Job Description
Senior Low Latency Java Developer
Contract Length: 12 months
AND Introduction
At AND, we accelerate the development of digital capabilities. In practice, that means helping ambitious leaders and organisations build the teams, products, processes and even operational structures they need to close the digital skills gap within their organisation today, so that they thrive tomorrow.
Clients rely on our experience, agility and craft skills across tech and business strategy, software development and product management to address some of the toughest challenges facing their businesses.
We bring aboard thinkers, tinkerers, passionate software craftspeople and inspiring technologists to help us solve these challenges. Together, we’re united by a sense of pragmatism, purpose and a deeply-held belief that digital products and technology alone won’t transform a business or save the world: it’s the people that count.
About you
As a Senior Low Latency Java Developer, you champion software quality and technical vision for AND and our clients. As a result, you will need to be able to:
- Work on large-scale, multiple industries, eCommerce and enterprise-level software development projects using languages and technologies such as Java, SpringBoot, Azure, Kafka, AWS and SQL.
- Experience with low latency systems
- Experience with high throughput scalable applications
- Knowledge of Hazelcast
- Knowledge of audio streaming/encoding and byte analysis techniques
- Champion software quality and technical vision for AND and our clients
- Champion TDD/BDD/XP Software development
To do that, it’s essential you bring the following:
- Hands on development expertise across the back end tech stack
- Problem solving skills and the ability to work as a team to make them a reality
- The ability to work in a collaborative environment where your ideas and opinions are valued and respected
- Experience working with Junior and Mid Developers in your team and assist with their mentoring and career development plans
- Be responsible for your own career development - with many different paths to choose at AND you will have the full support of the wider management team to progress your career at your own pace
Joining AND
From the work we deliver, to the way we serve and support our people, we work hard to ensure that there’s nowhere quite like AND. But joining a company is a two-way street: the fit has to work on both sides. So before you apply, here’s three key things to understand about us:
- We’re built for people - like, real humans. Not ‘resources’ or ‘staff’. That means happiness and wellbeing really do matter to us, and we hate unnecessary hierarchy and bureaucracy.
- There’s no well-trodden path ahead: AND is growing fast and forging a new trail. That’s exciting, and gives us all the autonomy and opportunity we love - but bear in mind it also demands focus, patience and resilience.
- Diversity is a priority. After all, to build great products that a wide variety of different people love to use, we need a wide variety of people to help us build them. So diversity is more than a policy or a word: it’s business critical for us.
Still sound good? Great! Fill out the short application form below and we’ll be in touch.
