Job description

Hi Folks,

We're Buyapowa and we're looking for 2 senior full stack developers (PE3+) to join us and help build out our core team.

Our primary Rails monolith is a referral marketing platform used by major enterprise clients. We pride ourselves on a lean but capable integration with high quality APIs and embedding that doesn’t lead to per client integration hell. We’ve recently released two new products: a client-facing ‘Campaign Management System’ and a Reward Distribution platform, as well as completing a rewrite of our referral tracking link processing system, which is now processing at 5k rpm with plenty of headroom.

Our stack is Rails with React front ends, backed by Postgres and Redis. We keep everything up to date on our projects and focus on maintainability.

We’re looking for candidates with good, up-to-date experience with:

• > 5 years of Ruby on Rails experience
• > 3 years JavaScript (ES6 and Typescript) experience
• > 3 years React experience including v18 and up
• Comfort with build pipelines, continuous integration, and Docker
• Proficiency with Git source control
• Strong HTML and CSS skills
• Good communication skills in written, verbal, and code
• Knowledge of Sidekiq, Tailwind, GraphQL, React Hook Form, React Query

We offer:

• An experienced and small team where you can have a great impact
• Freedom to experiment with tools and technologies to boost your productivity
• An opportunity to influence how we build high-quality software
• Collaboration with all levels of our enthusiastic product team, including design and UX

The process:

1. A quick chat with our recruitment team on Google Meet
2. Initial chat with our CTO on Google Meet
3. Technical interview with team members:
   1. No whiteboard technical test
   2. No take-home code exercise
   3. Discussion of previous design challenges
   4. Basic technical questions
4. Final interview and catch-up with CTO and other interested team members
