Think rapid capability deployment, deployed hardware environments, sensors, and robotics - the kind of engineering problems that push you to grow. You'll own code releases and deployments, support operational systems, and collaborate across disciplines to drive agile best practice into real-world solutions. ## What You'll Be Doing You'll work closely with product owners and fellow engineers across the full delivery lifecycle - from architecture discussions to production deployments. Day to day, that means contributing to agile ceremonies (Scrum, Kanban or SAFe), participating in code reviews, working with quality engineers to uphold high standards, and troubleshooting operational systems when it counts. This is a collaborative, technically ambitious environment where your voice matters and your ideas get heard. ## What We're Looking For You'll have a degree in a STEM subject, or equivalent practical experience. Beyond that, we're interested in engineers who are curious, proactive, and genuinely energised by solving hard problems. You'll be familiar with some combination of the following - we don't expect expertise across everything, but we do want depth in some areas and a hunger to learn the rest. Languages: Python, Java, Rust, or JavaScript Cloud: AWS (primary), with Azure or GCP experience a bonus Containerisation & Virtualisation: Docker or Podman, Kubernetes, and ideally some exposure to GPU containerisation (NVIDIA Container Toolkit, Run:AI) Architecture: Microservices, serverless, edge compute, RESTful APIs, Protobuf/gRPC, and stream-based pub/sub systems including Kafka and MQTT DevSecOps: Git, CI/CD pipelines (e.g. GitLab), Infrastructure as Code (Terraform, Puppet, Ansible), and Linux shell scripting As important as the technical profile is the person behind it. You'll communicate clearly with colleagues at all levels, thrive in a team, and take ownership of your work with a solutions-first mindset. ## What's on Offer Alongside a competitive salary, you'll have access to a flexible benefits package spanning health and wellbeing, financial protection, and lifestyle perks. You'll join a genuinely inclusive organisation that invests in its people and its technology in equal measure - having doubled in size over the last four years, the growth here is real and the opportunities that come with it are too. There's also a thriving internal community of technical groups where engineers come together around shared interests, tools, and ideas. It's the kind of place where intellectual curiosity is encouraged, not just tolerated. This role requires the ability to obtain UK Security Clearance. If you're ready to work on problems that matter, with people who take pride in what they build, we'd love to hear from you

Southampton (hybrid, 1 day per week in office)
£73-75k + 10% Bonus, 8% Pension, Private Medical.

This role cannot offer Visa Sponsorship.

Your new company
I’m recruiting exclusively for a globally connected business operating at the heart of international trade. Their name is known worldwide and you’ll work within a subsidiary building software that directly determines whether goods can move through the country’s ports.

With significant investment underway to modernise and evolve their platforms, including the use of AI in production, they are looking for a Lead Java Developer to play a key role in driving hands-on technical delivery and engineering standards for a technical team of 6.

It’s the best of both worlds, security of a multi-national with the strong collaboration and interaction of an SME.

Your new role
This is a genuinely balanced leadership role, sitting 50/50 between hands-on engineering and people management.
The environment is heavily backend focused today, centred around Java and Spring-based systems, but there is a clear roadmap towards a more full-stack capability over time. You’ll therefore have the opportunity to influence how the team evolves technically and can really make your stamp on the role.

There is also a strong forward-looking element to the role. The organisation is exploring greater adoption of cloud technologies, particularly within Azure, as well as early-stage use of AI both in internal tooling and longer-term product capability. You’ll have the opportunity to contribute to these discussions and add these skills to your portfolio commercially.

You’ll work closely with architecture and senior stakeholders, taking technical direction and translating it into clear, actionable delivery for your team. A big part of the role is bringing structure, clarity and consistency, ensuring engineering best practice is followed and continuously improved. This includes championing clean code, driving development standards and embedding scalable, maintainable approaches across the team.

What you’ll need to succeed
You’ll be an existing Lead or Senior Java Developer with a background in Spring-based development. driving engineering improvements, best practice, improving code quality and helping move teams forward.

You’ll lead technical delivery whilst remaining close enough to the code to guide decisions for a team (minimum 3 Engineers, ideally 6). Strong stakeholder engagement is key, particularly the ability to take direction from architecture and clearly articulate that to engineering teams.

You’ll be confident across backend systems, API development and database interaction (Oracle / SQL), with an awareness of how modern DevOps, CI/CD, cloud and emerging technologies fit into the wider landscape.

Exposure to Azure or cloud-based environments would be beneficial, as would any experience applying AI in a practical setting, whether through tooling, integrations or early-stage product features.

What you’ll get in return
You’ll be joining a business where the systems you build have real-world impact at scale. This is an opportunity to influence both the technical direction and the culture of a team, within an organisation that is actively investing in its technology capability.

You will also benefit from a hybrid working model, a guaranteed 10% bonus, 8% pension march, private healthcare, life assurance and 25 days holiday plus bank holidays.

What you need to do now
At Hays Technology, we are shaping the future of recruitment. The rapid adoption of cloud, which is making customer interfaces more engaging and creating a seamless engagement with businesses, means that from the foundation of your organisation up, software developers are critical to success. As the competition for talent grows, we’re ready and waiting to help developers really make an impact on organisations, so talk to us today. We are Hays Technology.

The Role You'll be part of a team delivering software solutions that leverage the latest in machine learning, edge compute, and DevOps automation. Think rapid capability deployment, deployed hardware environments, sensors, and robotics - the kind of engineering problems that push you to grow. You'll own code releases and deployments, support operational systems, and collaborate across disciplines to drive agile best practice into real-world solutions. What You'll Be Doing You'll work closely with product owners and fellow engineers across the full delivery lifecycle - from architecture discussions to production deployments. Day to day, that means contributing to agile ceremonies (Scrum, Kanban or SAFe), participating in code reviews, working with quality engineers to uphold high standards, and troubleshooting operational systems when it counts. This is a collaborative, technically ambitious environment where your voice matters and your ideas get heard. What We're Looking For You'll have a degree in a STEM subject, or equivalent practical experience. Beyond that, we're interested in engineers who are curious, proactive, and genuinely energised by solving hard problems. You'll be familiar with some combination of the following - we don't expect expertise across everything, but we do want depth in some areas and a hunger to learn the rest. Languages: Python, Java, Rust, or JavaScript Cloud: AWS (primary), with Azure or GCP experience a bonus Containerisation & Virtualisation: Docker or Podman, Kubernetes, and ideally some exposure to GPU containerisation (NVIDIA Container Toolkit, Run:AI) Architecture: Microservices, serverless, edge compute, RESTful APIs, Protobuf/gRPC, and stream-based pub/sub systems including Kafka and MQTT DevSecOps: Git, CI/CD pipelines (e.g. GitLab), Infrastructure as Code (Terraform, Puppet, Ansible), and Linux shell scripting As important as the technical profile is the person behind it. You'll communicate clearly with colleagues at all levels, thrive in a team, and take ownership of your work with a solutions-first mindset. What's on Offer Alongside a competitive salary, you'll have access to a flexible benefits package spanning health and wellbeing, financial protection, and lifestyle perks. You'll join a genuinely inclusive organisation that invests in its people and its technology in equal measure - having doubled in size over the last four years, the growth here is real and the opportunities that come with it are too. There's also a thriving internal community of technical groups where engineers come together around shared interests, tools, and ideas. It's the kind of place where intellectual curiosity is encouraged, not just tolerated. This role requires the ability to obtain UK Security Clearance. If you're ready to work on problems that matter, with people who take pride in what they build, we'd love to hear from you.

If you are looking to progress a career in computer programming or web development, then this training and placement programme is made for you?

Skills shortages in the IT sector are driving the need for qualified, entry-level career seekers and career changers.

All you need is a desire to work hard and invest some time and money in yourself to build the foundations for a new career.

We help you start your career journey in programming by firstly ensuring you have the necessary industry recognised certifications and skills required to build a career.

We ensure you market yourself properly through a structured career driven cv and LinkedIn profile highlighting your skills, any experience, and relevant transferable skills from other roles.

Finally, our tutors will help you create a credible portfolio to demonstrate your skills and abilities to potential new employers.

We have many years of experience in helping graduates find their first roles in top UK companies and organisations who need to employ entry-level qualified programming staff that can hit the ground running with up-to-date skills gained from this programme.

The programme is specifically designed for individuals with none or limited experience but a real desire to start a career. Therefore, please do not apply if you are already an experienced programmer.

Whether you are working full-time, part-time or are unemployed, this package has the flexibility to be completed at a pace that suits you and can be completed in as little as a few weeks or a few months (see steps 1 to 4 below). Study timings are approximate and assume you can study for a minimum 5 hours per week. Training times will be reduced if you are able to invest more time each week.

Stage 1 Learn HTML and CSS ( up to 12 weeks)

The first step is completing a selection of professional and industry-recognised courses. We have carefully selected these courses to give you the most out of both your learning and employment journey.

JavaScript forms the foundation of almost everything you see on the Internet. Therefore, this is an essential addition language in building your programming and development foundation.

Python is a highly versatile programming language and due to its relatively easy to understand commands now one of the most common programming languages used. You can use it for both small and complex tasks, and it is used across many different industries broadening your scope of opportunity.

Step 3 - Building a Portfolio Website Project (1 week)

Your tutor will provide you with some exercises and guidelines to help you build your own personalised portfolio. Having a strong portfolio to which demonstrates and showcases your range of skills and ability is essential within a programming career.
