What is the role? E-Space is looking for a Senior Software Engineer to join our Ground Software team. You will collaborate with multidisciplinary engineering teams to build the mission-critical software that powers our satellite constellation operations. You will develop highly available, highly-scalable backend systems using Python in an API-first, event-driven architecture deployed in the cloud using containerized solutions. Working on greenfield projects, you'll be responsible for the entire software development lifecycle—from system design and architecture to hands-on coding and infrastructure implementation. This role combines technical leadership with deep engineering work, making foundational decisions that will scale with our growing constellation.
What you will be doing:
- Architect and scale a Python-based Ground Data System designing microservices that handle real-time command uplink, telemetry downlink, and event processing across a growing constellation
- Build binary protocol pipelines for CCSDS-compliant spacecraft communication, including TC/TM framing, CFDP file transfers, and AES encryption/decryption
- Own the messaging infrastructure to evaluate and optimize MQTT broker architecture, and quantify performance bottlenecks (MQTT throughput, QoS tuning, database writes, CPU-bound encoding/decoding)
- Build high-performance APIs for mission-critical command and control operations
- Create workflow orchestration systems for automated satellite and ground procedures
- Integrate with ground station networks and cloud infrastructure to develop scalable data ingestion and processing pipelines for high-rate satellite telemetry and command streams
- Establish software engineering and DevOps best practices including code reviews, testing standards, and architectural guidelines
- Collaborate cross-functionally with Flight Software, Payload, and Mission Operations Teams
What you bring to the role:
- 5+ years of backend software engineering experience building scalable, fault-tolerant systems for telemetry ingestion, command & control, or real-time data processing at scale
- Proficiency with microservices architecture, message queues, gRPC, and protobufs
- Expert Python skills with experience with modern frameworks (FastAPI, Pydantic, SQLAlchemy), asynchronous programming (asyncio, threading), API development
- Knowledge of CCSDS protocols (TC, TM, CFDP) or willingness to learn space communication standards quickly
- Time-series databases (InfluxDB, TimescaleDB, or similar at high ingest rates)
- Kubernetes production experience (HPA, resource management, networking, debugging pods at scale) Experience designing and implementing event-driven architectures and workflow orchestration systems
- Solid understanding of AWS services, PostgreSQL, and container-based deployment solutions
- Hands-on experience with CI/CD pipelines, automated testing, and modern software development practices
- Experience with message bus systems (Kafka, MQTT) and in-memory databases for real-time data processing
- Knowledge of Infrastructure as Code (Terraform/OpenTofu), monitoring/observability tools, and high-availability system design
- Experience with high-throughput data processing and performance optimization for mission-critical applications
- Strong system design skills with ability to make architectural decisions for scalable distributed systems
Bonus Points for the following:
- Bachelor's degree in Software Engineering, Computer Science, or equivalent
- Experience with Kubernetes and container orchestration platforms
- Knowledge of time-series databases
- Background in satellite operations, mission control systems, aerospace, defense, or other mission-critical industries
- Grafana/observability stack for distributed systems monitoring Strong intellectual curiosity and commitment to continuous learning
- Exceptional attention to detail and an ownership mentality
Additional Requirements
- This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
