Senior API Engineer - Remote

Company Description

PayNearMe develops technology to facilitate the end-to-end customer payment experience, making it easy for businesses to accept, disburse and manage payments. Our modern and reliable platform lowers the total cost of payments by increasing acceptance rates, driving self-service and simplifying exceptions. We future-proof our clients’ payments roadmap by including all payment types and channels through a single contract and integration. With PayNearMe, businesses can transform the outdated systems holding them back from achieving progress.

PayNearMe has over 200 employees, closed a $45M Series D round in June 2023, and is processing over $1B in payments monthly. We’re headquartered in Silicon Valley with our employees distributed all across the U.S. Help us solve our clients’ biggest payment problems.

We’re looking for a very skilled Ruby on Rails engineer to join a small but dynamic performance team, reporting to the CTO, in the role of Senior API Engineer. This position blends the analytical skills of a data analyst, the instincts of a high-performance coder, the imagination to come up with highly-performant designs, the drive to push your projects to completion, and the ability to work effectively with other teams. We love people who used to be the "go-to" person at their previous companies, but are now wanting to be part of a talented team.

Job Description

• You’ll be the primary owner of our APIs, helping us optimize and extend them
• For our existing APIs:
  • Build out performance tests for the high-usage calls (we use K6)
  • Use the results to tune these calls to be as efficient as possible (reader nodes, caching, etc)
  • Tune the default behavior for new clients to return minimal results
  • Ensure that our logging and monitoring is sufficient to detect potential problems (we use Datadog)
• Our APIs currently use an antiquated signature system, which requires much hand-holding
  • We have taken the first step towards OAuth 2.0 for one client (using Kong)
  • We want to make OAuth 2.0 available to all clients, running incoming requests through Kong
  • All of our APIs should run through this path so that Kong can do as much auth and validation as possible
• We use ReadMe to host our API documentation, with some well written documentation
  • Own the OpenAPI specification for our APIs
  • We need to point ReadMe at a separate and firewalled deployment and install an authentication system for clients to use
• With the experience gained above, start working on the next generation of APIs
  • How do we redesign them to be simple, modular and fast?
  • How do we design for 10x and beyond using horizontal scaling?

Qualifications

• Superb Ruby on Rails skills, with a minimum of 10 years of current Ruby on Rails experience
• Skilled at coding in Javascript, used in our performance test harness
• Experience and expertise building highly performant and high-throughput Ruby/Rails back-ends
• Experience with Go is a plus, but not required
• Experience building APIs, working with OpenAPI, and preferably Kong as well
• Familiarity with query optimization and web stack tuning (garbage collection, caching, throttling)
• Experience writing well instrumented code that can be monitored (we use Datadog)
• Understand the impacts of locking, network latency, batching, caching and I/O on software performance
• A proven track record in bringing clarity to ambiguous situations
• Ability to facilitate technical discussions, and to make challenging calls in a distributed team environment
• Familiarity with the AWS ecosystem
• Experience serving as a Tech-Lead
