Job description

So, who are we?

Hello, we're IG Group. We are a publicly-traded FTSE250 FinTech company who run mobile, web and desktop platforms that help our clients trade stocks & shares, leveraged products, Futures & Options and Crypto.


We are ambitious. Over 340,000 people already use our platforms. We're global with offices in 18 countries and products in 16 regions. We're hungry to move faster, ship better product for our customers and grow our user base. We believe in high autonomy, and we want people who are looking to do things differently in order to create better experiences for our customers.


We work in cross-functional teams and are laser focused on increasing the number of active clients we serve to drive sustainable growth.


Your role in the Team

The Direct Market Access (DMA/L2) system is responsible for connecting IG to Equity, Forex, Futures and ETP markets around the world and operate in a 24/5+ environment.


Our software is used by IG's dealing desks, client managers, trading services teams to help clients, hedge IG's risk and monitor our execution systems. We also make parts of it accessible to clients. We provide IG with access to multiple markets through multiple brokers, liquidity providers and venues and all are routed through the DMA and our Order Management System (OMS).


The new L2 Backend team will be working on decoupling backend and middleware services from DMA/L2 system to achieve new modern and robust target architecture.


What you’ll do

As a software engineer in the L2 Backend team, you'll take ownership of your work from elaboration to delivery. You'll take requirements and develop & extend solutions, test them and work with our stakeholders to deliver them.


This will include:

  • Interact with our senior developers and architects to analyse needs and requirements

  • Design and code solutions to meet these requirements

  • Deliver high-quality support and assurance as the work is rolled out

  • Ability to grow in the role and take ownership of projects end to end

  • Ability to learn and innovate!


Who we’re looking for?

You’re curious about things like the client experience, the rapid developments in tech, and the complex world of fintech regulation. You’re also a confident, creative thinker with a knack for innovating. We know that you know every problem has a solution. Here, you can try new ideas, and lead the way in creating inspiring experiences for our clients and everyone around you.


We don’t fit the corporate stereotype. If you want to work for a traditional, suit-and-tie corporate that just gives you a pay cheque at the end of the month, we might not be for you. But, if you have that IG Group energy and you can stand behind what we believe in, let’s raise the bar together.


What you’ll need for this role

  • Proven Java development experience

  • Strong knowledge of modern Java (JDK 17+), multithreading and concurrency, and Spring Framework

  • Experience with distributed caching solutions (Hazelcast or similar) is an advantage

  • Proficiency in design at system and component levels and able to take ownership of features

  • Good troubleshooting skills and able to eventually join the support rota

  • A good understanding of the Agile process

  • Excellent communication skills – the ability to communicate effectively with both technical and non-technical colleagues and stakeholders


How you’ll grow

When you join IG Group, we want you to have more than a job – we want you to have a career. And you can. If you spot an opportunity, we want you to chase it. Stretch yourself, challenge your self-beliefs and go for the things you dream of. With internal and external learning opportunities, and the tools to help you skyrocket to success, we’ll support you all the way.


And these opportunities truly are endless because we have some bold targets. We plan to expand our global presence, increase revenue growth, and ultimately deliver the world’s best trading experience. We’d love to have you along for the ride.


Where you’ll work

Ask our employees what their favorite thing is about working at IG, and you’ll hear an echo of ‘our culture’! That’s because you can come to work as your authentic self. The things that make you, you – like your ethnicity, sexual orientation, faith, age, gender identity/expression or physical capacity – can bring a fresh perspective or new skill to our business.


That’s why we welcome people from various walks of life; and anyone who wants to help us realize our vision and strategy.


So, if you’re keen to connect with our values, and lead the charge on innovation, you know what to do.
