Senior Software Engineer, Full-stack

About Us

Ground operations are the backbone of aviation, yet they remain largely manual and fragmented. Moonware is changing that.

HALO, our flagship product, is used by airfield teams to optimize flight turnarounds. It serves as a centralized operating layer to manage and oversee tasks, communications, and performance. By enhancing operational visibility and control, HALO enables faster, more reliable, and standardized ground operations.

Our vision is to provide fully autonomous ground operations. HALO serves as the digital infrastructure to support that transition, connecting data, people, and machines to build toward automated airfields.

Moonware’s team combines aviation operations domain knowledge together with software and engineering expertise from top Silicon Valley tech companies. As we scale, we’re expanding the Moonware ecosystem to support the next generation of air transportation.

About the role

Moonware is seeking a full-stack minded Senior Software Engineer to contribute and own application development for HALO, our next-generation Ground Traffic Control platform.

This is a true end-to-end role: you’ll work directly with ground crews and airport stakeholders to understand operational needs, and design and build distributed systems that power mission-critical decisions on the tarmac. From backend services to internal tools and user-facing applications, you’ll own and deliver features across the stack. You’ll collaborate closely with hardware partners, frontline users, and engineering peers to ship reliable, high-performance software that drives efficiency in ground operations. 

Your responsibilities include:

• End-to-end product development: design, build, test & maintain critical features

• Work across the stack: write robust services, build internal tools, expose well-designed APIs, and ship reliable features to customers

• Work with real-time operational data to deliver accuracy, usability, and performance in the apps you build

• Collaborate with field users and vendors to understand edge cases, device quirks, and operational needs, then reflect those insights in technical design

• Build scalable systems that ensure reliability and performance under extreme load

• Ensure data integrity through automated testing, monitoring, and observability across the pipeline

• Contribute to ongoing improvements in our data model, user flows, and system observability

• Help establish best practices in frontend architecture, backend infrastructure, and CI/CD workflows

• Ensure scalability, security, and resilience across the stack

Requirements:

• 4+ years of experience as a full-stack, software or data engineer, preferably in a real-time or operational environment

• Deep familiarity with operating data pipelines (e.g. Kafka, Airflow, Debezium, etc) and cloud-native infrastructure (e.g. AWS, GCP, Terraform)

• Strong experience with SQL and NoSQL databases, schema design, and performance tuning

• Proficient in one or more backend languages (Go, Java, or similar), and able to write clean, maintainable code

• Front-end experience in React, Angular, or similar JavaScript framework

• Experience exposing and consuming REST and/or gRPC APIs

• A product mindset: you enjoy talking to users and vendors to deeply understand problems before solving them

• Excellent problem-solving and communication skills

• Comfortable working in startup environments with high ownership and autonomy

This role might be for you if:

• Aviation, autonomy, and mobility excite you

• You like to rapidly iterate, learn on the fly, and wear many “hats”

• You thrive in real-world, field-connected systems, not just clean data warehouse problems

• Love leading technical teams to develop solutions for customers

Nice to haves:

• Experience with real-time, event-driven systems (MQTT, WebSockets, etc)

• Background in aviation, mobility, IoT, or logistics

• Previous experience at an early-stage startup

• Experience with sensor data, GPS, or fleet telemetry
