## The Role

We're looking for a Principal Engineer to drive technical strategy and architecture across our engineering organization. This is our highest Individual Contributor role—you'll set technical direction organization-wide, solve the most complex problems, and influence teams without formal authority.

This is NOT a management position. You won't have direct reports or conduct performance reviews. You'll partner with Engineering Managers and Directors who handle people leadership while you own technical vision and strategy. Your focus is organizational-level technical impact: setting architecture direction, driving cross-team initiatives, and ensuring our systems scale for the next 5 years.

The ideal candidate is a deeply technical engineer who thinks strategically about systems, people, and organizations. You're energized by influencing technical decisions at scale, not just building features yourself.

## What This Role IS

- **Organization-level impact:** You'll shape technical strategy across 12 engineering teams, not just one team or project
- **Technical strategy ownership:** You'll set architectural direction, evaluate technologies, and define technical standards organization-wide
- **Cross-team leadership:** You'll drive initiatives spanning multiple teams, building consensus and alignment without authority
- **Complex problem solver:** You'll tackle our hardest technical challenges—the problems that span teams and require deep expertise
- **Senior IC mentor:** You'll mentor Staff Engineers and help them grow toward Principal-level impact

## What This Role is NOT

- **Not a Staff Engineer:** Staff Engineers focus on team-level impact. Principal Engineers work at the organizational level, influencing technical direction across multiple teams.
- **Not an Architect who doesn't code:** You'll spend 15-25% of your time hands-on with code, proof of concepts, and technical spikes. We don't have architects disconnected from implementation reality.
- **Not a CTO or VP Engineering:** You won't manage people, set budgets, or handle organizational politics. This is a technical leadership role focused on systems and architecture, not management.
- **Not a project manager for technical initiatives:** You'll lead through technical influence and expertise, not project management. We have TPMs for coordination.

## Objectives of This Role

- Define and communicate a 3-year technical roadmap for our platform architecture
- Lead the design of our next-generation distributed data layer (our biggest technical challenge)
- Establish architectural review processes and technical standards across all engineering teams
- Reduce cross-team technical debt through strategic refactoring initiatives
- Mentor 3-4 Staff Engineers toward Principal-level impact and organizational thinking

## Responsibilities

- Set technical strategy and architecture direction for the entire engineering organization
- Lead cross-team technical initiatives from conception through implementation
- Design large-scale distributed systems that will handle 100x current load
- Make high-stakes technical decisions with long-term organizational impact
- Influence engineering teams on technical direction without formal authority
- Conduct architecture reviews and provide guidance on complex system designs
- Define technical standards, patterns, and best practices organization-wide
- Evaluate emerging technologies and make recommendations for adoption
- Write code for proof of concepts, critical system components, and technical spikes
- Present technical strategy to engineering leadership and executive team
- Mentor Staff Engineers on architectural thinking and organizational impact

## Required Skills and Qualifications

- 12+ years of software engineering experience, with 4+ years at Staff Engineer level or equivalent
- Demonstrated experience driving technical initiatives across multiple teams (not just within one team)
- Deep expertise in distributed systems design and large-scale architecture
- Track record of setting technical strategy, not just executing on others' strategies
- Strong ability to influence technical decisions across teams without formal authority
- Experience mentoring senior engineers and helping them grow to the next level
- Excellent communication skills for presenting technical strategy to both engineers and executives
- Ability to balance long-term technical vision with pragmatic short-term decisions

## Preferred Skills and Qualifications

- Experience with our core technologies (Kubernetes, Kafka, PostgreSQL, Go, or similar)
- Background in developer tools, infrastructure, or platform engineering
- Experience defining technical standards and review processes at scale
- Published technical writing, conference talks, or recognized thought leadership
- Experience working with distributed engineering teams across time zones
- Previous Principal Engineer, Distinguished Engineer, or equivalent role at a technology company

## Tech Stack

- **Languages:** Go (primary), TypeScript, Python
- **Databases:** PostgreSQL, Redis, ClickHouse
- **Messaging:** Kafka, NATS
- **Infrastructure:** Kubernetes, Terraform, AWS
- **Observability:** Prometheus, Grafana, OpenTelemetry
- **CI/CD:** GitHub Actions, ArgoCD
- **Collaboration:** GitHub, Linear, Notion, Slack

## Compensation and Benefits

**Salary:** $240,000 - $320,000 (based on experience)

**Equity:** 0.15% - 0.25% (4-year vest, 1-year cliff)

**Benefits:**

- Medical, dental, and vision insurance (100% covered for employees and dependents)
- Unlimited PTO with 20-day minimum encouraged
- $5,000 annual learning budget (conferences, courses, certifications)
- $2,500 home office setup allowance
- 401(k) with 6% company match
- 16 weeks paid parental leave
- Fully remote with optional access to SF and NYC office spaces
