Senior Kotlin Engineer

Ncounter is supporting a leading organisation within the publishing and media space as they look to strengthen their backend engineering capability. This team is responsible for building and evolving platforms that aggregate, process and distribute large-scale editorial and content datasets, enabling internal teams and external partners to access high-quality, structured information in near real time.

You will join a highly capable engineering function focused on delivering scalable backend services, working across API development and Kotlin-based microservices that power content ingestion, indexing and distribution workflows. The environment is data intensive, with a strong emphasis on performance, reliability and clean service design across a modern cloud architecture.

Key requirements:

• 3-4 years commercial experience with Kotlin, or strong Java (8/11) with a desire to transition

• 7+ years working across JVM-based backend development

• Strong experience with Spring Boot and building RESTful or GraphQL services

• Solid understanding of relational databases such as PostgreSQL or MySQL

• Experience working within BDD or TDD environments, alongside CI/CD tooling such as CircleCI

• Exposure to AWS services including Lambda, DynamoDB, SQS, RDS and CloudWatch, alongside infrastructure as code tools such as Terraform

• Familiarity with ORM frameworks such as Hibernate or JOOQ

This role will see you take ownership of key backend components within a wider content and publishing platform, contributing to the development of new services and improving existing systems that manage complex data pipelines. You will work closely with other engineers, product stakeholders and data specialists to ensure content is processed efficiently and made accessible in a consistent, scalable way.

The team places strong value on engineering best practice, collaboration and continuous improvement, offering an environment where you can have a genuine impact on the direction of the platform and the evolution of its architecture.

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

Advertising data engineering jobs in the UK requires a different approach to most technical hiring. 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.

How Many Data Engineering Tools Do You Need to Know to Get a Data Engineering Job?

If you’re aiming for a career in data engineering, it can feel like you’re staring at a never-ending list of tools and technologies — SQL, Python, Spark, Kafka, Airflow, dbt, Snowflake, Redshift, Terraform, Kubernetes, and the list goes on. Scroll job boards and LinkedIn, and it’s easy to conclude that unless you have experience with every modern tool in the data stack, you won’t even get a callback. Here’s the honest truth most data engineering hiring managers will quietly agree with: 👉 They don’t hire you because you know every tool — they hire you because you can solve real data problems with the tools you know. Tools matter. But only in service of outcomes. Jobs are won by candidates who know why a technology is used, when to use it, and how to explain their decisions. So how many data engineering tools do you actually need to know to get a job? For most job seekers, the answer is far fewer than you think — but you do need them in the right combination and order. This article breaks down what employers really expect, which tools are core, which are role-specific, and how to focus your learning so you look capable and employable rather than overwhelmed.
