Server-side Software Developer

Location: London or Poznan or Remote (within Europe or Asia)

We're looking for creative server-side software developers

Join our back-end teams building user-friendly online services for consumers. We use a micro-services architecture with a broad range of different technology stacks and high levels of automated test coverage. The majority of our back-end is written in Ruby.

Highlights

• Scale and performance challenges. Handle tens of thousands of rpm, scale across geographically distributed datacenters, solve complex computational tasks quickly, and be highly available.
• Security. We work with world-class penetration testers.
• API design. We have client-side apps for Windows, Mac, Android, iOS, Linux, routers, and browser extensions for Chrome, Firefox, and Safari. Keep the API designs simple and meet the various requirements for our apps.
• Split-testing. We make heavy use of A/B testing to optimize our front-end for sales conversions. We have enough volume to often get significant results within one day.

Responsibilities

• Your responsibilities may cover systems that each bring their own set of interesting technical and design challenges, especially around scale, security, and availability.

• Continuous Delivery. All logic is tested automatically. We deploy multiple times per day. We often use TDD.

• Microservices architecture. We can pick the right stack for each individual application. Currently those involve combinations of Ruby, Go, Node.JS, C, mySQL, Postgres, Redis, MongoDB, RabbitMQ, Docker, Chef and Ansible.

• Code-reviews. We invest in spreading knowledge around the team, and keeping our code easy to read, test, and maintain.

Requirements

• You love to solve problems, you’re excited about building well-designed systems, eager to learn and continually improve your skills.
• You take great pride in the quality of your code
• Expert in at least one modern server-side language. You test your code primarily with automation.
• Eager to learn some Ruby (you’ll see a lot of it here, though it won’t necessarily be your primary language)

Optional

• Nice to have: Experience building high-load scalable systems
• Nice to have: Devops experience (Linux, Docker, Nginx, Ansible, Kubernetes, Terraform, Cloud-based Databases, Queues)
• In general, we’re looking for someone with raw smarts and potential who can easily learn the specific skills needed for our work.
• We’re open to candidates with various levels of experience. From junior to very senior, come talk to us!

What we offer

• Challenging work in a fun and collaborative environment
• Attractive compensation and time-off benefits
• Spacious open-concept and centrally located offices
• Full-time employment with flexible working hours
• Fully stocked pantry with fresh fruit and snacks
• Team lunches and company events every quarter
• Multicultural teams represented by 30+ nationalities
