Job description

Senior Backend Engineer
Branding Brand is hiring a Senior Backend Engineer for a 12-week contract engagement (June 2026 to August 2026) to design and ship a new backend service to production for one of our clients. You will own delivery end-to-end of a reactive Java service built on Spring WebFlux, deployed on Kubernetes, with Redis for caching and Databricks as the long-term data store. The workload is bursty and high throughput, so the role requires solid instincts for idempotency, at-least-once delivery, and scaling under burst load.
This is a fully remote contract position. The candidate must be located in the United States and able to work as an independent contractor. No C2C.
Key Responsibilities:
Design and build:
  • Own the design and end-to-end implementation of a new backend service in Java 21 and Spring WebFlux
  • Build reactive, nonblocking HTTP endpoints that are racesafe and idempotent under retry
  • Make architecture decisions on caching, write paths, error handling, and scaling, and document the tradeoffs

Scale and operate:
  • Design the Redis caching layer for hot reads, idempotency de-dupe, and readthrough patterns
  • Design the async write path from the service to Databricks (queue or stream, batch writer, retry semantics)
  • Configure Kubernetes deployments, horizontal pod autoscaling, and graceful shutdown for safe deploys
  • Author K6 load tests for both steadystate and bursty traffic patterns
  • Wire up structured logging, metrics, and alerting for production critical paths

Support & maintain:
  • Troubleshoot issues across the API, caching, and datawrite layers in development and production
  • Participate in design reviews, code reviews, and Agile ceremonies
  • Provide production support through the contract period, including issue triage and resolution

Tech Stack:
  • Language and framework: Java 21, Spring WebFlux, Project Reactor
  • API Gateway: Apigee
  • Caching: Redis
  • Data store: Databricks (longterm, analytical), accessed via async batched writes
  • Messaging and async: SQS, Kafka, or Kinesis
  • Container platform: Kubernetes
  • Performance testing: K6
  • Cloud: AWS or Azure

Required Skills and Qualifications:
  • 6+ years of backend development experience
  • Hands-on experience with reactive programming and Project Reactor (Mono, Flux, non-blocking IO)
  • Production experience with Java and Spring WebFlux building RESTful or reactive microservices
  • Experience designing for idempotency, retries, and at least once delivery semantics
  • Comfort designing and operating services under bursty, high throughput workloads
  • Experience operating production services in a major public cloud such as Azure or AWS
  • Familiarity with data warehouse or lakehouse platforms (Databricks, Snowflake, BigQuery) as integration targets from an application service
  • Experience load testing services with K6, Gatling, Locust, JMeter, or equivalent
  • Commitment to secure coding practices and ongoing security awareness
  • Strong problem solving and communication skills

Qualifications:
Education:
Bachelor's degree in computer science, Information Systems, Business, or related
field
Preferred Attributes:
6+ years experience
