Senior Infrastructure Engineer

Webflow is the agentic web marketing platform for modern marketing teams, helping organizations build, manage, and optimize high-performing web experiences that drive predictable growth and strengthen brand trust. Building at Webflow will need grit, because we move fast, without ever sacrificing craft or quality.

We’re looking for a Senior Infrastructure/SRE Engineer to improve the reliability and stability of the customer-facing production infrastructure behind Webflow’s Convert pillar.

Convert owns a suite of products that give marketing and growth teams the tools to experiment, personalize, and drive real revenue from their web presence, including Webflow Analyze, Optimize, AEO, and Campaigns. As tens of thousands of projects launch on Webflow each month, you’ll help keep the platform secure, scalable, and dependable for the people who rely on it.

Much of what Convert delivers depends on data: high-volume event ingestion, real-time and analytical data stores, and pipelines that turn visitor behavior into reporting, experiments, and personalization. You’ll own the reliability, performance, and cost of this data infrastructure, including streaming and batch pipelines and analytical databases. You’ll set SLOs, build observability, plan capacity, and make sure data stays fresh, accurate, and available as volume grows.

The next chapter is ambitious. We’re serving some of the world’s largest enterprises and rethinking what an AI-native conversion platform can be. You’ll work across a large, revenue-generating system, partner with the engineers who build on it, and help decide how it needs to evolve.

About the role:

• Location: Remote-first (Argentina)

• Permanent, full-time employee (this is not a contractor position)

• Application Information:

  • Application deadline: applications accepted on an ongoing basis until position is closed and filled

  • This posting is for a new position.
    

As a Senior Infrastructure/SRE Engineer on the Convert pillar, you'll:

• Own and evolve the cloud infrastructure behind the Convert products, including compute, serverless, networking, and cloud operations on AWS.

• Build and maintain our infrastructure-as-code foundation in Pulumi, and evolve the patterns and shared components other teams build on.

• Improve scalability and reliability of distributed, event-driven systems, including our Druid, MongoDB, and Airflow workloads, with a focus on low latency.

• Make observability the foundation of how we operate. Improve the dashboards, alerts, and SLOs for the systems you own so we catch issues before customers notice, and on-call pages are actionable instead of noisy.

• Lead projects from design through launch that move team and engineering org goals.

• Write and review maintainable, tested, performant code and automation, and raise the quality bar for the team.

• Build AI-powered automation, from policy-as-code and drift detection to LLM-assisted runbook generation, and use AI tools in your daily work.

• Help the team build reliable systems.

About you

Requirements:

• BA/BS degree or equivalent experience

• Business-level fluency to read, write and speak in English

You’ll thrive as a Senior Infrastructure/SRE Engineer if you:

• Have 5+ years owning and operating cloud infrastructure in a customer-facing environment with little tolerance for downtime. You come from infrastructure, SRE, or cloud engineering with a love of automation and code, or from software engineering with a deep interest in cloud infrastructure and distributed systems.

• Have deep hands-on experience with AWS and a clear view of what good cloud operations look like.

• Have used infrastructure as code (Pulumi or Terraform) and prefer changes made through code, not consoles.

• Have operated high-throughput, data-intensive distributed systems in production, such as Druid, MongoDB, or Airflow, and understand scalability, fault tolerance, consistency trade-offs, and performance tuning.

• Are fluent in Python or TypeScript/Node.js for automation and tooling, and can read and work in Java services.

• Treat observability as the basis of operations: you design SLOs, dashboards, and alerts so that issues surface before customers notice and pages are actionable.

• Handle incidents well, including on-call and blameless postmortems, and fix the root causes behind them instead of just closing tickets.

• Want to improve developer productivity, with CI/CD, tooling, and paved paths that let product engineers ship without owning infrastructure.

It would be a bonus if you had even one of the following:

• Experience with Apache Spark, Airflow, or TensorFlow.

• Familiarity with Kafka or other event streaming platforms.

• Experience building AI-assisted infrastructure tooling, including cost optimization loops, anomaly detection, or policy-as-code with LLM assistance.

• Experience contributing to multi-region architecture including data residency, regional failover, or latency-based routing.

Our Core Behaviors

• Build lasting customer trust. We build trust by taking action that puts customer trust first.

• Win together. We play to win, and we win as one team. Success at Webflow isn't a solo act.

• Reinvent ourselves. We don't just improve what exists, we imagine what's possible.

• Own it all the way. We move fast because the moment demands it, and we hold ourselves accountable to deliver outcomes — for each other, and for customers.

Benefits

• Ownership in what you help build. Every permanent Webflower receives equity (RSUs) in our growing, privately held company.

• Health coverage that actually covers you. Comprehensive medical, dental, and vision plans for full-time employees and their dependents, with Webflow covering most premiums.

• Support for every stage of family life. 12 weeks of paid parental leave for all parents and 6+ weeks of additional paid leave for birthing parents. Plus inclusive care for family planning, menopause, and midlife transitions.

• Time off that’s actually off. Flexible vacation, paid holidays, and a sabbatical program to help you recharge and come back inspired.

• Wellness for the whole you. Access to mental health resources, therapy and coaching.

• Invest in your future. A 401(k) with 100% employer match (up to $6,000/year) in the U.S., and support for retirement savings globally.

• Monthly stipends that flex with your life. Localized support for work and wellness expenses — from Wi-Fi to workouts.

• Bonus for building together. All full-time, permanent, non-commission employees are eligible for our annual WIN bonus program.

Temporary employees may be eligible for paid holiday and time off, statutory leaves of absence, and company-sponsored medical benefits depending on their Fixed Term Contract and their country/state of employment.
