Principal Software Engineer, Truffle Security

• 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, and driving technical clarity in ambiguous environments
• Practical experience using agentic or AI-assisted development tools in professional engineering workflows
• Experience introducing shared workflows, prompts, rules, coding agents, or internal tooling that improve engineering productivity
• Good judgment around where automation improves leverage, how AI-assisted work should be reviewed, and when direct engineering ownership is needed
• You should be comfortable working across modern distributed systems, cloud-native environments, and AI-assisted engineering workflows
• If what we’re doing resonates with your values, we’d love to have you apply even if you don’t check all of the boxes or match the job description to a tee

Desirable

• 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
• 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
• Our primary technologies include:
• Go, React, TypeScript, Django/Python, PostgreSQL, Kubernetes, Docker, GCP, CI/CD and observability tooling
• Agentic development tools such as Cursor, MCP integrations, and other AI-assisted engineering environments
• You do not need experience with every technology listed here
• You’ll be Truffle’s first Principal Engineer and help define what senior technical leadership looks like here
• You’ll have broad influence across architecture, engineering standards, operational maturity, and technical strategy
• You’ll work with a strong team of Senior and Staff engineers who care about technical quality and thoughtful engineering
• You’ll help shape how Truffle uses agentic engineering tools in a practical, high-judgment way
• You’ll help build the technical foundation of a growing security company solving difficult infrastructure and developer security problems
• Your impact will extend well beyond your own code. This role is about making the entire engineering organization more effective
