Percentile | London, UK | Full time | Onsite

Percentile are a young technology company building high performance risk management software for the financial world. We're looking for a junior developer to join our small but growing team in the Bank/Monument area of London. The successful candidate would be responsible for enhancing existing features, adding new ones (including greenfield work), along with some support and QA. Don't worry, we won't expect you to know everything up front, but we will expect you to be bright, enthusiastic and willing to learn. As you grow into the role you will gain solid experience in a range of technologies including Java, Javascript, React, Kotlin, HTML, C#, SQL Server, Oracle, OLAP, distributed systems, AWS, and a variety of well regarded tools and libraries.

While a 1st in Computer Science and experience with some of Java/Javascript/Kotlin/HTML/SQL is preferred, we realise there's a wealth of talented developers out there who don't fit that mould - so if you're passionate about software and have some good experience under your belt or have made some interesting contributions to open source projects you'd love to share with us, we'd still be keen to hear from you. In return we can offer a flexible and very technology focused environment working alongside experienced developers, a relaxed dress code, plus solid exposure to the world of investment banking and capital markets.

That's about it really! If this sounds interesting, we look forward to hearing from you at careers@percentile.co.uk

* You are a full-stack engineer who wants to work everywhere, not just a small subset of components. Experience / interest in working in a variety of layers and technologies within a SOA is a must for our team. This includes: client-side AngularJS / JQuery, MVC-based web architecture, external RESTful APIs, distributed (and in our case, highly scaled) request handling services, no-SQL and relational SQL databases, many-layered data pipeline (e.g. data bus architecture, Hadoop / MPP data warehouse, etc.) that moves hundreds of thousands of items per second, and data visualization (e.g. Tableau). Experience in all these layers is not strictly required, but we do like to see experience working in more than one, as well as eagerness to work on projects that might slice through them all.

* You have product-driven software development experience using a modern, object-oriented language. Memory-managed languages are best -- .e.g. C#, Java, Python, Ruby, etc. We do most of our work in C#/.Net, but specific experience here is not required.

Cool stuff about TTD:

* Our platform processes 5million+ queries per second

* Work with the best engineering team in AdTech

* The combination of huge data sets, high throughput, low latency and amazing scale means that we're constantly solving some of the biggest challenges in computer science.

* We've grown faster than any other adtech company in the industry, and have been recently recognized as one of the fastest growing companies in America by Inc. Magazine and Deloitte.

* Amazing Company Culture (We're very proud of our top rating on Glassdoor)

* Top-tier benefits

If you're interested, please apply directly on our website: https://www.thetradedesk.com/join-us/open-positions

*Note: We are also hiring a Big Data DBA (Vertica), an East & West Coast Solutions Architect, a Sr. Data Scientist, and a BI Data Warehouse Developer!
