15118)

Diagnose and document hardware/firmware integration issues; work with firmware engineers to identify root causes

Support pre-compliance testing activities alongside the companies compliance team : EMC prescreening, electrical safety checks, grid connection interface validation (G98/G99 awareness)

HIL Testing & System Expansion

Execute existing HIL (Hardware-in-the-Loop) test suites for new product variants

Expand HIL system compatibility to cover new hardware configurations : add new test points, update stimulus/response scripts, validate coverage gaps

Work with the firmware and test teams to align HIL scenarios with real-world use cases

Test Automation & Scripting

Write new automated test scripts covering interface, functional, and regression test cases

Build or extend test applications and tooling that integrate with the existing CI/CD pipeline

Develop reporting infrastructure : clear, structured test reports that communicate pass/fail status, coverage, and defect details to engineering and product teams

Align test cases with Jira and ensure traceability from requirement through to test evidence

Factory Test Support

Support production engineering to configure and validate bed-of-nails test fixtures for new variants

Assist with EOL (end-of-line) test rig setup — ensuring factory test coverage matches product specification

Document factory test procedures and pass/fail criteria clearly

Embedded systems test experience : hands-on validation of electronic hardware/firmware products; comfortable with PCB bring-up, lab equipment, and debugging unfamiliar boards

Interface & protocol testing : proven experience testing at least two of: Ethernet, Wi-Fi, BLE, 4G/LTE, PLC or CAN : at a functional and diagnostic level (not just ping-and-pass)

Test automation scripting : Python or equivalent; experience writing structured automated test scripts that run in a CI/CD context

HIL or bench test systems : experience operating and extending hardware-in-the-loop or automated bench test environments

Test reporting : able to produce clear, structured test reports; experience with test management tools (Jira, Qase, or equivalent)

Communication : comfortable working in a multidisciplinary engineering environment; clear written and verbal reporting

On-site availability at Stallingborough for the duration of the contract

Desirable Skills & Experience

Knowledge of EV charging standards or residential energy systems (IEC 61851, OCPP, ISO 15118, G98/G99)

Experience with pre-compliance or EMC test activities

Familiarity with CI/CD systems (Jenkins, GitHub Actions)

Factory test or production test experience (bed-of-nails, ICT, EOL)

Electronics or Embedded Systems degree (or equivalent practical background)

AI-assisted testing : use of AI tools to accelerate test script generation, documentation, or defect analysis
