Senior Fullstack Software Engineer, Authoring Experience

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it.

Our Senior Software Engineers lead and mentor engineers, delivering high-value products for our customers and infrastructure that enables our business to scale.

As a Senior Software Engineer, you'll be responsible for setting technical direction to enable our product and infrastructure to scale with our business, driving complex projects across our technical stack, and mentoring our talented engineering team. Your past experience will be leveraged to enable and accelerate Vanta's growth.

Our business has found incredible product-market fit and has monetized effectively since the day we signed our first customer. We're growing at a blistering pace, which presents career-defining opportunities for engineers to accelerate their growth and to contribute to a rapidly-scaling company.

Every company Vanta serves connects the tools it already uses: cloud providers, identity systems, HR platforms, code repositories. Vanta Tests are the automated checks that run continuously against that data to confirm security controls are actually in place, and they are how customers earn and prove trust. The Authoring Experience team owns how Vanta Tests are built, deployed, and surfaced to customers, from the APIs and services underneath to the product experiences on top. As a Senior Fullstack Engineer on this team, you will own the services and public-facing customer APIs that turn Vanta's automation platform into products customers touch directly, stitching together systems across the platform to serve them well.

What you’ll do as a Senior Fullstack Software Engineer at Vanta:

Own the architecture and rollout strategy for critical platform services, from initial design through large-scale rollout and migration.

Set the technical bar for how we design, publish, and maintain customer-facing APIs while owning things like security, reliability, and developer experience.

Stitch together services across Vanta's platform to serve customer-facing use cases, designing clear service boundaries and partnering closely with our data-platform teams on access patterns.

Raise the written design bar: drive RFCs and decision records that make architectural decisions durable and shared across the team.

Act as a force multiplier: mentor engineers up to your own level, expand the team's review capacity, and partner with your EM on team health and culture.

Build with TypeScript and Node.js on the backend, contribute to customer-facing experiences in React, and use AI tools to accelerate development and workflows.

How to be successful in this role:

8+ years of backend development building reliable, scalable, fault-tolerant systems.

You've designed and shipped external or public product APIs: contracts, versioning, authentication, and the developer experience around them.

You think in service boundaries and system design rather than any single layer of the stack, with enough data-layer fluency to partner well with dedicated platform teams.

You're comfortable working in a modern frontend codebase (we use React); you don't need to be an expert, but building product end to end is part of the day-to-day here.

Track record driving complex, ambiguous, multi-quarter initiatives to completion, directly and through others.

Experience rolling out or deprecating major systems safely at scale.

Strong written design communication and demonstrated mentorship; you multiply the engineers around you.

Open to using AI to amplify their skills and strengthen their work - demonstrating curiosity, a willingness to learn, and sound judgment in applying AI responsibly to improve efficiency and impact.

Bonus: startup or bias-for-action environments, MongoDB at scale, prior work in security or compliance products.
