Remote (Atlanta, Austin, San Francisco, Seattle) Hybrid Employment $223K – $259K

Ditto is hiring a Senior Software Engineer, Systems FDE

Responsibilities

  • Integrate with Military Avionics Data Buses: Lead the on-site integration of our software with airborne and ground-based platforms by engineering data ingest and translation layers for MIL-STD-1553 and ARINC 429 avionics buses.
  • Implement Tactical Datalink Interfaces: Architect and deploy software interfaces to parse, transform, and route messages from tactical datalinks including Link 16 and Situational Awareness Data Link (SADL), ensuring reliable machine-to-machine interoperability in contested environments.
  • Enable Cursor-on-Target (CoT) Data Flows: Build and maintain robust CoT event pipelines that bridge platform sensor data into the broader C5ISR ecosystem, ensuring operational relevance and low-latency dissemination.
  • Solve Problems in Real-Time: Act as the first line of technical defense, rapidly diagnosing and resolving software, protocol, and integration issues as they arise on operational platforms.
  • Bridge the Gap: Translate the unique, edge-case operational realities you observe (e.g., non-standard bus configurations, latency-sensitive datalink traffic, platform-specific firmware constraints) into actionable technical requirements for the core product development team.

Requirements

  • Clearance Requirement: Must hold an active TS/SCI clearance (Due to federal security clearance requirements, U.S. Citizenship is strictly required for this role).
  • 5+ years of experience in software engineering, embedded systems engineering, or systems integration. This includes hands-on experience writing software that interfaces directly with military or aerospace data buses and protocols.
  • 2+ years of technical experience working with avionics bus standards such as MIL-STD-1553 and/or ARINC 429, including message parsing, bus monitoring, and protocol-level debugging.
  • Demonstrated experience with tactical datalink protocols (Link 16, SADL) and/or Cursor-on-Target (CoT) message formats. You should understand the structure of these data standards and how to translate between them.
  • A highly adaptable, problem-solving mindset, with the ability to navigate ambiguity, move fast, and balance immediate operational fixes with long-term technical fidelity.
  • Strong communication skills, both written and verbal. As the crucial bridge between the operational edge and our core development team, you must be able to translate complex, edge-case technical realities and user workflows into clear, actionable requirements for product engineers.

Nice to Have

  • Direct experience with C5ISR system-of-systems architectures, including an understanding of how sensor-to-shooter kill chains are constructed and maintained across platforms.
  • Experience with real-time embedded operating systems and developing software under hard real-time constraints.
  • Familiarity with flight test or operational test environments, including working with Developmental Test (DT) or Operational Test (OT) teams on military platforms.
  • Experience with software-defined radios (SDRs) or waveform development for tactical communications.
  • Previous experience working directly with DoD platform program offices (e.g., PMA, PEO), with an understanding of the certification and accreditation processes for airborne software.
  • A background in systems programming (e.g., C, C++, Rust) alongside standard scripting, allowing for deep optimization of bus interfaces and protocol handlers. Familiarity with MIL-STD-461 (EMI/EMC) or DO-178C software assurance considerations as they relate to deploying software on airborne platforms.
