Job description

At Longshot Systems we build advanced platforms for sports betting analytics and trading.

We're hiring for a Junior Software Engineer within our trading platform team. The primary function of this team is to manage our in-house trading platform which integrates with sports betting trading venues globally. You’ll be working on these integrations and on the core platform alongside an experienced team doing creative, challenging work.

Our tech stack is distributed and event driven, written in golang on top of postgres with many integrations to betting exchanges and bookies via APIs and via web scraping.

You'll also be working closely with the wider company including sports modelling researchers, trading analysts and the commercial team. You will focus on helping maintain trading infrastructure and helping the team scale and improve the systems at the heart of the business.

The ideal candidate will be highly creative and enjoy generating new, innovative ways to tackle problems and suggesting improvements to existing methodologies. Knowledge of sports betting is not required. Knowledge of web technologies up and down the stack is vital.

We are a hybrid working company. We come in every Thursday to our London (Farringdon) office and work remotely the rest of the week. Our typical working hours are 10 am to 6 pm UK time, Monday to Friday, but we support flexible working and trust our team to manage their own schedules to meet their goals.

For this role, we’re targeting early-career developers with a bias toward academic excellence and either relevant industry experience or demonstrated capability to use and learn a wide array of tools and technologies.

The recruitment process is:

1. A brief screening call to give you some more information about the role, answer any of your initial questions and to check your suitability for the role.
2. A 90 minute technical interview discussing your previous experience, technical knowledge and to answer any questions you may have about the role. We’ll also do a bit of pair programming in your systems language of choice.
3. A collaborative coding assessment day, working with one of our team on some sample problems. This isn't leetcode, it’s more general and will allow you to show us what you can do in the areas you excel at. This will last from 10am until 4:30pm UK time either in our office in London or remotely.
4. If you did the full day assessment remotely, then a "meet the team" at our London office for lunch or dinner and some face to face time with the team and management.

You must have a degree in a scientific or technical subject from a top global university demonstrating your ability to grasp and apply complex concepts. It doesn’t have to be computer science, but you do need to be a proficient coder with a passion for the work. While we are happy to provide extensive training, we do need a certain baseline ability in software engineering and computing to work from. The ideal candidate is someone who loves a challenge and is ready to get involved.

Must-haves

• Solid Computer Science fundamentals (data structures, concurrency, networking).
• Proficiency in at least one systems language — Golang, Rust, Java, C++, or C#.
• Excellent written & spoken English for remote collaboration.
• Permission to live and work full time in the UK. We do not offer visa sponsorships for this role.

Nice-to-haves

• Production work with Golang or AWS.
• Scripting / web tech (Python, JavaScript/TypeScript).
• Web-scraping experience.
• 0–2 years professional software experience or equivalent projects.

Our salary range for the role is £35,000 to £50,000, depending on experience and interview performance.

List of benefits:

• Participation in the uncapped company bonus scheme
• 10% matched pension contributions
• Private healthcare insurance
• Long term illness insurance
• Gym membership
