Senior Software Engineer - TypeScript / Next.Js / SQL

A growing technology-led business is rebuilding and modernising the core system — including billing, invoicing, reconciliation, integrations, operational workflows, reporting, customer tooling, and internal platforms.

These systems sit at the heart of the organisation and directly influence revenue, operational efficiency, customer trust, and commercial decision-making.

This role is suited to someone who enjoys solving complex operational and data problems, and who takes ownership of outcomes rather than simply delivering tickets.

Strong engineering judgement, systems thinking, and an appreciation for correctness are essential in an environment where mistakes can have meaningful downstream impact.

AI-assisted development is already central to the engineering workflow. Tools such as Claude Code and Cursor are actively used day-to-day, and senior engineers are expected to use them confidently and pragmatically.



What You’ll Be Responsible For

  • Designing and evolving business-critical systems across operations, finance, integrations, and customer workflows
  • Leading technical investigations into workflows, operational issues, integrations, and data discrepancies
  • Partnering closely with finance, operations, support, engineering teams, and customers to solve complex business problems
  • Leading technical and operational discussions with customers over calls and video meetings
  • Building systems that are accurate, auditable, explainable, scalable, and maintainable
  • Driving improvements in reliability, observability, documentation, and engineering standards
  • Using AI-assisted development tools to accelerate delivery while maintaining engineering quality and judgement
  • Helping shape technical direction, architecture, and long-term platform decisions


What They’re Looking For

Essential

  • Strong TypeScript experience across frontend and backend systems
  • Deep experience with Next.js, NestJS, and modern backend architecture
  • Strong SQL and data modelling skills, ideally PostgreSQL
  • Experience building and maintaining business-critical systems where correctness, auditability, and operational reliability matter
  • Strong understanding of distributed systems, data flows, reconciliation logic, and failure handling
  • Comfortable working through operational exceptions, edge cases, and complex integrations
  • Excellent communication skills with both technical and non-technical stakeholders

Highly Desirable

  • Go experience, particularly in backend systems, infrastructure, concurrency-heavy workloads, or performance-sensitive services
  • Experience in logistics, shipping, or supply chain operations
  • Background in billing, invoicing, payments, finance, audit, or compliance-heavy environments
  • Familiarity with cloud infrastructure, APIs, and data-heavy integrations
  • Hands-on experience with AI tooling such as Claude Code or Cursor as part of daily engineering workflows


Salary & Benefits

  • Up to £75,000 depending on experience
  • 25 days holiday + bank holidays
  • Flexible working arrangements - 3 days office / 2 days remote
  • Opportunity to shape systems critical to business operations

Where to Advertise Data Engineering Jobs in the UK (2026 Guide)

Where to advertise data engineering jobs UK in 2026: the specialist boards and channels that reach Spark, dbt, Snowflake and platform engineering talent. Data engineers occupy a distinct discipline that sits between software engineering, data science and cloud infrastructure — and the strongest candidates identify firmly with the data engineering community rather than with adjacent roles. General job boards consistently conflate data engineering with data analysis, data science and BI development, producing high application volumes but low candidate quality for specialist pipeline and platform roles. This guide, published by DataEngineeringJobs.co.uk, covers where to advertise data engineering roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Data Engineering Jobs UK 2026: What to Expect Over the Next 3 Years

Data Engineering Jobs UK 2026: roles, salaries and the trends shaping UK data engineering hiring over the next three years — Spark, dbt, lakehouse and AI. Data engineering has become one of the most strategically important disciplines in the entire technology sector — and one of the most reliably in-demand. Every organisation that wants to use data to make decisions, train AI models, personalise products, manage risk, or understand its customers depends on data engineers to build the infrastructure that makes any of that possible. Without well-designed, reliable data pipelines, the most sophisticated machine learning model is worthless and the most ambitious analytics strategy is undeliverable. That foundational importance has made data engineering hiring remarkably resilient through the technology market corrections of the past few years. Where headcount reductions fell heavily on some engineering disciplines, demand for data engineers held firm — because the work of building and maintaining data infrastructure cannot be deferred in the way that some product development can. The data keeps coming. The pipelines need to work. But the data engineering jobs market of 2026 is not simply a stable version of what it was three years ago. The discipline has undergone a series of architectural shifts — from batch to streaming, from on-premise data warehouses to cloud-native lakehouses, from hand-rolled pipelines to declarative transformation frameworks, and most recently toward AI-augmented data engineering workflows that are beginning to reshape what the role looks like in practice. The employers hiring data engineers today are asking for a meaningfully different skill set than those hiring three years ago. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which architectural patterns are becoming standard, which technologies are defining the modern data stack, and how the definition of a data engineering career is evolving toward a richer intersection of infrastructure, analytics, and AI enablement. This article breaks down what the UK data engineering jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
