Senior Fullstack Engineer

Beyond
San Francisco, CA Full Time
POSTED ON 1/5/2026
AVAILABLE BEFORE 2/3/2026
Beyond Mission Capable Solutions (BMCS) LLC is a trusted partner in the cyber community.

Our clients in the Department of Defense, Air Force, Space Force and Federal Aviation have adopted our solutions for cybersecurity acquisition, implementation, and operational risk management challenges while planning for emerging security threats. As technologically sophisticated attacks are increasing, we are looking to grow our team of laser-focused cybersecurity engineers.

About The Role

Our partner is building an AI platform that takes over the complex and time-consuming work of coordinating freight for manufacturers and distributors. From booking and tracking to managing shipments end-to-end, this AI platform lets operations teams hand off their entire logistics function and scale at a fraction of the cost of adding more headcount.

The company has reached a major revenue inflection point, backed by Y Combinator (S24) and a $3.3M seed round, and is growing quickly to meet accelerating customer demand.

As a Founding Engineer, you’ll work closely with the founding team to design and build core infrastructure and AI systems that will shape the future of how goods move. This is a hands-on role with real ownership from day one — perfect for someone who thrives in fast-paced, high-impact environments.

What You’ll Do

  • Scale architecture for growth Design and optimize systems that can support traffic surges up to 10× current levels, maintaining real-time performance and reliability as the customer base expands.
  • Build and automate AI loops Develop the tooling to monitor, evaluate, and continuously retrain AI models in production, ensuring the system gets smarter with each new edge case.
  • Own the product end-to-end Instead of working from a backlog of tickets, you’ll receive real problems, speak directly with customers, design solutions, build them, and ship to production.
  • Develop seamless integrations Create rich, two-way experiences with platforms like Slack and Microsoft Teams — including slash commands, real-time shipment dashboards, and alerting systems that meet customers where they work.

Job Qualifications

  • Product-driven builder You care about solving real problems, not just writing elegant code. Whether you have 2 or 10 years of experience, you take pride in shipping impactful products.
  • High-agency problem solver You’re comfortable navigating ambiguity, move quickly to find answers, and don’t hesitate to jump on a call with a customer to get to the root of an issue.
  • Full-stack versatility When given a goal like “get this customer live,” you’ll do whatever it takes — from building UI to extending APIs to fine-tuning models — to make it happen.

Compensation & Benefits

  • Competitive salary ($110K–$180K, depending on experience)
  • Meaningful equity (~1% as an early team member)
  • Full medical, dental, and vision coverage (100% paid)
  • High-trust, high-ownership culture with no micromanagement
  • A chance to define the future of AI in logistics
