Cyber Software Engineer (Security Tooling) - 50% telework

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

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

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.
