Job summary

Scrunch, a Sitecore company, is seeking a Senior Infrastructure Engineer to design, build, and operate the core systems powering our AI-first platform. You will own cloud infrastructure, developer tooling, observability, and reliability at scale, collaborating with engineering teams to ship secure, scalable services on GCP.

The role emphasizes treating infrastructure as software, implementing IaC, edge compute decisions, and building robust monitoring.

Qualifications

• Experience in a high-velocity software development organization.
• Experience designing, building, and operating cloud services at scale (preferably on GCP).
• Experience deploying and operating edge compute functions and knowledge of where to run logic at the edge vs back in the stack.
• Ability to treat infrastructure like software, versioned and deployed via automation (IaC).
• Solid understanding of database performance and scaling patterns and bottleneck identification.
• Familiarity with workflow orchestration tools like Prefect, Airflow, Temporal, Inngest, etc., and designing reliable async pipelines.
• Strong foundation in building observable systems: logging, tracing, metrics dashboards, and alerting.
• Proficiency in production-grade Python code and a software engineering mindset.

Responsibilities

• Design, build, and operate the cloud infrastructure powering Scrunch's platform.
• Own observability, reliability, and performance across services.
• Collaborate with engineering teams to scale infrastructure and make informed edge vs cloud decisions.

Job description

About Scrunch

Scrunch, a Sitecore company, is on a mission to bring brands to an AI-first future—where people increasingly rely on LLMs to discover, understand, and act on information that matters to them.

As AI search and conversational agents replace traditional web search and browsing, Scrunch helps marketing teams rethink how their products and services are discovered and surfaced on AI platforms like ChatGPT, Claude, Gemini, and more—working with AI platforms, not against them. This shift represents the biggest change to marketing since the dawn of the internet.

Today, more than 500 paying brands—including Fortune 500 companies like Lenovo, category-defining brands like Akamai, ADP, Lenovo and breakout startups like Clerk—use the platform.

About the Role

We're looking for a senior Infrastructure Engineer to join our team. This is a high-ownership role responsible for designing, building, and operating the foundational systems that power Scrunch's platform – from cloud infrastructure and developer tooling all the way to observability and reliability. Infrastructure at Scrunch is business-critical: our customers depend on it, and you'll have real impact shaping how we scale.

What We're Looking For:

For this role, we'd like to see candidates that:

• Have experience working in a high-velocity software development organization.
• Have experience designing, building, and operating cloud services at scale, preferably on GCP.
• Have deployed and operated edge compute functions, and understand when it makes sense to run logic at the edge versus further back in the stack.
• Can treat infrastructure like software versioned, tested, and deployed through automation rather than one-off console clicks. Experience with Terraform or similar IaC tools is a plus.
• Posses a solid understanding of database performance and scaling patterns, and have hands‑on experience identifying bottlenecks and addressing them before they become outages.
• Familiarity with workflow orchestration tools or job queue systems such as Prefect, Airflow, Temporal, Inngest, or similar, and are comfortable designing reliable, retryable async pipelines.
• Have a strong foundation in building observable systems, including structured logging, distributed tracing, metrics dashboards, and alerting.
• Are comfortable writing production-quality code (we mostly use python) and approach infrastructure work with a software engineering mindset.

Scrunch is an equal opportunity employer. We welcome people of all backgrounds, experiences, perspectives, and identities. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
