Graduate Software Engineer – Build Technology That Moves in the Real World

Want to write code that doesn’t just sit on a screen—but powers real robots in real environments?

At Dexory, our engineers build the systems behind autonomous robots that navigate warehouses, scan inventory, and generate insights at scale. From robotics and computer vision to machine learning and cloud infrastructure, the problems we solve are complex, fast-moving, and deeply technical.

This is more than a graduate role. It’s a launchpad.

Why this role is different

From your first few weeks, you’ll be shipping production code—software that runs on robots, processes live data, and supports real operations.

Your first year is structured to accelerate your growth:

• Start in a core team aligned with your interests
• Rotate across teams every 2–3 months
• Build both depth and breadth across a modern engineering stack

By the end of the year, you won’t just understand the system—you’ll have helped build it.

If you’re excited by complex systems, real-world impact, and rapid growth, this is where your engineering career starts.

Where you could work

You’ll join one of our core teams, with rotations across others:

Autonomy
Build the systems that allow robots to safely navigate busy, real-world warehouse environments.
Think: motion planning, real-time systems, and safety-critical software.

AI / Perception
Turn raw sensor data into meaningful insights using computer vision and machine learning.
Think: ML pipelines, point cloud data, and large-scale perception systems.

Platform
Power everything behind the scenes with scalable infrastructure and developer tooling.
Think: cloud systems, CI/CD, and production reliability at scale.

What you’ll be doing

• Ship production code early—whether it’s running on robots, powering pipelines, or supporting infrastructure
• Work on systems that interact with the physical world, not just simulations
• Progress from well-defined tasks to owning features and leading small projects
• Design, build, test, and deploy software to production standards from day one
• Collaborate with engineers and cross-functional teams to deliver real-world solutions
• Contribute to technical discussions and grow into architectural thinking

What we’re looking for

You don’t need industry experience—but you do need strong fundamentals and curiosity.

You should have:

• A degree in Computer Science, Engineering, Robotics, AI/ML, Maths, Physics, or similar
• Strong foundations in Python
• Experience with Git and Linux
• Evidence of building real projects (coursework, personal projects, open source, etc.)

Depending on your interests, it’s great if you have:

• Autonomy: C++, robotics, or real-time systems
• AI / Perception: PyTorch, TensorFlow, or computer vision
• Platform: Docker, CI/CD, or cloud infrastructure

We care more about depth than ticking every box. If you’re strong in one area and motivated to learn, you’ll thrive here.

How you’ll grow

You’ll be supported from day one with structured mentorship and clear progression:

• Dedicated mentor: A senior engineer to guide your development
• Real feedback: Regular input on your code, decisions, and growth
• Access to leadership: Learn from experienced engineers across the business

Your first year:

• 3 months: Shipping independently, confident in your team’s domain
• 6 months: Owning features end-to-end, contributing to design discussions
• 12 months: Operating as a well-rounded engineer across multiple systems

Technologies you’ll work with

Depending on your team and rotations:

• Core: Python, Linux, CI/CD
• Autonomy: C++, ROS
• AI / Perception: PyTorch, TensorFlow
• Platform: Docker, Kubernetes, AWS, Golang, TypeScript, React

What you’ll gain

• Experience building production systems from day one
• Exposure to robotics, AI, and scalable infrastructure
• A fast-tracked path to becoming a confident, well-rounded engineer
• The chance to work on technology that directly impacts real-world operations

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
