Job Type: Contract/Permanent, Full-time


About Dexory

As a child, did you ever dream of building robots? We did.


At Dexory, we're developing advanced software powered by cutting-edge robots that are transforming the very face of global logistics. With infectious enthusiasm, our unique blend of disciplines work in harmony to produce results at pace. From hardware and manufacturing to software, AI and commercial, we're one team - one heart - that beats, learns and grows together.


We're only interested in the best ideas, no matter where they're from. We're doers. Game-changers. Out-of-the-box thinkers who put merit before all else. A group of ambitious and disciplined individuals who are passionate about turning theory into rubber, metal and results. Only with immense heat and pressure are diamonds formed, and our high-performance, high-reward culture isnʼt for everyone. We bend the rules. We say it as it is. We donʼt quit. We keep ego and bureaucracy in check to help our operation stay agile and performing at its peak. We're a place where careers are defined, and we'll give you all the tools youʼll need to make your mark.


This opportunity doesnʼt present itself everyday. This is your chance to be a part of something truly revolutionary. The foundations for success have been laid, but we're only just getting started. Are you ready for the fight?


We value the right attitude, humility and we're as interested in your character as we are in your talent. Please apply, even if you feel you only meet part of our listed criteria. Diversity drives innovation and we offer an international and friendly work environment with an energetic company culture.


What does this role involve?

As a Data Engineer (Perception) you will help our team handle large volumes of images used in perception and computer-vision workflows. The focus of this role is practical: simplify data handling, automate repetitive tasks and support the team with reliable tools, not introduce complexity. You will play a key role in building and maintaining lightweight data pipelines for moving, cleaning and organising large sets of images. You’ll automate repetitive or manual processes related to dataset preparation, quality checks and annotation workflows. You’ll develop Python utilities to help the team quickly filter, keep or discard images based on quality or other criteria. We’re still an early-stage company with a technically complex system, so we’re looking for a motivated individual who can help move the product forward. The ability to think on your feet, collaborate with other highly technical teams, and take an open-minded approach to problem solving are essential.


Requirements

  • 6+ years of experience shipping software products
  • Strong Python programming skills
  • Solid experience with Pandas for data manipulation
  • Experience working with large image sets
  • Excellent communication, collaboration, and teamworking skills

It Would Also Be Helpful To Have

  • Familiarity with simple image-quality heuristics or pre-processing steps
  • Experience with AWS
  • Experience with OpenCV for basic image processing

Example projects

  • Building a data processing pipeline to capture frames from multiple 3D LiDAR scanners and reconstruct a 3D environment for analysis.
  • Designing and developing a system to collect images from multiple cameras and aggregate them into one cohesive image in real-time.
  • Building a system to run real-time machine vision algorithms and ML models over high-resolution camera images.

Benefits

Starting from the interview process and continuing into your career with us, you will be working by our four Operating Principles:



  • Performance: High standards, outstanding results,
  • Impact: Big challenges, bigger results
  • Commitment: All in, every time
  • One team: One mission, shared success

Joining our team and company isn't just about expertise; it's about embracing uncertainty with ambition. We're crafting world-changing solutions, fueled by a passion to redefine what's possible. We will look for you to help create and shape the future of logistics solutions through our products, our culture and our shared vision.


You Will Also Receive

  • Private healthcare via Bupa with 24/7 medical helpline
  • Life insurance
  • Income protection
  • Pension: 4+% employee with option to opt into salary exchange, 5% employer
  • Employee Assistance Programme - mental wellbeing, financial and legal advice/support
  • 25 holidays per year
  • Full meals onsite in Wallingford
  • Fun team events on and offsite, snacks of all kinds in the office

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.
