Job description

We have officially expanded into the UK, and we are looking to hire engineers to join the team. We’re really lucky to have an Engineering team spread across three jurisdictions working on the Hnry product. While that gives us the opportunity to hire great people globally, we’re looking for a Platform Engineer to join our founding London team.

You will play a key role in the team that takes ownership of the infrastructure, performance, and security of the Hnry platform. Our Platform Squad is responsible for keeping our AWS servers and databases running smoothly, and making sure we’re set up to scale with confidence.

Design, build and maintain improvements to the infrastructure and platform of Hnry, currently hosted on AWS

Improve the reliability, availability and performance of our platform

Evolve and optimise our CI/CD pipelines to enable fast, safe and consistent deployments

Implement and enhance observability (monitoring, alerting, logging) using tools like DataDog to ensure high-availability APM

Apply best practices in security, scalability and cost optimisation across our infrastructure

Support incident response and proactively identify and resolve system issues

Produce work that meets the expected level of test coverage and improve test coverage across the existing codebase

Share knowledge and contribute to engineering standards and ways of working

Have a pragmatic approach to improving system reliability, performance and scalability

Actively monitor systems, identify problems and propose solutions

Bonus points for the following:

• Experience optimising PostgreSQL databases
• Experience with Ruby on Rails or supporting Rails-based applications
• Experience working on systems at scale
• Experience in a startup, scale-up, or high-growth environment
• Experience being self-employed (freelancing, contracting etc.)

How we work

We follow agile practices, delivering improvements iteratively in small chunks. We track the impact of our work and measure ourselves on results, not the amount of code written.

We’re growing fast, and are focused on building a well designed, scalable & robust platform. In some areas of the work (e.g. payment processing) there is very little margin for error.

Our technology platform is built in Ruby on Rails, hosted on AWS services (via Terraform), Postgres, Docker

We have wide automated test coverage, continuous deployment via CircleCI, and our Engineering team release to production multiple times per day.

We review each others code, and set aside time for hacking on experimental features, refactoring and/or learning new things.

We work hard and finish on time, no crazy hours.

Salary banding: £60,000 - £70,000 per annum

At Hnry, we operate a policy of pay parity across our organisation to ensure that all Hnry staff are fairly and equally compensated based on their contributions and experience. The salary for this role will be determined based on the applicant’s experience.
