The platform enables planners to explore complex healthcare-system scenarios through data integration, simulation, and interactive analysis. This is a hands-on software engineering position for someone who enjoys working across the full software development lifecycle. The Software Engineer will design backend services, build data and simulation pipelines, contribute to cloud architecture, and carry features from initial requirements through deployment and demonstration. The application includes a web-based user experience, but the role's current emphasis is backend engineering, cloud infrastructure, data processing, and complex systems design., * Own software features from initial design through implementation, testing, deployment, and ongoing improvement. * Design and build Python services, APIs, data-processing workflows, and simulation capabilities. * Develop modeling logic in collaboration with subject-matter experts and integrate that logic into a production application. * Build and maintain cloud-native workflows using AWS services such as Lambda, Step Functions, SQS, and S3. * Work with different compute and deployment models based on performance, scalability, and security needs. * Design and maintain data pipelines that ingest, validate, transform, enrich, and publish source data. * Develop APIs and backend application functionality using Python and FastAPI. * Work with PostgreSQL, SQLAlchemy, and Alembic to design schemas and manage database changes. * Contribute to a Next.js frontend when needed, while primarily focusing on backend and platform development. * Build and maintain automated delivery workflows using GitLab CI/CD and GitHub Actions. * Package and deploy applications using Docker. * Apply DevSecOps practices such as automated testing, code review, dependency management, security scanning, observability, and infrastructure as code. * Participate in architectural and technical design decisions. * Demonstrate completed capabilities to users and incorporate their feedback into future development. * Diagnose challenging technical problems across application code, data, infrastructure, and deployment environments. *This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth. ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
