Senior Software Engineer, Marketing Engineering

The Opportunity

We're hiring a Senior Software Engineer to own the implementation, inventory, monitoring, and performance of every third-party integration that touches our numerous web properties: conversion pixels, trackers, first- and third-party analytics, ABM, APIs, cAPIs, cookie consent banners, and whatever the next law or vendor throws at us next quarter.

This is not a migration. It is not a zero-to-one build. It's a plane flying well, and the person you're backfilling left it in good standing with thorough notes. You'll be taking over the controls, tuning the instruments, and working through a backlog of challenging and interesting projects. If you're looking for a stepping stone to something else, this isn't it. If you want to deeply nerd out on analytics, engagement, performance, and the craft of getting third-party implementations right, read on.

What You'll Do

About 90% of your time will be spent on third-party integrations: implementing them, inventorying them, tracking them, monitoring their uptime and the veracity of their data streams, and optimizing their performance. These integrations are helping the business get a view into how our campaigns, organic traffic, and other initiatives are actually working.

The remaining 10% is where the variety lives. Our stack runs from AWS and Cloudflare Workers to React/Next.js, into a WordPress theme, a Zendesk theme, Discourse, and more. You'll jump in across JavaScript, TypeScript, a bit of PHP, JSON, YAML, and whatever implementation technique a given platform demands. What you ship on Monday may look nothing like what you ship on Friday.

You'll sit at the intersection of Leadership, Legal, Marketing Engineering, and our third-party vendors. All four will look to you to figure it out, and in a way that meets each of their needs. Knowing where to strike the balance between speed, compliance, quality, and performance shifts with every implementation.

About You

You thrive in ambiguity and dive in anyway. This corner of the ecosystem shifts constantly with each new law, vendor change, and business need, and that's exactly what you find interesting about it.

You can step onto an established, functioning system, get up to speed quickly, and start forming opinions about what you see, without needing to rewrite everything to feel ownership.

You communicate effectively with technical and non-technical stakeholders, make sound and informed judgment calls under competing priorities, and adapt quickly when direction shifts. This role has regular exposure to Leadership, so you bring a composed, transparent approach to your work and stay steady when the work gets fast or messy.

You also work well as a specialist inside a team of six engineers that can help where you may need it. There will be lots of solo adventures in your work, and also times when you can’t get a project done without 5 other people involved.
