Principal Software Engineer
Truffle Security Co.About the role
About us
Truffle Security is a cybersecurity company on a mission to make secrets easier to detect, verify, and remediate across modern software environments. Built on the popular open-source TruffleHog™ secrets scanning platform, the company's enterprise solution gives security and engineering teams everything they need to find exposed credentials, understand which ones are active, and act on them with confidence.
With support for 800+ credential types, Truffle Security continuously monitors non-human identities (NHIs) and their associated secrets across code repositories, SaaS applications, wikis, and cloud systems. It goes beyond detection by verifying which secrets are live, analyzing their scope of access, and streamlining remediation through automated workflows and lifecycle management so teams can prioritize what to revoke and confirm it's done without manual follow-up.
Trusted by organizations including NVIDIA, Chick-fil-A, and OpenAI, Truffle Security helps security and engineering teams stay ahead of secrets risk.
About the Role
We’re looking for a Principal Software Engineer to serve as a senior technical leader across Engineering. This is a hands-on role focused on improving architecture, scalability, reliability, and engineering quality across our systems.
We have a strong team of Senior and Staff engineers, and we’re looking for someone who can make that team even more effective. This role is about creating leverage across Engineering: improving the quality of technical decisions, mentoring experienced engineers, establishing durable architecture and engineering practices, and helping teams move faster without sacrificing reliability or maintainability.
We’re also changing how we build software. Our engineering team is putting more emphasis on using agentic development tools effectively. The goal is not to replace engineering judgment, but to improve planning, implementation, testing, review, and overall leverage. This role will help shape practical workflows for using these tools well while maintaining high standards for quality, security, and maintainability.
You’ll work closely with engineering leadership, product, infrastructure, and security teams to shape long-term technical direction while helping teams move quickly and responsibly.
What you'll be working on
- Improving architecture across backend services and platform infrastructure, and defining long-term architectural strategy and technical standards across teams
- Establish engineering standards that improve consistency, maintainability, reliability, and operational readiness
- Scale distributed systems and improve performance across core services
- Improve production engineering practices, including observability, testing, incident response, and post-incident review
- Identify and reduce high-impact technical deby
- Improve developer tooling, workflows, and engineering productivity
- Help teams use agentic development tools effectively across planning, implementation, testing, review, and validation
- Partnering with product and infrastructure teams on scalable, resilient systems and subsequently simplifying systems and reducing organizational complexity as the platform scales
- Mentor Senior and Staff engineers through architecture reviews, technical coaching, and project guidance
- Serve as a trusted technical advisor for difficult engineering and architectural decisions
Areas You May Work In
- Distributed systems and service architecture
- Platform reliability and observability
- Scalable ingestion and scanning infrastructure
- Multi-tenant systems and cloud infrastructure
- Internal developer tooling
- Frontend architecture across React and TypeScript applications
What We’re Looking For
Required Qualifications
- Experience operating as a Principal Engineer, Architect, or senior Staff+ engineer
- Deep experience designing and operating distributed systems in production
- Strong backend engineering experience, ideally in Go or a similar language
- Strong architectural judgment and systems thinking, with the ability to simplify complex systems and make pragmatic technical trade-offs
- Experience leading complex technical projects across teams
- Proven ability to mentor and develop senior engineers
- Strong communication and technical leadership skills
- Strong operational mindset around reliability, scalability, observability, and performance
- Ability to balance long-term technical quality with pragmatic execution
- Comfort operating in fast-moving, ambiguous environments
- Bias toward ownership, execution, a
