Our team of talented technologists, engineers, consultants, and subject-matter experts works alongside our federal customers to solve complex challenges, modernize critical systems, and make a meaningful impact on the missions we support. What makes Oasys different is the experience we strive to create for our employees. We offer the opportunity to do meaningful work while being part of a collaborative, people-focused organization where your ideas, expertise, and contributions are valued. We believe great people do their best work when they have opportunities to grow, are recognized for what they bring to the team, and have the flexibility and support needed to build a rewarding career.

Position Summary:

Oasys is searching for an experienced Full Stack Developer who will guide a development team in learning new tools and techniques, identifying and implementing system improvements, and mentoring teammates. The full-stack developer will design, build, and modernize secure, scalable, mission-critical applications hosted on AWS (Amazon Web Services), with responsibilities spanning application architecture, cloud infrastructure, and DevOps automation. The team uses Agile methodology and operates on 2-week sprints, tracked in Jira with documentation in Confluence. We use GitHub for our source code repository, and we automate our CI/CD pipelines there as well. The entire infrastructure is written and managed as code, and we promote cloud and open-source technologies. We are looking for a full-stack developer with experience in both monolithic and modern application architectures. Preferably, the candidate should have experience transitioning between monolithic and modern architectures, depending on what best fits the project. Our current suite of applications includes/combines Python, Django, Rails, React, TypeScript, Docker, Postgres, PostGIS, Snowflake, and more. If you are enthusiastic about being in a stack-agnostic environment and focusing on understanding the underlying core concepts and principles that drive modern application and infrastructure development, improvement, and maintenance, we would like to hear from you!

Contribute to decisions on service decomposition, API gateway usage, message queues, and distributed systems design.
Monitor and optimize application performance, scalability, and security across environments using tools like CloudWatch, Prometheus, Grafana, or similar.
Participate in and lead architecture reviews to evolve monoliths into microservices or hybrid models when appropriate.
All other duties as assigned by management.

Skills and Qualifications:

An ability to understand business requirements and their implications across a project’s technical landscape.
Ability to walk concepts forward and backward with the client and team – using your informed technical experience to negotiate/guide functional requirements from the front to the back end.

Required Education and Experience:

Bachelor's degree in Engineering, Computer Science, or another related analytical, scientific, or technical discipline; additional experience in lieu of a degree.
Minimum of five (5) years of demonstrated experience building and integrating complex full-stack applications using modern front-end frameworks, RESTful and GraphQL APIs, relational and NoSQL databases, and containerized backends.
Proven knowledge and practical application of HTML, JavaScript, CSS, or any other relevant web development experience.
Experience with modern JavaScript frameworks and libraries such as React, Redux, Vue, Ember, or Angular and knowledge of when to use them.
Experience with programming and software development, including analysis, design, development, implementation, testing, maintenance, quality assurance, troubleshooting, debugging, and/or upgrading software systems.
Experience implementing CI/CD pipelines with tools like GitHub Actions, GitLab CI, Jenkins, or similar.

Preferred Qualifications:

Experience with debugging front-end and back-end issues.
Experience with pair programming and Extreme Programming (XP).
Experience with any content management systems.
