Cyber Software Engineer (Security Tooling) - 50% telework

If you're a developer who likes building the tools that cyber teams actually use when it counts, this one is for you.

Linchpin Software is a small, growing company, and we're hiring a Cyber Software Engineer in Chantilly, VA (50% telework). You'll build custom software, automation, and data pipelines that support cybersecurity operations, incident response, and threat analysis. That means real application development (Python/Django, Angular, Svelte, Postgres, Redis), ETL with Cribl and Splunk, tools that parse forensic images, and the virtualized environments where analysts test and investigate.

You don't need to be a career security analyst. If you're a strong engineer who cares about security and wants a mission behind your code, we want to hear from you.

Here's what we care about, and we hire for it:
- Be helpful. Answer the question, share what you know, and leave things better than you found them.
- Take care of the customer. Our customers have hard missions. We listen, follow through, and make their day easier.
- Be a good teammate. Review the code, jump in on the tough bug, cover for each other, and celebrate the wins together.

We also build software differently. Our engineers use AI-assisted development tools (Claude Code, Codex, GitLab Duo) every day to design, code, test, and debug faster.

What You'll Do:
- Build custom software utilities, automation, and data processing tools for cyber operations
- Develop web applications in Python/Django with Angular or Svelte front ends, backed by Postgres and Redis
- Build secure data ingest pipelines with Python, Cribl, and Splunk
- Write tools and scripts that parse forensic images and artifacts
- Design and maintain virtualized, multi-platform environments for testing and analysis
- Implement CI/CD, version control standards, and automation for fast delivery
- Turn analyst and mission requirements into secure, working software

Required:
- Active Top Secret, TS/SCI, or Intel Agency clearance
- Bachelor's degree
- 8+ years of experience in software engineering, cybersecurity engineering, or infrastructure automation
- Strong programming skills in Python or another modern language used for tooling
- Web application development experience
- Virtualized environments and secure system design
- CI/CD pipelines, version control, and automated builds
- Knowledge of secure data flows, encryption, and cyber operations tools
- Clear communication and a genuine willingness to help customers and teammates

Preferred:
- Django, Angular, or Svelte
- Cribl, Splunk, or other log and data pipeline tools
- Digital forensics or incident response tooling
- Supporting SOC or tactical cyber teams
- Mixed COTS, GOTS, and custom tool environments; multi-enclave operations
- Security+, CISSP, CEH, or DevSecOps/cloud certifications

The Honest Details:
- Location: Chantilly, VA, 50% telework. You'll be on site about half the time, and we mean it.
- Pay: $130,000 - $230,000, based on experience and what you bring.
- Clearance: active Top Secret, TS/SCI, or Intel Agency clearance required. We can't sponsor one for this role.

What You'll Gain:
- Software you build that cyber teams use on real missions
- A mix of application development, data engineering, and security
- A small team where your work is seen and your opinion counts
- Competitive compensation and benefits

If you're a builder who wants your code to matter in cyber operations, apply. A real person on our team reads every application.
