We are seeking a Senior Python Backend Engineer to join our Digital Architecture Team (DAT). In this role, you will be the driving force behind the services that power our digital transformation, building the high-performance backend systems that turn raw engineering data into mission-critical capabilities. You will be responsible for designing and implementing scalable, secure, and maintainable microservices that sit at the heart of our autonomous mission management and data analytics platforms. You will work at the intersection of high-performance computing and cloud-native architecture, ensuring our backend is robust enough to handle the rigors of defense-industry requirements., Microservice Development: Design and develop high-performance backend services using Python, focusing on scalability, maintainability, and low-latency response times. API Design & Implementation: Lead the development of gRPC and RESTful APIs, utilizing Protobuf to ensure efficient, type-safe communication between distributed services. System Integration: Build the "glue" that connects our containerized microservices platform to both modern cloud databases and legacy Windows-based infrastructure. Backend Optimization: Optimize application performance through efficient concurrency models (AsyncIO), caching strategies, and database query optimization. DevOps & Deployment: Own the containerization of your services using Docker and Kubernetes, integrating them into robust CI/CD pipelines for automated deployment. Technical Leadership: Lead code reviews, establish Python coding standards (PEP 8), and mentor mid-level and junior engineers to ensure a high bar for software quality. ## Related Videos - [Exploring the Power of gRPC-Gateway for Writing RESTful Services](https://www.wearedevelopers.com/videos/2072-exploring-the-power-of-grpc-gateway-for-writing-restful-services) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [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) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Boosting OpenSearch Performance: gRPC Search in Action](https://www.wearedevelopers.com/videos/1964-boosting-opensearch-performance-grpc-search-in-action) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) ## Related Articles - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development)
