How much do spring webflux jobs pay per hour?

As of Jun 4, 2026, the average hourly pay for spring webflux in the United States is $59.29, according to ZipRecruiter salary data. Most workers in this role earn between $54.81 and $64.66 per hour, depending on experience, location, and employer.

What are the key skills and qualifications needed to thrive as a Spring Webflux Developer, and why are they important?

To thrive as a Spring Webflux Developer, you need strong proficiency in Java, reactive programming, and a solid understanding of the Spring Framework, particularly Spring Webflux. Familiarity with tools like Reactor, Maven or Gradle, RESTful APIs, and experience with version control systems such as Git are commonly required. Effective problem-solving, communication, and adaptability are standout soft skills for collaborating on complex, scalable web applications. These skills and qualities are crucial for building high-performance, non-blocking applications that meet modern enterprise requirements.

How does a Spring Webflux developer typically collaborate with front-end teams during project development?

Spring Webflux developers often work closely with front-end teams to design and implement reactive APIs that support efficient, asynchronous data exchange. Regular communication is essential to ensure that endpoints meet the performance and data requirements of modern single-page applications or mobile clients. Collaboration usually involves joint planning sessions, shared documentation, and iterative testing to quickly resolve integration issues, ensuring seamless user experiences across the stack.

What is Spring WebFlux?

Spring WebFlux is a reactive web framework introduced by the Spring team as part of Spring 5. It allows developers to build scalable, non-blocking, event-driven web applications using reactive programming principles. Unlike the traditional Spring MVC framework, which is servlet-based and synchronous, WebFlux is designed to handle a large number of concurrent connections efficiently using asynchronous processing. It supports both annotation-based and functional programming models, and can run on servers like Netty, Undertow, or traditional servlet containers. This makes it ideal for applications that require high concurrency and low latency.

What is the difference between Spring Webflux vs Spring Boot Developer?

AspectSpring WebfluxSpring Boot Developer
Primary FocusReactive, non-blocking web applicationsBuilding and configuring Spring Boot applications
Required SkillsReactive programming, WebFlux framework, JavaSpring Boot, Java, REST APIs
Work EnvironmentDeveloping scalable, asynchronous servicesFull-stack or backend development using Spring Boot
Industry UsageModern, high-performance web servicesGeneral enterprise application development

Spring Webflux specializes in reactive, non-blocking web applications, while Spring Boot Developers focus on creating and configuring Spring Boot-based solutions. Webflux emphasizes asynchronous processing, whereas Spring Boot developers work across various Spring projects. Both roles often overlap but serve different core purposes within the Spring ecosystem.

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
