Overview

Design and implement scalable APIs and backend services, primarily in Scala, to integrate ML models into production systems and deliver personalised experiences. Real time data processing and gRPC microservices (Typelevel stack). Take end-to-end ownership of services, from development to production operations. Optimising the performance of the application in the cloud environments. Creating/improving automated pipelines that support our Continuous Delivery process. Build, scale and maintain large scale cloud-based services. Work closely with data scientists, ML engineers, and product teams to align technical solutions with business goals. Refining the team processes to continuously integrate and working towards a continuously deliverable application. Championing best practices to develop clean, resilient code that performs at serious scale. Coaching and providing feedback to fellow developers.


Responsibilities

  • Design, implement, and maintain production-grade APIs and backend services, including responsibility for reliability and performance.
  • Build and operate real-time data processing and gRPC microservices (Typelevel stack).
  • Take end-to-end ownership of services from development through production operations.
  • Optimise application performance in cloud environments and manage deployments.
  • Create, scale, and maintain large-scale cloud-based services.
  • Develop and improve automated CI/CD pipelines and related tooling.
  • Collaborate with data scientists, ML engineers, and product teams to align technical solutions with business goals.
  • Refine team processes to enable continuous integration and delivery of applications.
  • Champion best practices to develop clean, resilient code that performs at scale.
  • Coach and provide feedback to fellow developers.

Qualifications

  • Strong software engineering skills with experience in Scala, ideally the Typelevel stack (bonus if you have exposure to Golang and Python).
  • Interest in machine learning, personalization systems and cloud technology.
  • Experience designing, implementing, deploying, and maintaining production-grade APIs and backend services with reliability and on-call support responsibilities.
  • Hands-on experience with data processing frameworks and distributed systems for ingesting, processing, and storing large-scale datasets, with understanding of scalability, fault tolerance, and performance considerations.
  • Practical experience with modern software development practices, including automated CI/CD pipelines, containerisation (e.g., Docker), and deploying applications to cloud environments (e.g., AWS or GCP).
  • Ability to collaborate effectively across teams and communicate technical concepts clearly.
  • Problem-solving mindset and eagerness to learn new technologies and approaches; ability to challenge technical choices, architectures, tools, and processes.

Machine Learning Jobs for Career Switchers in Their 30s, 40s & 50s (UK Reality Check)

Are you considering a career change into machine learning in your 30s, 40s or 50s? You’re not alone. In the UK, organisations across industries such as finance, healthcare, retail, government & technology are investing in machine learning to improve decisions, automate processes & unlock new insights. But with all the hype, it can be hard to tell which roles are real job opportunities and which are just buzzwords. This article gives you a practical, UK-focused reality check: which machine learning roles truly exist, what skills employers really hire for, how long retraining realistically takes, how to position your experience and whether age matters in your favour or not. Whether you come from analytics, engineering, operations, research, compliance or business strategy, there is a credible route into machine learning if you approach it strategically.

How to Write a Machine Learning Job Ad That Attracts the Right People

Machine learning now sits at the heart of many UK organisations, powering everything from recommendation engines and fraud detection to forecasting, automation and decision support. As adoption grows, so does demand for skilled machine learning professionals. Yet many employers struggle to attract the right candidates. Machine learning job adverts often generate high volumes of applications, but few applicants have the blend of modelling skill, engineering awareness and real-world experience the role actually requires. Meanwhile, strong machine learning engineers and scientists quietly avoid adverts that feel vague, inflated or confused. In most cases, the issue is not the talent market — it is the job advert itself. Machine learning professionals are analytical, technically rigorous and highly selective. A poorly written job ad signals unclear expectations and low ML maturity. A well-written one signals credibility, focus and a serious approach to applied machine learning. This guide explains how to write a machine learning job ad that attracts the right people, improves applicant quality and strengthens your employer brand.

Maths for Machine Learning Jobs: The Only Topics You Actually Need (& How to Learn Them)

Machine learning job adverts in the UK love vague phrases like “strong maths” or “solid fundamentals”. That can make the whole field feel gatekept especially if you are a career changer or a student who has not touched maths since A level. Here is the practical truth. For most roles on MachineLearningJobs.co.uk such as Machine Learning Engineer, Applied Scientist, Data Scientist, NLP Engineer, Computer Vision Engineer or MLOps Engineer with modelling responsibilities the maths you actually use is concentrated in four areas: Linear algebra essentials (vectors, matrices, projections, PCA intuition) Probability & statistics (uncertainty, metrics, sampling, base rates) Calculus essentials (derivatives, chain rule, gradients, backprop intuition) Basic optimisation (loss functions, gradient descent, regularisation, tuning) If you can do those four things well you can build models, debug training, evaluate properly, explain trade-offs & sound credible in interviews. This guide gives you a clear scope plus a six-week learning plan, portfolio projects & resources so you can learn with momentum rather than drowning in theory.
