Full job description

TidalSense is a respiratory technology company with a mission to transform the diagnosis, monitoring and management of chronic respiratory conditions, such as asthma and COPD. The company has ambitions to enable a population-scale change in respiratory care through global deployment of its technologies in both developed and developing countries with poor access to healthcare. TidalSense has launched the first-of-its-kind AI-driven (software medical device) diagnostic test for COPD which uses the company’s unique, patented, sensor technology embedded in the N-Tidal Handset medical device.

We are seeking an Embedded Engineer to join our Hardware Team. We are at an exciting phase in our journey as we transition from a start-up to a scale-up. You will be joining a passionate, socially-motivated and multi-disciplinary team covering engineers, scientists, clinicians, designers, product and usability specialists. This is a unique opportunity for an ambitious individual to develop firmware solutions that will drive development and commercialisation of our medical devices, delivering life changing impacts in the real world. We are seeking someone who is comfortable working in a fast-paced, agile, diverse team environment, and who is committed to our mission to revolutionise respiratory medicine.

  • Able to write clean embedded C++ following modern software engineering practices
  • Able to design robust and secure systems and “edge-to-cloud" pipelines
  • Able to design and implement clean, maintainable code that prioritises simplicity and safety over overly-complex architectures
  • Familiar with benchtop testing equipment (eg oscilloscopes, logic analysers etc)
  • Possessing strong “soft-skills”, with the ability to:
    • Operate with high autonomy and ownership,
    • Find solutions to difficult problems,
    • Offer clear, strategic direction backed by concise reasoning,
    • Collaborate effectively across teams to deliver technical projects, and
    • Write clear, concise, high quality technical documentation
  • Good working knowledge of software configuration management, e.g. Git, CI/CD
  • Excellent working knowledge of secure software development practices

Desirable

  • Embedded Systems development using an RTOS (e.g. FreeRTOS)
  • Working with data transfer formats and connectivity protocols (https, CBOR, MQTT, REST APIs)
  • Python skills for data analysis (NumPy, pandas, Jupyter)
  • Experience of using IoT devices connected via public mobile networks.
  • Knowledge of EU MDR and FDA medical device regulations
  • Working under international regulatory standards ISO 13485, IEC 62304, ISO 14971, ISO 27001

Qualifications & Experience

Essential

  • At least 3 years of C++ in resource constrained environments

Other Requirements

  • Legally eligible to work in the UK. Please note that we are able to issue Certificates of Sponsorship to candidates already working in the UK on an unsponsored or Skilled Worker Visa, but are unable to offer sponsorship to those not already eligible to work in the UK.
  • Able to work in person in the Cambridge office at least 4 days / week (but ideally more)

Note to Applicants

  • We read all applications carefully - including your free-text answers - in evaluating your application. Please make sure you spend some time answering these questions carefully
  • Please answer questions truthfully and without using a LLM to auto-populate answers. Dishonesty is fundamentally against our values
  • We appreciate that some candidates may hesitate to apply because they may feel that they might not meet all of the required criteria or be competitive enough. If this is you, please don't shy away from applying - we would like to hear from you!
