Naimuri - Senior Software Engineer

Job Title: Naimuri - Senior Software Engineer

Location: Manchester, England, United Kingdom

About us:

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 presence in Cheltenham, London, Portsmouth and Lincoln.

Our name was chosen as an amalgamation of two Japanese words, 'not - overburden'.

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 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.

About the Role

As a Senior Software Engineer, you will lead the development of complex features that directly support our mission. You'll have the autonomy to make high‑impact 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:

• Own the Solution: You will lead the development of large, complex features from initial design to final delivery, often operating without direct guidance.
• Be an SME Champion: You'll be a subject matter expert, guiding technical debates, solving the most complex defects, and being a go‑to person for your team and the wider business.
• Enable Your Team: You'll proactively improve team efficiency, onboard new members, remove blockers, and be a force for breaking down knowledge silos.
• Mentor & Grow: You'll be a role model, actively mentoring other engineers, helping them develop their skills, and improving our standards for quality and documentation.
• Shape the Bigger Picture: You'll contribute to technical roadmaps, challenge design choices, and work with customers to identify and scope new opportunities.

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

• You thrive on owning a complex problem from the whiteboard to production.
• You enjoy breaking down large, ambiguous problems into concrete, deliverable steps.
• You're comfortable challenging the status quo and actively look for ways to improve processes, codebases, and team efficiency.
• You are comfortable considering the "big picture," including cost‑efficiency, scalability, security and performance in your designs.

This might not be the role for you if:

• You prefer a well‑defined ticket queue where you can focus purely on implementation.
• You're not interested in mentoring other engineers or participating in wider team leadership.
• You're uncomfortable with the ambiguity that comes from working on novel challenges.
