Requirements


  • Python Expertise:Strong experience with FastAPI, Pydantic.
  • Cloud & Infra:Proficiency with AWS (Lambda, S3, ECS, EventBridge, RDS, OpenSearch) and Terraform.
  • Event-Driven Systems:Hands-on experience with event-driven architectures (SNS/SQS, Kafka, Redis Streams).
  • Workflow Orchestration:Knowledge of long-running workflows (Step Functions, Temporal, Airflow).
  • Real-Time Systems:Understanding of WebSockets, SSE, and related protocols.
  • Data Engineering:Experience designing ETL pipelines and handling structured/unstructured data.
  • Security & Reliability:Strong grasp of cloud security, IAM, and infrastructure resilience.
  • Problem-Solving:Proven ability to debug and optimise distributed systems.


Nice to Have


  • AI Scaling:Experience running AI/ML workloads in production (batch vs. real-time inference, GPU optimisation).
  • Vector Databases:Familiarity with vector search and retrieval systems.
  • Kubernetes:Hands-on experience managing and deploying Kubernetes clusters.
  • Agentic AI:Experience with autonomous AI systems.
  • Legal Tech Background:Knowledge of legal industry workflows and automation.


Why Join?


If you want to ship features daily in a fast-paced, high-impact environment. Work at the forefront of AI in legal tech, solving complex challenges & join a team of ambitious, mission-driven engineers redefining the industry. This is perfect for you!


  • 26 Days Holiday
  • Significant Equity Options
  • Company Pension Contributions
  • Remote Working - Office based is possible, but they trust their teams to work productively and collaboratively where it suits them best. They do meet up every 8-10 weeks, purely as they like seeing one another - travel expenses etc will be covered.

Rural-Remote Machine Learning Jobs: Finding Balance Beyond the Big Cities

Over the past decade, machine learning (ML) has transformed from a niche research domain into a pervasive technology underpinning everything from recommendation systems and voice assistants to financial forecasting and autonomous vehicles. Historically, the UK’s major tech hubs—particularly London—have been magnets for top ML talent and corporate headquarters. However, remote work has become mainstream, and many ML professionals are realising they can excel in their field while living far beyond the city limits. At MachineLearningJobs.co.uk, we’ve observed a growing interest in positions that allow for a rural lifestyle or a coastal environment, often reflected in search terms like “ML remote countryside” or “tech jobs by the sea.” This surge is no coincidence. Flexible work policies, better rural broadband, and the nature of machine learning tasks—much of which can be done through cloud platforms—are bringing new opportunities to those who wish to swap urban hustle for fresh air and scenic views. Whether you’re a data scientist, ML engineer, researcher, or product manager, a rural or seaside move could reinvigorate your work-life balance. In this article, we’ll unpack why rural-remote ML jobs are on the rise, how you can navigate the challenges of leaving the city, and what you need to do to thrive in a machine learning career beyond the M25. If you’ve dreamt of looking up from your laptop to rolling fields or ocean waves, keep reading—your rural ML role might be closer than you think.

Quantum-Enhanced Machine Learning—Propelling AI into the Next Frontier

Machine learning (ML) has revolutionised how we interpret data, build predictive models, and create intelligent applications. From recommendation engines and self-driving cars to advanced genomics and natural language processing, ML solutions are integral to nearly every corner of modern life. However, as data complexity and model size continue to skyrocket, the computational demands placed on ML systems grow in tandem—often pushing even high-performance classical computers to their limits. In recent years, quantum computing has emerged as a tantalising solution to these challenges. Unlike traditional digital systems, quantum computers exploit quantum mechanics—superposition and entanglement—to process information in ways that defy conventional logic. As these machines mature, they promise exponential speed-ups for certain tasks, potentially reshaping how we approach AI and data-intensive challenges. What does this mean for machine learning? Enter quantum-enhanced ML, a new frontier where quantum processors and classical ML frameworks unite to accelerate model training, tackle high-dimensional data, and solve complex optimisation tasks more efficiently. In this article, we will: Unpack the current state of machine learning, highlighting key bottlenecks. Provide a concise overview of quantum computing—why it’s radical and how it differs from classical technology. Examine potential breakthroughs in quantum-enhanced ML, including real-world use cases and technical approaches. Explore the roles and skill sets that will define this quantum-AI era, with guidance on how to prepare. Discuss the roadblocks (like hardware maturity and ethical concerns) and how they might be addressed in the years to come. If you’re a machine learning engineer, data scientist, or simply an AI enthusiast fascinated by the next wave of computational innovation, read on—quantum computing could become an integral part of your future toolkit, opening up job opportunities and reimagining what ML can achieve.
