Senior Software Engineer, Build Loop

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 Software Engineer to help us build the next generation of Agentic Codebases

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 an existing vacancy

• Reporting to the Senior Engineering Manager, Developer Productivity

As a Senior Software Engineer, Developer Productivity, you'll:

• Design and build the Nest.js service scaffolding that lets product teams stand up new backend services in our next-generation monorepo

• Implement paved paths, generators, and the platform primitives that make a new service work on day one rather than after a week of wiring.

• Build the seams that let new services run independently of our existing monolith.

• Own the deployment story for services and web applications on Cloudflare, and the interoperability with our existing AWS and Kubernetes estate managed through Pulumi and Argo CD.

• Lead migrations of substantial codebases into the monorepo and turn each one into a repeatable recipe rather than a bespoke effort.

• Partner directly with product teams as platform customers, treating their adoption as the measure of success and their friction as your backlog.

• Raise the leverage of the whole team by encoding what you learn into tooling, generators and agent-assisted workflows, so the next migration costs less than the last.

• Participate in engineering citizenship activities such as co-authoring engineering blogs, strengthening our hiring processes, and leading internal hackathon teams.

About you

Requirements:

• BA/BS Degree or equivalent experience

• 5+ years building and operating backend services in production

• Demonstrated experience in backend service design defining service boundaries, contracts and data ownership, not only implementing within them

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

You'll thrive as a Senior Software Engineer, Developer Productivity, if you:

• Have worked inside a large, heavily-coupled codebase and found the seams: extracting or bypassing functionality incrementally, behind behaviour-preserving contracts

• Are fluent in TypeScript and Node, and comfortable with edge runtimes.

• Have hands-on experience with monorepo tooling at scale (Nx, Turborepo or similar) and understand why build-graph correctness is a product concern rather than a config detail.

• Treat migration work as engineering rather than chores: you budget for the parts that fail silently, verify generated output rather than trusting a green build, and know that bug-for-bug translation beats improvement when the goal is proving nothing changed.

• Enjoy being a platform engineer with real customers — partnering with product teams, adapting the platform to how they actually work rather than requiring them to change, and measuring yourself on their adoption.

• Are comfortable working across cloud boundaries, with a considered view on where a workload belongs and what crossing between clouds costs in latency and spend.

• Communicate decisions in writing well enough that someone can pick up your work from the ticket — and are willing to say plainly when the fast answer and the right answer diverge.

• Stay curious and open to growth — demonstrating a proactive embrace of AI, and actively building and applying fluency in emerging technologies to elevate how we work, drive faster outcomes, and expand collective impact.

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.
