Senior Python Engineer

Meet Slingshot

At Slingshot Aerospace, we're on a mission to make space safer and more secure for everyone. Our work directly impacts global security, disaster response, climate monitoring, and the critical infrastructure that connects our world. We're a team of builders, thinkers, and problem-solvers who believe that the next generation of space operations will be powered by better data and smarter software. We move fast, we're not afraid to fail, and we believe the best ideas can come from anywhere—whether you're in engineering, sales, product, or operations. If you want to work on something that truly matters, with people who care deeply about the impact we're making and help shape the future of an industry that's just getting started, you're in the right place. What You’ll Be Launching

Hiring for two Senior Python Engineers to help architect and build secure, scalable, high-performance data processing and intelligent application platforms in the Washington DC–Baltimore area. Work is mostly done remotely but regular site visits in the DC area are required. Requires deep expertise in Python, FastAPI, distributed event-driven systems, MongoDB, and in-memory data technologies such as Redis. The engineer will play a key role in system architecture, development of production-grade services and pipelines, and implementation of best practices across data ingestion, transformation, streaming, AI integration, and secure software delivery. Experience with Retrieval-Augmented Generation (RAG) systems and Agentic AI workflows is highly desirable. This team is actively re-platforming a mission-critical production data pipeline from a legacy first-generation architecture into a modern, cloud-native, event-driven platform. These are newly created positions—not backfills—established specifically to expand the engineering team responsible for designing and building the next-generation system alongside an experienced group of senior engineers and architects. This is a highly hands-on engineering role within a small, senior-level team focused on re-architecting a high-throughput, mission-critical data platform. Engineers will work across several high-impact initiatives, including replacing tightly coupled synchronous processing patterns with asynchronous, event-driven microservices and defining the service boundaries, repository structure, and engineering standards that will support the platform long term. This is a true greenfield modernization effort. Candidates joining at this stage will have direct influence over architecture decisions, service ownership, development standards, and platform strategy. The environment combines modern cloud-native technologies with a serious compliance and security posture, including AWS GovCloud, FastAPI-based Python services, managed AWS infrastructure, Kubernetes with KEDA autoscaling, and Datadog observability. Engineers looking to work at the intersection of advanced distributed systems, cloud-native engineering, and government-grade security will find a strong fit in this opportunity.
