Junior Software Engineer jobs in United Kingdom

Due to progression, this role exists to replace a senior engineer within a well-established software company operating in the highly regulated energy sector.

Circa £56,000 + up to 15% bonus | Hybrid (2 days per month onsite, Southampton)

The software you'll work on is business critical. It must be reliable, auditable, and able to stand up to regulatory scrutiny. That shapes how engineering is done here: considered design, well-structured database development, and a focus on doing things properly rather than quickly.

If you're an Oracle engineer ready to take on more responsibility, mentor others, and work in an environment where engineering discipline matters, this role is designed for you.

You'll join a software-led organisation, contributing to the design, development, and ongoing improvement of commercial systems used within a regulated energy environment. Your work will include:

• Developing and maintaining Oracle database solutions
• Writing and optimising PL/SQL for performance, reliability, and maintainability
• Building and supporting ETL processes for data integration and reporting
• Contributing to data design decisions and agreed technical standards
• Reviewing work and helping raise engineering quality across the team
• Supporting reliable releases in a controlled, production environment

You’ll report directly to a Principal Software Engineer and work alongside experienced engineers who value clarity, quality, and pragmatic problem-solving.

This is not a people‑management role. Seniority is demonstrated through:

• Sound technical judgement in database and data‑centric systems
• Ownership of complex pieces of work
• Mentoring and supporting less‑experienced engineers
• Leading by example in code quality, testing, and delivery

It's well suited to someone who may not yet hold a senior title but is already operating at that level and ready to step up.

• Commercial experience with Oracle database development
• Strong PL/SQL skills
• Experience designing or supporting ETL processes
• Experience working on production systems in a regulated or structured environment
• A disciplined approach to testing, data quality, and reliability

• Python experience, particularly for APIs or integration work

• Hybrid role with 2 days per month onsite
• Office location: Southampton, Hampshire
• Candidates must be within a 2‑hour commute

This is non‑negotiable and intended to ensure effective collaboration when required.

• Circa £56,000 base salary
• Bonus up to 15% (personal and company performance)
• 25 days' annual leave plus bank holidays
• Pension scheme (4% employer contribution when you contribute 5%)
• Health care scheme (including dental and eye care)
• EV car scheme (terms apply)
• Free onsite gym
• Employee Assistance Programme and wellbeing support
• Paid volunteering day each year

If you're an Oracle engineer looking to step into a senior‑level role, working on meaningful systems in a regulated environment, this is worth a conversation.
