Senior Software Engineer (C++)
Come work on fantastically high-scale systems with us! Blis is an award-winning, global leader and technology innovator in big data analytics and advertising. We help brands such as McDonald's, Samsung, and Mercedes Benz to understand and effectively reach their best audiences. In doing this, we are industry champions in our commitment to the ethical use of data and believe people should have control over their data and privacy. With offices across four continents and over 270 people on the team, we are a truly international company with a global culture and scale. We’re headquartered in the UK, financially successful and stable, and looking forward to continued growth. We’d love it if you could join us on the journey!
We are looking for brilliant, creative, curious, and experienced C++ software engineers to join our real-time applications team. This team is responsible for our high-throughput, low-latency trading and measurement systems that routinely handle hundreds of thousands of requests per second, leveraging multi-level machine learning models covering classification and optimisation, all with a 98th percentile latency of under 20ms. These systems both create and use massive data volumes to make intelligent trades on dozens of global marketplaces. They also help with a range of other offline and online projects, from our proprietary algorithms and systems for location data processing to integrations with third-party technologies. As a tech-first product company, this team works on things that are visible and matter to customers and the business!
Software engineers at Blis are more than just programmers - they’re people who are builders, designers, and problem solvers at heart, people with a passion to make things better. You will help innovate and design new features and products, work with the team to build them, and support and grow them after they’re live. We discuss ‘why’ as much as ‘what’ and ‘how’ in our planning meetings because we want you to see and help shape our future. We value soft boundaries between teams and you’ll get to work with other engineers, data scientists, and product managers to see how it all comes together. As engineers, you’ll help us follow good design principles, especially those inspired by Lean Development, and you’ll enjoy learning, growing, and pushing yourself and the products in new ways. And, of course, you’ll enjoy being part of a team that supports each other through mentoring, brainstorming, and pairing up to solve ambitious challenges.
This role can be offered on a hybrid basis for candidates that have full time residency in the UK. Our ask if that you could join in-person meetings in either our London office in the Shard or our Engineering hub in Edinburgh. Tthese are infrequent (averaging once a quarter or less).
