About Carebit

Carebit is a design-led, remote-first healthtech company helping hundreds of private doctors across the UK run their practices more efficiently—and delivering a better experience for their patients. We’re profitable, bootstrapped, and committed to staying remote.

We doubled revenue in 2024 and continue to grow at a rapid pace. With a growing queue of new practices ready to migrate, we’re hiring a Data Engineer to own and deliver migrations from start to finish, and improve our robust Ruby data tooling.

The role

You’ll guide new customers through migrating from their old practice management systems into Carebit. This involves cleaning, validating, and converting data (patients, bookings, invoices, etc.)—usually from structured exports or spreadsheets. You’ll communicate with customers throughout the process, helping them feel confident and supported. All key processes are well documented in our internal playbook.

A typical migration includes:

Booking a migration date and answering any customer queries
Receiving data via FTP (typically ~5GB)
Cleaning, validating, and converting data using Ruby scripts (CSV → JSON)
Writing new Ruby scripts where needed (for less structured sources)
Uploading converted data to AWS S3 and scheduling import jobs
Iterating on our tooling and processes to improve speed, reliability, and test coverage

You’ll work alongside experienced Ruby and DevOps engineers, including the original author of our migration tooling.

Requirements

Proven experience as a Data Engineer or backend developer with strong data transformation and scripting skills
Proficiency in Ruby (or ability to pick it up quickly); experience processing CSV and outputting JSON
Comfortable with Linux, bash scripting, Ansible provisioning, and remote Ubuntu environments
Familiar with both SQL and NoSQL structures (e.g. we import from MongoDB, though don’t use it internally)
Experience validating, transforming, and cleaning large datasets
Confident working with CSV/JSON, Postgres (for intermediate processing), and AWS S3
Experience building automated test suites (we use RSpec)
Excellent spoken/written English, customer-focused mindset, and calm communication style
Able to own and improve a technical function independently
Located within UTC-4 to UTC+3 (UTC+1 preferred for alignment)

Bonus points for

Formal ETL experience
AWS and Terraform knowledge
An automation-first mindset

Benefits

Competitive salary
25 days holiday/year
Async work culture with minimal meetings
Laptop, chair, and setup budget

The Future of Machine Learning Jobs: Careers That Don’t Exist Yet

Machine learning (ML) has become one of the most powerful forces reshaping the modern world. From voice assistants and recommendation engines to fraud detection and medical imaging, it underpins countless applications. ML is no longer confined to research labs—it powers business models, public services, and consumer technologies across the globe. In the UK, demand for machine learning professionals has risen dramatically. Organisations in finance, retail, healthcare, and defence are embedding ML into their operations. Start-ups in Cambridge, London, and Edinburgh are pioneering innovations, while government-backed initiatives aim to position the UK as a global AI leader. Salaries for ML engineers and researchers are among the highest in the tech sector. Yet despite its current importance, machine learning is only at the beginning of its journey. Advances in generative AI, quantum computing, robotics, and ethical governance will reshape the profession. Many of the most vital machine learning jobs of the next two decades don’t exist today. This article explores why new careers will emerge, the roles likely to appear, how today’s roles will evolve, why the UK is well positioned, and how professionals can prepare now.

Seasonal Hiring Peaks for Machine Learning Jobs: The Best Months to Apply & Why

The UK's machine learning sector has evolved into one of Europe's most intellectually stimulating and financially rewarding technology markets, with roles spanning from junior ML engineers to principal machine learning scientists and heads of artificial intelligence research. With machine learning positions commanding salaries from £32,000 for graduate ML engineers to £160,000+ for senior principal scientists, understanding when organisations actively recruit can dramatically accelerate your career progression in this pioneering and rapidly evolving field. Unlike traditional software engineering roles, machine learning hiring follows distinct patterns influenced by AI research cycles, model development timelines, and algorithmic innovation schedules. The sector's unique combination of mathematical rigour, computational complexity, and real-world application requirements creates predictable hiring windows that strategic professionals can leverage to advance their careers in developing tomorrow's intelligent systems. This comprehensive guide explores the optimal timing for machine learning job applications in the UK, examining how enterprise AI strategies, academic research cycles, and deep learning initiatives influence recruitment patterns, and why strategic timing can determine whether you join a groundbreaking AI research team or miss the opportunity to develop the next generation of machine learning algorithms.

Pre-Employment Checks for Machine Learning Jobs: DBS, References & Right-to-Work and more Explained

Pre-employment screening in machine learning reflects the discipline's unique position at the intersection of artificial intelligence research, algorithmic decision-making, and transformative business automation. Machine learning professionals often have privileged access to proprietary datasets, cutting-edge algorithms, and strategic AI systems that form the foundation of organizational competitive advantage and automated decision-making capabilities. The machine learning industry operates within complex regulatory frameworks spanning AI governance directives, algorithmic accountability requirements, and emerging ML ethics regulations. Machine learning specialists must demonstrate not only technical competence in model development and deployment but also deep understanding of algorithmic fairness, AI safety principles, and the societal implications of automated decision-making at scale. Modern machine learning roles frequently involve developing systems that impact hiring decisions, financial services, healthcare diagnostics, and autonomous operations across multiple regulatory jurisdictions and ethical frameworks simultaneously. The combination of algorithmic influence, predictive capabilities, and automated decision-making authority makes thorough candidate verification essential for maintaining compliance, fairness, and public trust in AI-powered systems.
