Python Software Developer jobs in United Kingdom

Job Title: Software Engineer

Job Location: Salford Quays, Manchester

Job Type: Permanent, Fulltime

Job ID: 19265

We’ve just had our tenth birthday, having grown from a little‑known tech start‑up into a community of 180 people, mostly based in Salford, Greater Manchester. We also have a significant presence in Cheltenham and London.

Our name was chosen as an amalgamation of two Japanese words, to reflect our ethos:

This principle applies to every aspect of our organisation from technology, process and infrastructure, through to people, culture and leadership. People and culture are at the heart of Naimuri, so that collectively, we can realise our mission of making the UK a safer place to be.

We work in an Agile‑first environment that values transparency, collaboration, and continuous improvement. While every team has its own rhythm, you can expect:

• A Culture of Enablement: Our goal is to remove blockers. You'll be empowered to make decisions and given the tools you need to get things done.
• Focus on Quality: We take pride in our work. You'll be part of a culture that values well‑written, maintainable code, and your work will serve as a "definitive example" for others.
• Active Collaboration: You'll work closely with Platform Engineers, Delivery Leads, and Product Owners, helping to manage and maintain your own infrastructure (e.g., Kubernetes) and build automated delivery pipelines (using GitLab).

At Naimuri, we work on a variety of projects that range in length from a few weeks to 5+ years. Here are some things we’ve worked on recently that give a sense of the work we do:

• Building a data analytics tool using a Neo4J graph database.
• A DevOps platform to support 3000 users.
• Processing digital forensic data to enable search and insight generation.
• A search and reporting system backed by an ElasticSearch cluster.
• A custom workflow tool using Camunda, with a React/TS front‑end
• An AI assurance capability
• Orchestrating a data pipeline and designing specialist metrics for the evaluation of the performance of LLMs in different contexts.

As a Software Engineer at Naimuri, you'll have the autonomy to make impactful decisions, the space to solve difficult technical challenges, and the support of a strong engineering community.

This role is about more than just your own code; it's about making the whole team better. We'll look to you to:

• Continuously build in-depth knowledge, apply design patterns, and use appropriate tools to solve complex technical issues.
• Proactively find and own solutions to improve team processes and efficiency, and actively collaborate in team meetings.
• Engage in design debates, constructively challenge solutions, identify technical risks, and proactively create/update useful documentation.

If the following describes the way you work, then I’d really like to speak to you:

• You enjoy breaking down ambiguous problems into concrete, deliverable steps, and take pride in implementing a high‑quality solution.
• You instigate collaboration, putting the team first and doing what needs doing to help them succeed.
• You are comfortable challenging the status quo and look for ways to improve processes, codebases, and team efficiency.

This might not be the role for you if:

• You are uncomfortable with owning the delivery tasks that may require you to seek out cross‑team collaboration or guidance.
• You are not interested in proactively sharing your knowledge or supporting the development of other team members.
• You're uncomfortable with the ambiguity that comes from working on novel challenges

Continuous Personal Development, or Personal Kaizen, is a core part of Naimuri's culture, ensuring everyone has the opportunity to develop in a transparent and supportive environment.

• You will be assigned a Mentor, usually outside of your team, who can help guide and support you on your development journey.
• Naimuri actively encourages training, through internal knowledge sharing and external courses. You are empowered to identify and pursue opportunities for further training.
• We have a Naimuri progression framework, which recognizes that continuous personal development drives greater proficiency and depth in skills, roles, knowledge, or leadership. It provides a clear direction for growth and reinforces achievements that support your Personal Kaizen.

Naimuri pays competitively within the industry based on your role's base location rates. The salary for this position is dependent upon your experience. We assess seniority relative to the team at Naimuri during the interviewing process.

A full time working week is 37.5 hours and you have flexibility over when you give that time. We also offer part-time working which can be discussed during the recruitment process.

Our core hours are 10:00am - 3:00pm and our office is open between 7:30 - 18:00, Monday to Friday. Most teams have agreed ‘in office’ days to enable collaboration. Depending on the project, you may also be required to travel to a local customer site or occasionally to other locations in the UK.

• Flexible/Hybrid working options
• Performance bonus
• Company bonus
• Pension matched 1.5x up to 10.5%
• AXA group 1 medical cover
• Holiday purchase/buy‑back scheme
• Cycle to work scheme
• Car benefit scheme

We are committed to building an inclusive, safe and supportive environment that allows everyone to do their best work, so we strongly encourage candidates of all different backgrounds and identities to apply. We can of course support any accessibility or neurodiversity requirements that you may need during the recruitment process.

We want to ensure that you feel comfortable and confident when interviewing with us. To help you prepare, our recruitment team will be happy to discuss the process in more detail with you when you apply.
