Job Description

We're looking for four Embedded C++ Developers to join an in-house backend engineering team working on a highly regulated, safety-critical medical technology product.

You'll own a self-contained area of the application, taking work from initial design through to merged, tested and documented code. Depending on your experience and the team's needs, this could include areas such as alarms, patient data persistence, device supervision and start-up, session management or service functionality.

You'll work closely with the Software Architect and engineers responsible for surrounding components, while taking ownership of delivery within your area.

This role is well suited to an experienced Embedded C++ Engineer who has worked on Linux-based safety-critical, mission-critical or highly regulated products and is comfortable working with formal quality processes, static analysis, code coverage and rigorous testing requirements.


What You'll Be Working On

Your work could span a number of areas of the embedded application, including:

Alarms

  • Developing technical alarm conditions based on hardware and operating system telemetry.
  • Working with signals including battery, temperature, clock, power faults and telemetry quality.
  • Implementing patient sensor, signal quality and external monitoring alarms.
  • Working with hardware alarm interfaces including mute functionality, alarm-level verification and alarm telemetry.
  • Building robust fault handling and recovery mechanisms.

Start-Up, Self-Test & Supervision

  • Developing power-on checks covering logging, hardware compatibility, GPU checks and system self-tests.
  • Implementing fail-safe states and fault management.
  • Integrating watchdog and system supervision mechanisms.
  • Supporting interrupted-session detection and recovery.
  • Developing logging, audit logging and log rotation functionality.
  • Working with OS telemetry including power button and storage health monitoring.

Patient Data Persistence & Presentation

  • Developing storage interfaces supporting atomic and checksummed writes.
  • Managing reading, deletion and session listing across fixed storage partitions.
  • Building patient-data packaging, queueing, flushing, retention and retrieval functionality.
  • Supporting data back-fill and historic data presentation.
  • Developing versioned interfaces between backend data and the GUI.

Session Lifecycle, Power-Down & Service

  • Managing patient sensor and session lifecycles.
  • Supporting session metadata, recovery and graceful shutdown.
  • Developing power-button handling and controlled power-down functionality.
  • Supporting USB data export functionality.
  • Working with service tools and device service handlers.
  • Supporting software updates, confirmation and rollback.
  • Implementing log extraction and audit logging.

Essential Skills & Experience

  • Strong experience developing modern C++17 applications on embedded Linux.
  • Strong understanding of RAII, fixed-width types, std::atomic, multithreading and lock-free or bounded queues.
  • Experience developing software where deterministic behaviour and reliability are critical.
  • Experience with allocation-free or low-allocation runtime environments, including pre-allocated memory and fixed-capacity containers.
  • Experience with ports-and-adapters / hexagonal architecture, interfaces and dependency injection.
  • Strong Linux systems integration experience, including services, watchdogs and system-level fault management.
  • Experience with IPC and serialisation technologies such as FlatBuffers, Unix-domain sockets or named pipes.
  • Experience with CMake, automated testing and CI/CD pipelines.
  • Experience with cross-compilation, ideally for aarch64 platforms.
  • Strong experience with unit testing, code coverage and quality gates.
  • Comfortable working within formal engineering processes, including peer review, traceable changes and documented design decisions.
  • Experience working on safety-critical, mission-critical or highly regulated software.

Desirable Skills & Experience

  • Experience developing medical devices or other safety-critical systems.
  • Knowledge of IEC 62304, ISO 13485 or similar regulated software development standards.
  • Experience with medical alarm systems or other alarm and fault-management systems.
  • Understanding of IEC 60601-1-8 or equivalent safety standards.
  • Experience working with state-machine-driven supervisors and fault-management systems.
  • Experience with NVIDIA Jetson, CUDA or GPU-accelerated processing.
  • Experience with Yocto and embedded Linux board-support packages.
  • Experience with systemd, sd_notify, D-Bus and journald.
  • Experience with OpenSSL, TensorRT or similar external technologies.
  • Experience using Docker for development environments.
  • Experience with GoogleTest, behaviour-driven testing or Gherkin.
  • Python experience for tooling and deployment scripts.
  • Experience contributing to software FMEA activities and implementing risk controls.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be.

We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.
