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. • Polyglot Proficiency • You are comfortable working across a diverse stack: • – Frontend: Angular / JavaScript / TypeScript. • – Backend/Systems: Python, Java, Go, or C. • – Data: Strong SQL skills and experience with high-performance data structures. • 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. • Career progression and internal mobility opportunities • Unlimited PTO
