What is a Spring Boot Kotlin developer?

A Spring Boot Kotlin developer is a software engineer who specializes in building applications using the Spring Boot framework with the Kotlin programming language. Spring Boot is a popular Java-based framework for creating stand-alone, production-grade applications, while Kotlin is a modern language that runs on the Java Virtual Machine (JVM) and is known for its concise syntax and safety features. Developers in this role typically design, implement, and maintain backend services, APIs, and web applications, leveraging the benefits of both Spring Boot and Kotlin for efficient and scalable solutions.

What are the key skills and qualifications needed to thrive as a Spring Boot Kotlin developer?

To thrive as a Spring Boot Kotlin Developer, you need strong proficiency in Kotlin programming, a solid understanding of the Spring Boot framework, and experience with RESTful API development, often supported by a degree in computer science or related field. Familiarity with build tools like Gradle or Maven, version control systems such as Git, and knowledge of databases (SQL/NoSQL) are typically required, along with experience using CI/CD pipelines. Excellent problem-solving skills, effective communication, and the ability to collaborate in agile teams are valuable soft skills for this role. These competencies ensure efficient development of scalable, maintainable backend systems and effective teamwork in fast-paced software environments.

What are some common challenges faced by Spring Boot Kotlin developers when integrating with legacy systems?

Spring Boot Kotlin developers often encounter challenges when integrating modern microservices with legacy systems, such as dealing with incompatible data formats, outdated protocols, or limited documentation. These integrations may require additional effort for building adapters or converters, ensuring backward compatibility, and managing transaction consistency across distributed components. Collaborating closely with legacy system owners and leveraging Spring Boot’s extensive integration libraries can help overcome these obstacles and ensure smooth interoperability.

What is the difference between Spring Boot Kotlin vs Java Developer?

AspectSpring Boot KotlinJava Developer
Primary LanguageKotlinJava
Framework UsageSpring BootSpring Boot
CertificationsSpring & Kotlin certificationsSpring & Java certifications
Work EnvironmentBackend development, microservices, cloudBackend development, enterprise apps

Spring Boot Kotlin developers focus on building modern, concise backend applications using Kotlin with Spring Boot, often in cloud environments. Java Developers also work on backend systems with Spring Boot but primarily use Java. Both roles require similar certifications and are common in enterprise and startup settings. The main difference lies in the programming language preference, with Kotlin offering more concise syntax and modern features.

Job description

Job Title: Senior Kotlin/Spring Boot Engineer
Location: Salt Lake City, UT or Phoenix, AZ or Sunrise, FL
Worksite: Onsite
About WCT
WCT is a global talent solutions partner committed to delivering high-impact technology and engineering talent to some of the world's most innovative companies. As a WCT employee, you'll be part of a dynamic, growth-oriented culture that values collaboration, continuous learning, and excellence in execution.
Job Summary
  • We're hiring a senior Kotlin/Spring Boot contractor to help own the execution backbone of a no-code workflow platform. This is not a simple CRUD service. The Orchestrator runtime is a multi-module system that receives workflow execution requests, persists durable state with Temporal, coordinates graph execution, integrates HTTP, agent, LLM, and human-review nodes, and safely executes increasingly AI-generated workflow graphs. You'll join the squad responsible for the runtime layer that everything else depends on.

Responsibilities:
  • Design and harden the Kotlin/Spring Boot runtime that executes workflow graphs reliably in production.
  • Implement and improve Temporal.io workflows, activities, signals, queries, retries, and recovery paths.
  • Strengthen contract-first APIs and shared contracts.
  • Own failure-mode thinking across distributed execution retries, idempotency, partial failure, replay safety, pause/resume, and graceful degradation.
  • Work across node types, including HTTP, agentic tool-calling, LLM, and human-in-the-loop review nodes.
  • Improve integration coverage using Test containers and layered Docker Compose profiles.
  • Collaborate closely with Composer and AI/KB teams on execution semantics and runtime behavior.
  • Write clear operational documentation and runbooks for a reliability-critical service.

Qualifications:
  • Strong production Kotlin backend experience.
  • Strong Spring Boot experience in distributed systems or platform services.
  • Hands-on Temporal experience in production.
  • Strong understanding of workflow durability, retries, idempotency, and recovery design.
  • Experience with multi-module Gradle codebases and contract-first API design.
  • Experience with JPA/Hibernate and PostgreSQL.
  • Experience with Docker Compose/Test containers integration testing.
  • Comfort debugging multi-service systems with mixed Kotlin and Python components.
  • Experience with observability tools like micrometer
  • Experience with contract first development

Strong Pluses:
  • Experience with DAG/workflow/orchestration engines.
  • Experience with AI/LLM/agent runtimes or other non-deterministic execution systems.
  • Familiarity with FastAPI-based workers and cross-language integration.
  • Experience with auth/token provider abstractions, OAuth2/JWT, or cached token acquisition.
  • Experience writing operational docs, runbooks, and reliability guidance.

Compensation / Salary Range: The typical pay range for this role is: USD $110,000/Yearly - $125,000/Yearly. Factors that may affect pay within or outside of this range may include but not limited to geography/market, skills, education, experience, and other qualifications of the successful candidate.
Benefits: Medical, dental, Vision, Life, PTO, Holidays, 401(k) benefits and ancillaries may be available for eligible WCT employees and may vary depending on the nature of your employment.
WCT will accept applications and processes offers for these roles until the role is filled.
Equal Employment Opportunity Declaration:
WCT is an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to age, ancestry, color, family or medical care leave, gender identity or expression, genetic information, marital status, medical condition, national origin, physical or mental disability, political affiliation, protected veteran status, race, religion, sex (including pregnancy), sexual orientation, or any other characteristic protected by applicable laws, regulations and ordinances.
