Arachnys’ core competency is harvesting data from the wild and helping customers use it to support better business decisions – about who to take on as a customer, which suppliers to use and who to hire. Arachnys allows customers to search 23,000 corporate, news, social media and litigation sources – spread over 220 countries – in more than 90 languages.

Our approach is nimble and responsive, with close integration between marketing, sales and tech.

Office location

Our offices are located five minutes’ walk from Bank. It’s a bright, airy space equipped with free food, showers, an awesome coffee machine and fresh towels, standing desks, and great people. We have beautiful floor to ceiling views over the Thames.

Visas and sponsorship

We are able to offer to sponsor visas and pay relocation expenses only for exceptional candidates. Please contact us if you have any questions.

Remote working may be suitable for some roles, but we have a strong preference for teammates based in London (or commuting distance). If you’re unsure, please get in touch and ask.

Closing dates

All roles are advertised with the potential to start immediately unless stated otherwise. If the role is still advertised, it’s worth applying.

How to apply

  • Email to introduce yourself and tell us how you think you fit the role
  • Make your subject line the same as the job title you are applying for

Please follow these guidelines:

  • Write your covering letter in the body of your email, not as an attached Word or PDF document
  • For technical applicants, please include a link to your GitHub profile or similar. If you’re proud of your GitHub, we probably won’t need to see a formal CV until further on in the recruitment process. If in doubt, please ask.
  • Please attach an up-to date CV

We aim to respond to all applications within ten days; please check your spam folder if you do not receive a response from an application. We will not acknowledge receipt of individual applications.

We do not currently work with recruiters or consultants, but we will answer legitimate enquiries from individual candidates.

Speculative applications

If you’re excited by what we’re doing and think you could be a good fit for the team, don’t worry if you don’t see a job spec which perfectly matches your skills. Feel free to send your CV marked for the attention of the founders.

In particular, we’re always on the lookout for the exceptional technical candidates. We read and respond to every bona-fide application.


On the tech side, we work on hard but rewarding problems with advanced, performant technologies. We run our own distributed infrastructure with physical and virtualised servers located all over the globe, including a 100TB+ Hadoop cluster and a 10TB+ ElasticSearch cluster. We use Ansible for configuration and deployment.

Our main customer-facing application is a Django application, with the front-end code written in CoffeeScript using Backbone.js, LESS and other modern, open-source frameworks and tools. We also use assorted other open-source technologies such as Golang, Vagrant, PhantomJS, Postgresql, Redis, gevent, Celery and Scalding.

Sitting behind the customer-facing app is a 100TB+ data cluster powered by Hadoop/HBase, ElasticSearch, PhantomJS and other fun technologies.

We are contributors to open source, with our Cabot server monitoring tool starred over 2,000 times on GitHub and AthenaPDF, a PDF generation project in Go, over 1,000 times. We are constantly looking for opportunities to open-source more and more of our non-core tech.
