Senior Software Engineer, Operator Tools

As a Senior Software Engineer on the Operator Tools team, you will design and build desktop applications and interfaces used by Elroy's operators and engineers, including mission planning tools, real-time telemetry displays, diagnostic interfaces, and ground support workflows. You will collaborate with engineers across embedded systems, control systems, flight physics, and power electronics, requiring systems intuition to understand the data and workflows. The role involves developing communication interfaces between desktop tools and embedded systems, contributing to ground support tooling, and building web-based data analysis and visualization tools connected to cloud databases.

Responsibilities

• Desktop application development for mission planning, real-time telemetry, and vehicle diagnostics (Qt, Electron, or similar native/hybrid desktop frameworks)
• Visualization and data presentation for complex, time-series, and spatial data from autonomous systems
• Communication interfaces between desktop tools and embedded systems (serial, UDP, custom protocols, MAVLink or similar)
• Ground support tooling: calibration workflows, pre-flight checks, log analysis, and fleet management interfaces
• Collaboration with the simulation infrastructure team to expose cloud batch results in accessible, actionable UI
• Web-based data analysis and visualization tools that connect to cloud databases. Think interactive flight data replay, post-mission analysis dashboards, and fleet-level trend reporting
• C++ and Python development across the stack; comfort moving between application logic and lower-level interfaces
• Contribution to the team’s overall software architecture and developer experience, particularly for tooling and internal platforms

Requirements

• 5+ years of professional software development, with experience across desktop application development and web-based tools, ideally both
• Strong C++ and/or Python skills; experience structuring non-trivial desktop applications
• A track record of building UIs that are usable under real-world operational conditions, not just demos
• Ability to work across the stack: from application logic down to protocol parsing or up to data visualization
• Experience integrating applications with real hardware or real-time data sources
• High standards for software architecture, API design, and internal tooling quality

Nice to have

• Experience in aerospace, defense, robotics, or other safety-critical domains
• Familiarity with embedded software concepts: you don’t need to write firmware, but you should be able to read it, build it, run it, and understand its constraints
• Experience with cloud-based simulation or batch processing infrastructure
• Exposure to geospatial visualization, 3D rendering, or time-series data at scale

Benefits

• Competitive salary
• Equity ownership in a rapidly growing advanced aerospace company
• Comprehensive medical benefits
• 401(k) with company contribution + Roth IRA
• Free daily lunch provided onsite
• Flexible time-off policy
• 3 months of paid parental leave
• Employee assistance program with 24/7 support
