We are looking for 1 or 2 additional developers to join our team to help us deliver features to our growing list of customers. You will be joining a team of smart and motivated engineers, working on both the client app and the back-end services. We have a modern, cloud-based architecture, and there will be challenges and learning aplenty.
Annual salary of up to £60k
28 days annual leave + your birthday off
Flexible working as standard
Personal development budget
Fun office in the heart of Soho and regular social events
Yapster’s mission is to empower people working in roles traditionally underserved by productivity-boosting enterprise software. We’re already working with some of the best names around - think Ann Summers, Caffe Nero, Krispy Kreme, and Next - to do just that.
After closing a significant round of private investment at the end of last year, we’re gearing up for rapid growth through 2019 and beyond. With your help, our mobile messaging platform will be used and loved by millions of frontline workers across the world in the coming years.
Based in the heart of Soho, we’re a friendly, fun team united by a passion for building a first class product and company culture. You can expect to work alongside brilliant people and join a fast-paced culture where everyone relishes getting ‘stuck in’.
The dev team
Yapster’s dev team is currently 6 engineers (including the CTO). We are self-motivated, enthusiastic and bring a wealth of different experience - we are welcoming of new viewpoints and the increased problem-solving capability they bring to our development process. We are currently quite un-siloed and each of us can, and do, work on any part of the Yapster application (front-end, back-end, Android, iOS, web). We are working mostly remotely (this has clear advantages for optimising flow and minimising interruptions), with a weekly office-day in London - but we’re flexible, and if you want to work more from our office that is a possibility, or if you are further afield (within the UK and Éire) then fully remote is also a possibility.
Major Responsibilities / Accountabilities
Yapster platform development: Mostly Clojure and ClojureScript, developing features on the Yapster app and backend, bugfixing etc.
Integration & connector development: Yapster provides various integration points, and you will be extending these, and specifying and developing new connectors
The Yapster app is available on iOS, Android and browser platforms, and is written in ClojureScript with Reagent and re-frame. We use Apache Cordova to deploy a native app to iOS and Android.
The back-end has a REST API implemented in asynchronous Clojure with Yada, there are stream and batch processing components built on Kafka+Kafka Streams. We use Apache Cassandra for persistence and Apache Kafka for persistent messaging and gnatsd to feed our WebSockets. The back-end is deployed to Kubernetes on AWS.
Required skills and experience - technical
Clojure || ClojureScript (both is a bonus!)
Good understanding of functional programming paradigm
Familiarity with web apps, HTML and CSS (but not visual design)
Happy to pull apart other people’s code to find out why something isn’t working as expected - unstoppability
Required skills and experience - personal
Good written and oral communications skills
Able to work with little direct supervision (though there will be plenty of supervision available, it won’t always be co-located)
Able to work effectively in a team environment where team members may not be co-located
Self motivated and proactive
Excellent problem-solving skills
Interested in better ways of doing things, yet remaining aware of the realities of delivering features to customers
Flexible approach to day to day tasks and coping with a challenging workload
Desirable skills and experience - but can be learned on the job
Asynchronous programming techniques
Data modelling and operational experience with Apache Cassandra
A demonstrable understanding of computer architecture and operation - whether acquired through formal education or otherwise isn’t so important.
We aspire to build a team that properly reflects the communities we serve and welcome applications from people with diverse perspectives and backgrounds.
