For decades, the NHS has struggled with fragmented systems that make simple tasks feel impossible. We’re changing that by building a single, system-wide platform that connects everyone through communication. What started as a way for GPs to text a patient has now evolved into an all-in-one digital toolkit used by 98% of GP practices. Our platform now powers [Total Triage](https://www.accurx.com/primary-care) to manage patient demand, and [Self-Book,](https://www.accurx.com/booking) which lets patients schedule their own appointments in seconds. We’ve automated routine care with [Patient Questionnaires](https://www.accurx.com/questionnaires) for long-term conditions, while [Accumail](https://www.accurx.com/accumail) finally allows staff-to-staff communication to happen instantly across different care settings. We’re now pushing the boundaries of the consultation itself with [Accurx Scribe](https://www.accurx.com/scribe), our AI-powered note-taker that drafts medical notes in real-time. The team We are a mission-driven team of 80 engineers based in London and the surrounding areas, united by the challenge of fixing healthcare communication. We are innovating for the NHS at a scale and depth that has never been done before, solving the real-world problems that stand between millions of patients and the care they need. We are a highly cross-functional group where engineering, product, data, and security collaborate as true peers. We foster a low-ego, high-impact environment that values expertise and new ideas, maintaining the high standards required to build and scale a national healthcare communication platform. As a Senior Machine Learning Engineer, you'll join our Triage Intelligence team — a high-impact, cross-functional group of software engineers, Data Scientists, clinicians, and a Principal Product Manager. The team builds the intelligence that powers how Accurx understands healthcare communication across the entire product suite, with a current mission to interpret patient healthcare requests and enable fast, informed decisions about the next step in a patient's care. Challenges you’ll solve... - You will take ownership of the end-to-end technical design of ML systems - from data ingestion and training pipelines through to deployment and real-time monitoring - ensuring AI features are performant, observable, and easy to debug. - You will act as the primary technical partner to our Data Scientists, evolving experimental code into high-quality, extensible library modules and building reusable components that improve developer efficiency and reduce cycle times across the team. - You will translate complex clinical and product objectives into efficient computational tasks, selecting the right tools - whether Deep Learning, NLP, or off-the-shelf - and making smart build-vs-buy trade-offs that align with Accurx's long-term technical goals. - You will help turn one-off experiments into repeatable platform capabilities, building models and systems that can be adopted by other Accurx product teams and proactively resolving cross-team dependencies as new, more efficient AI models are rolled out. You should apply if... - You have extensive experience with a variety of ML techniques (e.g. Transformer-based NLP, Deep Learning, Tree-based methods, Bayesian modelling) and the ability to select the right tool, not just the trendiest one, for a clinical problem. - You have a proven track record of taking models from a Jupyter notebook to a high-availability production environment, managing everything from data versioning to model serving. - You have mastery of a production-grade language (e.g. Python, C#, or Go), with a focus on writing extensible, modular libraries that other teams can adopt. - You have experience defining both offline metrics (how the model performs in training) and online metrics (how the model impacts real-world user behaviour and triage outcomes). - You bring collaborative rigour to design and code reviews, surfacing erroneous assumptions before they reach production, and can preemptively identify technical risks — such as data leakage or hardware constraints — before they jeopardise the product roadmap. Bonus points if you have… - Experience working with sensitive, regulated data (GDPR, HIPAA) and implementing privacy-first techniques like differential privacy or secure data handling. - Familiarity with infrastructure-as-code tools like Terraform, Kubernetes, or MLOps platforms such as SageMaker or Vertex AI. - Hands-on experience fine-tuning LLMs, prompt engineering, or managing the latency and cost trade-offs of large language models at scale. What’s in it for me? You'll be joining an established but fast-growing Tech for Good movement, where we're led by our [Principles](https://www.notion.so/accurx/How-we-work-Accurx-Principles-211640edee304821b4480d3f9c30e051) and our [mission](https://accurx.notion.site/Mission-and-Vision-fe9b12ff78bd4a7996682fc5c09c2d8e) to fix healthcare communication. - £115,000 - £135,000 salary + share options up to £30,000 - [Benefits to suit you:](https://accurx.notion.site/Perks-Benefits-f1e9148b71be486791aa2c503e5d775a?pvs=74)adjust your healthcare cover, your pension or life insurance, whatever stage you’re at in life - Flexible working: We are an office first culture and ask that you’re in our (dog-friendly) Shoreditch office 3 days a week, with core hours of 10am - 4pm - Time off: You’ll get 28 days of holiday (plus bank holidays) and up to 4 weeks to work from anywhere per year - Family matters: We offer enhanced parental leave, fertility support and parental loss support - We have our very own Chef!
