Employer & Industry UsageRaytheon Technologies, defense and aerospace industryLockheed Martin, defense and aerospace industry
Common Search & ComparisonYesYes

The Weekend Raytheon Software Engineer and Weekend Lockheed Martin Software Engineer roles share similar credentials, work environments, and industry usage. Both positions involve working on defense projects, require relevant technical degrees, and often need security clearances. The main differences lie in the specific employer and project focus, but overall, they are comparable roles within the defense aerospace sector.

What are the unique challenges and expectations for a Weekend Raytheon Software Engineer?

As a Software Engineer on weekend shifts at Raytheon, you may face the challenge of working with a smaller onsite team, which often requires a higher degree of autonomy and self-direction. Weekend schedules can involve supporting critical system updates, troubleshooting urgent issues, or ensuring project continuity when weekday teams are unavailable. Collaboration with offsite or remote colleagues is common, so strong communication skills are essential. Additionally, your role may be pivotal in maintaining 24/7 operational support for defense or aerospace projects, making reliability and quick problem-solving especially important.

What are the key skills and qualifications needed to thrive as a Weekend Raytheon Software Engineer?

To thrive as a Weekend Raytheon Software Engineer, you need a solid background in computer science, software development, and proficiency in languages like C++, Java, or Python, typically supported by a relevant degree and security clearance eligibility. Familiarity with integrated development environments (IDEs), version control systems like Git, and Raytheon's proprietary or defense-related software tools is often required. Strong problem-solving abilities, teamwork, and effective communication are essential soft skills, especially when working on critical projects with tight deadlines. These skills ensure the development of secure, reliable software solutions that meet the rigorous standards and operational needs of defense-related projects.

Job description

We're building deeply integrated LLMs into a real product used daily by restoration companies running thousands of jobs. This is not a "prompt engineer" role. You'll design, train, and ship domain-specific language models that automate real workflows and move real revenue.

You will:

  • Own endtoend LLM systems: architecture, training, evals, and iteration
  • Finetune and extend existing models (LoRA, instruction tuning, RLHF)
  • Build and maintain data pipelines from product databases, documents, APIs, and logs
  • Ship reliable, monitored, production models with clear guardrails
  • Collaborate closely with product and engineering to turn messy realworld problems into working systems
  • Build and coordinate the AI engineering team
  • Use Claude Code as a core tool for development, refactors, tests, and experiments

This is for you if:

  • "How does this actually work under the hood?" is your default question
  • You're fine sitting with a hard problem for days and reading papers on weekends to figure it out
  • If there's something interesting to learn or solve, it doesn't matter if it's Saturday or 1 a.m., you're in
  • You build side projects nobody asked for and write cleaner code than anyone requires
  • You're quietly competitive, selftaught in at least one major skill, and think in systems
  • You're slightly allergic to meetings without a clear purpose or owner

Requirements

  • 5+ years of real world experience in ML / AI engineering
  • Proven experience training or substantially contributing to training LLMs (not just calling APIs)
  • Deep understanding of transformers, attention, and training dynamics
  • Strong Python plus PyTorch or JAX
  • Experience with largescale data pipelines and experiment tracking
  • Handson finetuning (LoRA, instruction / SFT, RLHF or similar)
  • Comfortable using Claude Code as part of your daily workflow
  • Able to explain complex systems simply to nontechnical stakeholders and go deep with experts
  • Track record of owning projects endtoend and mentoring other engineers

Nice to have:

  • Distributed training (FSDP, DeepSpeed, Megatron, etc.)
  • Inference optimization (quantization, speculative decoding, vLLM, Triton)
  • Experience shipping LLM features in production SaaS
  • Opensource contributions or published work or patents in ML / NLP
  • Microsoft Foundry experience

Benefits

  • Competitive salary (based on experience and location)
  • Generous PTO
  • Medical, dental, and vision coverage
  • 401(k) plan
  • High ownership and autonomy over your work
  • Direct collaboration with a small team of smart, kind, motivated engineers
  • An environment that values deep work, clear thinking, and real impact
  • Regular team events and offsites
  • Equipment and learning budget to help you do your best work and keep up with the frontier
