To excel as a Weekend Software Engineer at this compensation level, you need advanced programming expertise, deep computer science knowledge, and a strong track record of delivering complex projects, often demonstrated through a computer science degree or equivalent experience. Mastery of relevant development frameworks, cloud platforms, and version control systems, along with familiarity with automated testing and CI/CD pipelines, is typically required.

What is a weekend software engineer 300K?

A Weekend Software Engineer 300K is a software engineer who works primarily or exclusively on weekends, often for companies that require ongoing development or support outside of regular business hours. The '300K' typically refers to the annual salary, indicating a highly competitive compensation package for weekend-only work. These positions are sought after by experienced engineers who prefer flexible schedules or have other commitments during the week. Responsibilities can include coding, troubleshooting, deploying updates, and collaborating with teams remotely. Such roles are usually found in tech companies that operate globally or need continuous software maintenance.

What are common challenges faced by weekend software engineers, and how can they be addressed?

Weekend Software Engineers often face the challenge of limited team interaction and asynchronous communication, since most colleagues work standard weekday hours. To address this, it's important to document work thoroughly, make use of collaborative tools, and proactively communicate progress and blockers. Additionally, managing a condensed work schedule requires strong time management and prioritization skills to ensure key tasks are completed efficiently. Leveraging clear handoffs and regular updates with the team can help maintain project momentum and integration.

Job Description

OUSW (R&E) is seeking a highly skilled senior software systems engineer to be the technical lead for a complex project involving the design, development, integration and assessment of complex System of Systems (SoS) architectures for multi-domain autonomous uncrewed platforms (air, surface, and subsurface) in tactical operations over contested radio networks.

This role combines software architecture and systems engineering expertise to prototype advanced, multi-domain autonomy, AI-enabled command and control, and distributed system-of-systems operations. The ideal candidate is a trusted advisor and technical expert with experience guiding model-based systems engineering activities, SoS integration, and test activities across virtual, hardware-in-the-loop (HIL), and live experimentation venues.

Key Responsibilities

  • Lead the development, implementation and evolution of MOSA-aligned SoS architecture to integrate uncrewed platforms across multiple domains.
  • Lead the software integration of advanced autonomy capabilities for mission orchestration, multi-vehicle coordination, and human-supervised command and control of Agentic-AI based solutions from multiple industry partners.
  • Lead the engineering of resilient command, control, and data exchange mechanisms over tactical radio networks (e.g., MANET, Link-16, SATCOM) to ensure operations in degraded, disconnected, or contested environments.
  • Coordinate technical integration across software products from multiple industry partners into vehicle platforms and payloads from other industry partners.
  • Coordinate System Eng & Architecture activities with M&S and test activities on a continuous basis to ensure alignment throughout execution.
  • Serve as a key interface for government stakeholders, industry partners, and technical teams, aligning objectives with OUSW(R&E), Service stakeholders, and transition partners.
  • Provide technical guidance for digital engineering, mission simulation, and test planning activities.
Qualifications
  • Bachelor's or Master's degree in Computer Science, Systems Engineering, Software Engineering, or a related technical discipline.
  • 10+ years of proven experience in software architecture, systems engineering, and integration within the defense aerospace or maritime sectors.
  • Deep working knowledge of unmanned and autonomous systems, cross-domain platform integration, and complex System of Systems (SoS) engineering.
  • Strong understanding of RF communications, tactical data links, mesh networking, and secure communications protocols suitable for defense applications.
  • Cognizant of state of the technology in Agentic AI and multi-agent systems for autonomy capabilities.
  • Experience leading and collaborating with cross-functional teams, including interactions with the Joint Staff, Combatant Commands, Military Services, or OSD organizations.
  • Proven ability to communicate complex technical findings to senior leadership, technical experts, and non-technical stakeholders.
  • Active Top Secret clearance (TS/SCI preferred).

Additional Information

Work Environment

  • Working conditions are normal for an office environment.
  • Fast paced, deadline-oriented environment.
