at the company (View all jobs)

San Francisco Bay Area Hybrid

the company is the leading AI-first digital analytics platform, helping over 4,300 customers—including Atlassian, Burger King, NBCUniversal, Square, and Under Armour—build better products and digital experiences. With powerful AI Agents embedded across our platform, teams can analyze, test, and optimize user experiences faster than ever. Ranked #1 across multiple categories in G2’s Fall 2025 Report, the company is the best‑in‑class solution for product, data, and marketing teams. Learn more at the company.com.

As an organization, we deliver for our customers by living our values. We operate from a place of humility, take ownership of problems and successes, approach challenges with a growth mindset, and put our customers at the center of everything we do.

the company’s Commitment to Diversity Equity & Inclusion (DEI): the company believes that diversity enables the creation of better products, improves the ability to solve complex problems, and drives more powerful solutions. We strive to create an environment of inclusion—one focused on psychological safety, empathy, and human connection—that will allow employees of all backgrounds to thrive.

What You’ll Do

Frontend architecture: Own and evolve the architectural foundations of our frontend platform — module boundaries, micro-frontend patterns, shared component/design-system infrastructure, and state management strategy.

Application performance: Diagnose and fix systemic performance issues (bundle size, load time, runtime performance, rendering bottlenecks); establish performance budgets and guardrails that scale across teams.

Developer experience & tooling: Build and maintain the build systems, local dev environments, CI/CD pipelines, linting/codegen, and internal tooling that other engineers depend on daily.

Software factory / agentic workflows: Continuously identify the biggest bottleneck in the engineering workflow and build AI‑agent‑driven automation to remove it, then move to the next one. For example, once code and PR generation stopped being the constraint, the bottleneck shifted to validation — and that's the next thing to automate. This is an ongoing, iterative practice of finding where engineers are spending unnecessary manual effort and systematically eliminating it with agentic tooling.

Technical leadership: Set technical direction and standards for the frontend org; mentor senior/staff‑track engineers; review architecture proposals from other teams that touch shared frontend infrastructure.

Cross‑functional partnership: Work closely with product engineering teams, design systems, and platform/infra teams to make sure foundational investments actually solve real product‑team pain points.

What We’re Looking For

Real world software engineering experience, with a track record operating at Staff level or equivalent scope/impact.

Deep expertise in modern frontend architecture (React or equivalent component frameworks) combined with strong infrastructure/systems engineering instincts — you’re as comfortable in build tooling, CI/CD, and dev environments as you are in application code.

Demonstrated experience improving frontend application performance at scale (bundle optimization, rendering performance, load‑time metrics).

Experience designing and shipping internal developer tooling or platform infrastructure that measurably improved developer velocity.

Hands‑on experience with AI‑agent‑driven or LLM‑powered engineering workflows (agentic coding tools, autonomous pipelines, AI‑assisted codegen/migration) — or a clear point of view on how to build them.

Strong technical judgment and the ability to drive consensus on ambiguous, cross‑cutting architectural decisions without heavy‑handed authority.

Excellent communication, written and spoken — this role requires influencing through documents and proposals as well as in design reviews and cross‑team discussions, as much as through code.

Nice to Have

Experience with monorepo tooling, micro‑frontend architectures, or large‑scale frontend platform migrations.

Familiarity with design systems and component library architecture.

Prior experience building "agent harness" style infrastructure: eval frameworks, agent orchestration, or tool‑use frameworks for LLMs.

Who We Are

the company is filled with humble, life‑long learners who are eager to help one another and the company succeed. Our values of growth mindset, ownership, and humility are core to the way we work: we’re tenacious in the face of challenges, we take the initiative to solve problems that drive our shared success, and we operate from a place of empathy and openness, seeking to understand many points of view.

The Product

the company is a digital analytics platform—we help companies capture data they can trust, uncover clear insights about customer behavior, and take faster action. This empowers teams to build better product experiences that drive business growth. We’re super proud of what we’ve built and continue to expand: a platform that empowers companies to thrive in the digital era.

We care about the well‑being of our team: We offer competitive pay and benefits packages that reflect our commitment to the health and well‑being of our Ampliteers.

Some of our benefit programs include:

Excellent Medical, Dental and Vision insurance coverages, with 100% employer‑paid premiums for employee Medical, Dental, Vision on select plans

Flexible time off, paid holidays, and more

Generous stipends to spend on what matters most to you, whether that’s wellness (monthly), commuter transit/parking (monthly), learning and development (quarterly), home office equipment (annual), and much more
