Lead Sensor Validation Engineer

Safety Bolt; Stockholms kommun; On-site; SEK 900,000 - 1,300,000; Full time

Job summary

Safety Bolt in Sweden is seeking a highly skilled sensor characterization engineer to define and execute our entire validation program for the new retrofittable sensors.

This role focuses on designing experiments, building the methodology, and determining what the sensor can predict under various conditions, collaborating with firmware and mechanical engineers to translate findings into system specifications.

Qualifications

• Solid foundation in analog electronics and measurement systems.
• Ability to design, execute, and evaluate systematic test programs.
• Hands-on with measurement instrumentation (generators, analyzers, scopes).
• Open-ended experimental work with inventive methodologies.
• Cross-disciplinary thinking across electronics, signal processing, and algorithms.
• High ownership to define the test agenda.

Responsibilities

• Design and execute a systematic test and validation program for the Safety Bolt sensor, from individual component characterization to full system behavior under real-world installation conditions
• Define the sensor operating envelope: boundary conditions, measurement uncertainty, and statistical confidence requirements
• Develop test fixtures, measurement protocols, and custom test setups for ESR and inductance characterization
• Work with unknown-variable scenarios: what can we predict with a known bolt type but unknown environmental context? Design the experiments that answer this
• Define production test procedures and give input to calibration routines, so that quality and consistency can be ensured at scale
• Collaborate with FW and ME to translate test results into requirements and guidelines
• Gradually take increasing ownership of the analog front-end design as the role and team mature
