You will design, build, monitor, and maintain backend services that power a complex, distributed, web-based software product. As a Senior Software Developer, you'll provide technical direction and work with the team to iteratively deliver production-grade microservices. You will help shape the technical direction and collaborate with team members to evolve our microservice architecture in a scalable Docker/Kubernetes environment that maintains a strong focus on reliability, security, and performance. What you'll do: * Design, develop, test, deploy, and maintain backend services and APIs for a microservice architecture. * Demonstrate the ability to implement modern architectural designs in software development. * Mentor the team in building resilient, observable, and secure services (e.g., health checks, structured logging, metrics, tracing, and alerting). * Implement data and integration patterns such as asynchronous messaging, event-driven workflows, and independent service-to-service communication. * Develop automated unit and integration tests to confirm the expected behavior of software during the build process. * Develop containerized workloads and deployment artifacts; contribute to Kubernetes deployments, configuration, and runtime troubleshooting. * Collaborate with Product, Design, other Engineering teams, and product stakeholders to translate requirements into technical solutions and deliver iteratively. * Improve developer velocity by contributing to CI/CD pipelines, automation, and engineering standards (testing, code review, documentation). * Mentor engineers and raise the quality bar through design reviews, technical guidance, and shared ownership of architecture decisions. * Actively participate in Scrum Agile events and provide your opinion and guidance as a technical professional during team discussions. * Responsibilities listed are not intended to be all-inclusive and may be modified as necessary. ## Related Videos - [Enterprise-Cloud-Native - Fast-Paced Development & Deployment in a Highly Secure Banking Environment](https://www.wearedevelopers.com/videos/671-enterprise-cloud-native-fast-paced-development-deployment-in-a-highly-secure-banking-environment) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Coding for Good: Achieving social change with an app](https://www.wearedevelopers.com/videos/1645-coding-for-good-achieving-social-change-with-an-app) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Top 10 Java Libraries](https://www.wearedevelopers.com/magazine/364-top-10-java-libraries) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know)
