Job Description:

We're looking for a Associate Technical specialist to help build and scale a production REST API. Our stack currently leans toward Ruby/Rails, but we're framework-agnostic when it comes to experience — strong backgrounds in Django, Laravel, NestJS, or Spring are all welcome. What matters most is deep, senior-level expertise building and operating ORM-backed REST APIs in production.

Background job processing — hands-on experience with Sidekiq, SQS, Celery, Bull, or equivalent, including designing for idempotency and safe retries

Automated API testing — proficiency with RSpec, pytest, JUnit, or equivalent testing frameworks

Authentication & authorization — practical experience with token-based and OAuth flows

Search infrastructure — experience with OpenSearch or Elasticsearch, including query DSL, nested queries, and reindexing strategies

External system integrations — experience integrating with an external system of record; Salesforce experience strongly preferred

Willingness to work in Ruby/Rails — no prior Rails experience required, but candidates must be open to learning and working in it day-to-day

Nice to Have:

Rails / Ruby experience

Salesforce sync experience (SOQL, object mapping, polling, push-on-change patterns)

PeopleSoft, SOAP, or other ERP integration experience

AWS services (S3, SQS, RDS)

Docker Compose

Feature flag systems and progressive rollout practices
