System Architecture and Design

• This area measures your ability to design robust, scalable, and fault-tolerant distributed systems from scratch. Astra relies on resilient infrastructure, making your architectural foresight critical.
• Strong performance requires identifying bottlenecks, choosing appropriate data stores, and defending your trade-offs regarding consistency versus availability.

Be ready to go over:

• Scalability patterns – Load balancing, horizontal scaling, and sharding.
• Data pipelines – Processing high-throughput real-time telemetry and sensor data.
• Fault tolerance – Designing for graceful degradation and automated failover.
• Advanced concepts (less common) – Multi-region active-active architectures and edge computing resilience.

Example questions or scenarios:

• "Design a real-time monitoring and alerting system for distributed rocket telemetry."
• "Architect an API gateway that handles sudden spikes in traffic without failing."

Behavioral and Execution

• This area assesses your resilience, communication style, and ability to deliver results in high-pressure environments. Astra values self-starters who take extreme ownership of their deliverables.
• Strong performance means providing structured, concise STAR-format responses that highlight your personal contributions and collaborative mindset.

Be ready to go over:

• Ambiguity management – Navigating shifting priorities and undefined requirements.
• Cross-functional teamwork – Collaborating with hardware and systems engineering peers.
• Conflict resolution – Handling technical disagreements constructively.
• Advanced concepts (less common) – Large-scale organizational change management and post-mortem facilitation.

Example questions or scenarios:

• "Describe a time when you had to ship a critical feature with incomplete documentation."
• "Tell me about a disagreement you had regarding a system architecture choice."

As a Software Engineer, your day-to-day work centers on designing, building, and scaling the software infrastructure that supports Astra's core mission objectives. You will write robust code for backend services, internal tooling, and data pipelines that ingest and process telemetry from launch vehicles and spacecraft engines. Your deliverables directly influence how reliably engineering teams can monitor, test, and execute missions.

Collaboration is a daily constant in this role. You will work side-by-side with electrical, mechanical, and systems engineers to ensure that software and physical hardware integrate seamlessly. Whether you are building automated test stands or optimizing data ingestion frameworks, you will drive continuous improvement projects that enhance system safety, reliability, and process capability.

You will also take ownership of the full software development lifecycle, from initial system design and coding to code reviews, deployment, and operational monitoring. By fostering a culture of high engineering standards, you help eliminate technical debt and ensure that Astra's software systems remain resilient and scalable as flight operations expand.
