Job description

Full Stack Developer (AI & Cybersecurity)

We are looking for a Full Stack Developer who functions like a “Product Engineer”—someone who doesn’t just write code to tickets, but understands the why behind the product. You will be a founding member of our AI-driven evolution, moving with the urgency of a startup and the precision of a world-class security firm.

This is a high-impact, hands-on role focused on velocity and innovation. You will architect and ship production-ready software that integrates LLMs and Generative AI into our core security stack. You will work directly with our C‑suite and a lean team of veteran developers to turn ambitious ideas into reality.

Core Responsibilities

• Ship at Velocity Rapidly prototype and deploy new features, moving from whiteboard concept to production-ready code in days, not months.
• Architect for Scale Design and implement scalable systems that handle massive data throughput without sacrificing development speed.
• Full-Stack Ownership Take complete end-to-end ownership of projects, from low-level backend performance (Go/C) to intuitive frontend experiences (Angular).
• AI Integration Build and refine AI-powered features using LLMs, LangChain, and PyTorch to give our customers an “unfair advantage” against cyber threats.
• Eliminate Friction Identify bottlenecks in our engineering lifecycle and implement tools/processes to improve overall team velocity.
• Collaborative Innovation Partner with C-level leadership to translate high-level business goals into technical roadmaps.

Key Candidate Attributes (The “Ideal Fit”)

You are a polyglot developer who is “tool-agnostic” and cares more about solving the problem than the specific language used.

• Experience 4+ years of experience building and deploying complex systems within AWS environments.
• The AI Edge Hands-on experience building with LLMs and GenAI frameworks (LangChain, PyTorch, or similar). You understand how to prompt, fine-tune, and integrate AI into functional software.
• Product Mindset Proven track record of building complete systems. You understand how the frontend interacts with the API, and how the API interacts with the database/cloud layer.
• Executive Communication The ability to explain complex technical trade-offs to non-technical stakeholders and C-level executives.
• The “Startup” DNA A solutions-oriented mindset with a high degree of independence. You don’t wait for permission to fix a problem.

Why threatER?

• Impact You are building tools that protect critical infrastructure and global enterprises from sophisticated cyberattacks.
• High Agency We minimize red tape. If you have a better way to build something, you’ll have the autonomy to do it.
• Elite Team Work alongside highly experienced developers who value pragmatism, high engineering standards, and shipping.
• Location Join us in the heart of the Tysons, VA tech corridor in a collaborative, high-energy on-site environment.

Benefits We Offer

• Competitive market-based compensation
• Medical, Dental, Vision and Life
• 401k – matching both your pre-tax and/or Roth elective contributions, dollar for dollar, up to 4% of your eligible pay. Immediately eligible to participate upon employment and contributions are 100% vested.
