Pre-Screening Interview Questions to Ask a Biorobotics Engineer

Last updated on

A device that interacts with a body is a medical device with all that follows. These questions test engineering depth alongside safety and regulation.

TL;DR, what to screen for

The best pre-screening questions for a biorobotics engineer test four things: systems they built that were tested with people or tissue, whether signal processing and control are solid, whether safety and regulatory requirements shaped the design, and whether they work with clinicians properly. Ask how the device fails safely.

Why pre-screen biorobotics engineers before the technical panel

Once a robot touches a person, the engineering changes. Force limits become safety requirements, a control loop failure has physical consequences, and the whole thing needs a risk file and a regulatory route. Engineers worth hiring design the failure behaviour before the capability. A short screen asks how the device fails safely, which separates biomedical engineering from robotics with a medical application.

What actually matters when screening Biorobotics Engineer candidates

  1. 01

    Technical depth

    Check depth in bio-inspired mechanism design: compliant actuators, series elastic joints, EMG or IMU signal conditioning, ROS 2 control loops, musculoskeletal modelling in OpenSim or MuJoCo.

  2. 02

    Work that shipped

    Probe hardware they actually built: exoskeleton prototypes, prosthetic hands, swimming or legged robots, cadaver or human subject rigs, and whether devices reached trials or production.

  3. 03

    Diagnosis under uncertainty

    Test how they debug on the bench: unexpected actuator drift, tendon fatigue, noisy surface EMG, gait phase misdetection, and how they isolated mechanical versus firmware causes.

  4. 04

    Working across the org

    Assess collaboration with physiotherapists, clinicians, IRB or ethics boards, and machinists; look for evidence they translated clinical requirements into mechanical and control specifications.

12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.

Systems they built

3 questions
  1. 01Do you have experience designing robotic systems for biological or medical use?

    Listen for

    Systems built and tested with people or tissue, with the application and their own scope described.

    General robotics experience presented as biorobotics, or nothing tested outside the laboratory bench.

  2. 02Can you describe your experience with biomedical systems or device development?

    Listen for

    Development within a design control process, with requirements traced through to verification.

    Development described informally, or requirements never written down before building.

  3. 03What projects have you worked on involving bio-sensing and interactive interfaces?

    Listen for

    Sensing from a body handled with noise and movement artefact addressed as core problems.

    Biological signals treated as clean inputs, or artefact rejection not part of the design.

Control is solid

3 questions
  1. 04What training do you have in signal processing, control systems or neuroscience?

    Listen for

    Genuine grounding in at least one, with the ability to work alongside specialists in the others.

    Breadth claimed without depth anywhere, or control theory limited to tuning parameters.

  2. 05Do you have experience with robot programming and control?

    Listen for

    Control loops implemented with stability and timing understood, including behaviour under disturbance.

    Control implemented by trial on hardware, or stability never analysed before testing on a person.

  3. 06Do you have experience with computational modelling or simulation?

    Listen for

    Models used to predict interaction forces, with results validated against physical measurement.

    Simulation used as evidence of safety, or models never compared with measured behaviour.

Safety shaped design

3 questions
  1. 07How have you ensured safety in previous biorobotics projects?

    Listen for

    Force and speed limits enforced in hardware where possible, with defined behaviour on any fault.

    Safety implemented in software alone, or no defined state when a sensor or controller fails.

  2. 08Are you familiar with the regulatory standards for designing medical devices?

    Listen for

    Device classification and applicable standards known, with risk management applied during design.

    Regulation treated as a later stage, or risk analysis produced after the design was frozen.

  3. 09Can you discuss your approach to quality assurance and testing?

    Listen for

    Verification against written requirements with results documented, including failures and their resolution.

    Testing described informally, or failed tests resolved without a record of the change.

Works with clinicians

3 questions
  1. 10Have you collaborated with healthcare professionals on device development?

    Listen for

    Clinicians involved from requirements onwards, with a design change that came from watching use.

    Clinical input sought at validation only, or usability problems found during a trial.

  2. 11Do you have experience debugging both hardware and software issues in these systems?

    Listen for

    Faults isolated methodically across sensing, control and mechanics rather than by substitution.

    Debugging by replacing components, or hardware and software causes never separated.

  3. 12What methods have you used to validate robot prototypes?

    Listen for

    Bench testing followed by controlled testing with users, with acceptance criteria agreed beforehand.

    Validation by demonstration, or criteria decided after the results were known.

How to score responses

Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.

  1. Technical depth

    35%

    5Explains actuator bandwidth, impedance control gains and sensor fusion choices with equations and measured data, not just tool names.

  2. Work that shipped

    30%

    5x,, ed with pilot unitsationsype and:built .es and,uUOM built

  3. Diagnosis under uncertainty

    20%

    5Walks through a specific failure, the instrumentation used to localise it, and the redesign that measurably fixed it.

  4. Working across the org

    15%

    5Cites named clinical or biology collaborators and shows how their feedback changed a joint range, strap design or safety limit.

Once a robot touches a person, force limits become safety requirements. A one-way video screen asks how it fails safely.

Screening FAQ

Process basics

How long should a pre-screening round for this role take?

Fifteen minutes across eight to ten questions, answered async. Enough to establish systems they built, test their control and signals depth, and check safety and regulatory experience.

What mix of skills should I expect?

Mechanical, control and signal processing plus enough biology to work with clinicians. Few candidates are strong across all of it, so decide which side your team is missing.

Evaluating answers

What is the strongest signal when screening this role?

How the device fails safely. Engineers who have built for human interaction describe force limits and defined failure states. Anyone who answers about capability has not designed for a patient.

How do I judge their regulatory grounding?

Ask what device class their work fell into. Real answers name the classification and the evidence it required. Anyone who has not thought about it will discover the requirements late and expensively.
