We’re building a team of engineers passionate about software craftsmanship, quality, and continuous improvement. As an Associate Software Engineer, you’ll contribute to the software that powers indices trusted by financial institutions worldwide, working alongside experienced engineers who will help you develop your technical skills and engineering judgement.\nWe build primarily in Python, so experience with Python is valuable - but we’re equally interested in strong programming fundamentals and your ability to learn. If you’ve worked with Java, C#, C, C++, Scala, Go, Rust, or another modern programming language and are motivated to develop your Python skills, we’d like to hear from you.\nThis is a hands-on engineering role. You’ll write, test, review, and improve production software as part of an experienced engineering team. You’ll learn how well-designed software is built and operated in practice - from clean code and automated testing to APIs, databases, cloud services, observability, and production support.\nYou won’t be expected to know everything from day one. We’re looking for engineers with solid foundations, curiosity, and the willingness to learn, ask questions, take feedback, and gradually take ownership of increasingly complex work.\nIf you’re excited about developing as a software engineer while building systems used in global financial markets, we’d love to meet you.\nWHAT YOU’LL BE DOING\nWe’re building the next-generation index data platform at FTSE Russell - and you’ll help us build it:\nWriting clean, maintainable production code, primarily in Python, with guidance and support from more experienced engineers\nBuilding and enhancing software components, services, APIs, and shared libraries as part of a collaborative engineering team\nWriting automated tests and learning how to build software that is reliable, secure, and easy to maintain\nParticipating in code reviews - learning from feedback on your own code and gradually developing the skills to review the work of others\nInvestigating bugs and production issues, understanding root causes, and implementing well-tested fixes\nWorking with relational databases such as Aurora PostgreSQL, learning good practices around data modelling, queries, and schema evolution\nDeveloping software running on AWS using technologies such as Lambda, containerised services, object storage, and other managed AWS services\nContributing to data-intensive applications that process significant volumes of financial and index data\nUsing CI/CD pipelines and development tooling to build, test, and deploy software safely\nLearning how observability, logging, monitoring, and quality controls help us operate reliable production systems\nWorking closely with engineers, product colleagues, and other stakeholders to understand requirements and deliver useful solutions\nTaking part in design discussions and learning how experienced engineers evaluate technical options and trade-offs\nBuilding knowledge of financial indices and understanding how the software you develop supports our customers\nContinuously developing your engineering skills through hands-on work, feedback, pairing, and knowledge sharing\nWHAT YOU’LL BRING\nEssential - we’re looking for strong foundations and potential:\nA foundation in software development gained through professional experience, internships, graduate programmes, university projects, open-source contributions, or substantial personal projects\nProgramming experience in Python or another modern language such as Java, C#, C, C++, Scala, Go, or Rust, together with a willingness to develop strong Python skills\nUnderstanding of core software engineering concepts such as functions, classes, data structures, APIs, error handling, and automated testing\nAn interest in writing readable, maintainable code rather than simply making something work\nBasic understanding of software development practices such as version control, code review, testing, and debugging\nFamiliarity with Git or another source control system\nBasic knowledge of relational databases and SQL\nAn analytical approach to problem solving and the ability to break problems into smaller, manageable pieces\nCuriosity and willingness to learn new technologies, tools, and engineering practices\nOpenness to feedback and an interest in learning from more experienced engineers\nGood communication skills and the confidence to ask questions when something is unclear\nA collaborative mindset - you enjoy solving problems with others and contributing to a supportive engineering environment\nWe don’t expect Associate Engineers to arrive knowing our entire technology stack. Strong programming fundamentals, evidence that you enjoy building software, and the ability to learn are more important than having used every technology listed in this description.\nNICE TO HAVES\nBeneficial, but definitely not required:\nExperience building applications, APIs, services, or libraries in Python\nFamiliarity with Python development practices such as type hints, pytest, linters, and dependency management\nExposure to AWS or another public cloud platform\nExperience with PostgreSQL or another relational database\nUnderstanding of REST APIs and distributed or service-based architectures\nExperience with Docker or containerised applications\nFamiliarity with CI/CD tooling such as GitLab CI, Jenkins, or GitHub Actions\nExposure to infrastructure as code such as Terraform or AWS CDK\nExperience with data processing, ETL, or data-intensive applications\nExposure to Pandas, Apache Spark / PySpark, or similar data-processing technologies\nFamiliarity with object storage, data lakes, or technologies such as Apache Iceberg\nContributions to open-source projects or personal software projects you can talk us through\nExperience in financial markets, financial data, or investment analytics\nAn interest in financial markets and a willingness to learn the index domain\nJoin us and be part of a team that values innovation, quality, collaboration, and continuous improvement. This role is an opportunity to build strong software engineering foundations, learn from experienced engineers, and gradually take on greater technical responsibility while contributing to software used across global financial markets.\nWe're proud to have been recognised as a Great Place to Work® in India ‘25\nCareer Stage:\nAssociateLondon Stock Exchange Group (LSEG) Information:\nJoin us and be part of a team that values innovation, quality, and continuous improvement.
