Data Engineer (Perception)


Location: Onsite, Wallingford, Oxfordshire
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

How to Write a Data Engineering Job Ad That Attracts the Right People

Data engineering is the backbone of modern data-driven organisations. From analytics and machine learning to business intelligence and real-time platforms, data engineers build the pipelines, platforms and infrastructure that make data usable at scale. Yet many employers struggle to attract the right data engineering candidates. Job adverts often generate high application volumes, but few applicants have the practical skills needed to build and maintain production-grade data systems. At the same time, experienced data engineers skip over adverts that feel vague, unrealistic or misaligned with real-world data engineering work. In most cases, the issue is not a shortage of talent — it is the quality and clarity of the job advert. Data engineers are pragmatic, technically rigorous and highly selective. A poorly written job ad signals immature data practices and unclear expectations. A well-written one signals strong engineering culture and serious intent. This guide explains how to write a data engineering job ad that attracts the right people, improves applicant quality and positions your organisation as a credible data employer.

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

If you are applying for data engineering jobs in the UK, maths can feel like a vague requirement hiding behind phrases like “strong analytical skills”, “performance mindset” or “ability to reason about systems”. Most of the time, hiring managers are not looking for advanced theory. They want confidence with the handful of maths topics that show up in real pipelines: Rates, units & estimation (throughput, cost, latency, storage growth) Statistics for data quality & observability (distributions, percentiles, outliers, variance) Probability for streaming, sampling & approximate results (sketches like HyperLogLog++ & the logic behind false positives) Discrete maths for DAGs, partitioning & systems thinking (graphs, complexity, hashing) Optimisation intuition for SQL plans & Spark performance (joins, shuffles, partition strategy, “what is the bottleneck”) This article is written for UK job seekers targeting roles like Data Engineer, Analytics Engineer, Platform Data Engineer, Data Warehouse Engineer, Streaming Data Engineer or DataOps Engineer.

Neurodiversity in Data Engineering Careers: Turning Different Thinking into a Superpower

Every modern organisation runs on data – but without good data engineering, even the best dashboards & machine learning models are built on sand. Data engineers design the pipelines, platforms & tools that make data accurate, accessible & reliable. Those pipelines need people who can think in systems, spot patterns in messy logs, notice what others overlook & design elegant solutions to complex problems. That is exactly why data engineering can be such a strong fit for many neurodivergent people, including those with ADHD, autism & dyslexia. If you’re neurodivergent & considering a data engineering career, you might have heard comments like “you’re too disorganised for engineering”, “too literal for stakeholder work” or “too distracted for complex systems”. In reality, the traits that can make traditional office environments hard often line up beautifully with data engineering work. This guide is written for data engineering job seekers in the UK. We’ll cover: What neurodiversity means in a data engineering context How ADHD, autism & dyslexia strengths map to common data engineering tasks Practical workplace adjustments you can request under UK law How to talk about your neurodivergence in applications & interviews By the end, you’ll have a clearer sense of where you might thrive in data engineering – & how to turn “different thinking” into a genuine professional superpower.
