You’ll get the opportunity to utilise a variety of technologies to pave the future of Bark whilst enhancing how we solve complex online problems in cutting-edge areas such as search, classification and core marketplace services.

- Proactively propose and implement improvements to the codebase.
- Design and code solutions for systems with 1000s of transactions a second.

Required skills and experience:
- Using Python in a production environment.
- Defining, implementing and testing APIs.
- Understand SOLID principles.
- Integrating with 3rd party APIs, including OAuth flows and similar.

- Knowledge of Apache Airflow, Spark, Hadoop and other data toolkits.
- Experience with other data stores like Elastic, MongoDB or similar.
- Interest in machine learning topics such as logistic regression, nlp and others.
- PHP experience with a framework (Laravel, Symfony, Zend, CakePHP etc) would be a bonus, but not essential.
What our devs say...Henry, Tech Team Lead - “It’s an exciting time to join Bark in many ways but especially from a tech point of view, because we’re at the beginning of the biggest architectural transition in the company's history. As we transition from a startup to a much larger company, we need to upgrade our stack from a few monolith systems, to much more scalable, maintainable, decoupled services.”
George, Developer - “Working so closely with the product and design teams gives me an opportunity to get involved in the product from the earliest stage. Each week we build a new experiment which is a true collaboration of the ideas from everyone in the group. Due to the scale of Bark as a business, it’s also hugely rewarding to see that the work we produce can make a massive impact, by generating millions of pounds in annualised revenue.”
Tom, Senior Product Designer - “There's a real sense of camaraderie across the company. The tech side of the business is really exciting at the moment – we broke into different teams and the effect is phenomenal. Never a dull moment, and feels like we're making real measurable change to the product for our users!”
