About this role:

Our team is growing because our user base is growing (30% in the last year!) which means we need you! We’re looking for a strong Backend Engineer who is passionate about building, testing, deploying, and working closely with the Product team to deliver new features. You will have the opportunity to solve challenging problems, work with the latest systems, collaborate with a kind and capable team, and contribute meaningfully.

This position is located in Medellin, Colombia, and requires working onsite Tuesdays & Thursdays at the Grindr offices at Tinkko Coworking Office Milla de Oro, Medellín. Open to candidates willing to relocate within Colombia.

What you'll do:

•Be a part of the engineering team where we implement new features and work closely with the product and design teams

•Build for the future by designing maintainable and well-tested systems to serve a global audience of millions of concurrent users (we’re big!)

•Own the design and development of Grindr’s backend services in a stable and scalable microservices architecture

•Work with Product Managers, Designers, and other Engineers to refine feature design and functionality

•Build for the future by designing and testing simple, elegant, maintainable software

•Optimize key pieces of Grindr's platform using tools like Redis, Postgres, and Kafka on AWS services

•Innovate by guiding data-driven decisions to adopt new technologies, architectures, and workflow

•Ensure high availability of the Grindr platform through distributed systems and infrastructure engineering

•Help guide and mentor team members through pairing sessions, code reviews, and architecture reviews.

•Troubleshoot unexpected issues across various systems because being the most popular is hard… and fun :)

•Take a prominent role in optimizations, cost savings, and incident responses.

What you'll bring:

• 8+ years of experience as a Software Engineer developing critical portions of working on Backend Systems (Service APIs, Data Processing, Messaging Services)

• Experience designing and implementing large-scale Web or API systems for high load and data consistency

• Experience with Kotlin or at least one JVM language is required.

• Experience designing and productionizing large-scale distributed systems

• Deep understanding of concurrency concepts and trade-offs

• You love figuring things out and understanding how they work end-to-end

• Experience with continuous integration and continuous delivery

• Experience with SQL and general knowledge of database systems

Nice to Haves:

• Experience of mentoring / skilling up less experienced developers.

• Experience developing or working with Continuous Integration and Continuous Delivery tools, such as Github Actions or CircleCI.

• Experience designing systems that make heavy and efficient use of Cloud Services (any cloud)
