About Longitude Ads

Longitude Ads builds and operates monetization infrastructure for digital publishers. We manage, optimize, and scale programmatic advertising across display and video for a variety of publishers ranging from Jounce Bellwethers to small independent publishers.

We process 5+ billion impressions and handle 30+ billion bid requests every month. We're small, senior, and selective. We win by treating advertising technology as strategic infrastructure, not a plug-in.

We also believe the ad tech ecosystem can be better than it often is. We operate transparently, put our clients first, and care about whether the work we do makes the broader ecosystem healthier.

About the Role

We're hiring a Monetization Engineer to help build and operate a wide variety of ad products for our publishers, from display and video to custom implementations that solve specific publisher needs. We see ourselves as an extension of our publisher’s teams, and we're looking for someone who approaches the work the same way.

You'll write code that ships to production on websites people actually read and watch, debug live issues affecting real revenue, and contribute to the internal tools that make our team effective. JavaScript is your core day-to-day language, and you'll work heavily with Prebid, video players, and the full programmatic stack.

You should understand monetization, not just write code against a spec, and be able to think creatively about how publishers earn revenue.

What You'll Do

Your work splits across three areas:

Ad product development. Build, deploy, and maintain a range of ad products across client sites. Prebid wrappers, video players, custom integrations, experimental units, and whatever else a publisher needs. Each publisher is different, and the work reflects that.

Client partnership and problem-solving. Triage live issues like revenue drops, auction anomalies, page speed regressions, bid discrepancies, while also bringing proactive ideas to publishers. You'll join calls, scope new ideas together, and figure out what's worth building.
Internal tools. Build the tooling that makes our team more efficient: reporting, deployment automation, data pipelines, whatever unlocks leverage.

What You'll Bring

Required

• Strong JavaScript skills, including hands-on experience writing and deploying scripts to production websites
• Working knowledge of the programmatic ad ecosystem: header bidding, SSPs, ad servers, auction mechanics
• Experience with Prebid.js — you should be comfortable reading configs and debugging bid requests and responses
• Strong debugging and testing instincts; you write efficient, readable code
• Comfort building a wide variety of things. No two publisher implementations are identical, and you should be energized by that rather than frustrated by it
• Comfort with fast context-switching. Our days change constantly
• Clear written and verbal communication; you can translate technical work into plain language for publishers, ad ops teams, and non-engineers

Strongly preferred

• Python
• Experience deploying code to high-traffic production websites
• Familiarity with Google Ad Manager (GAM)

Nice to have

• Cloud infrastructure experience (AWS, GCP)
• Data warehouse experience (BigQuery especially)
• Video ad tech (VAST/VPAID, video player internals)
• Custom Prebid bid adapter development or Prebid Server experience

You don't need to have written custom Prebid adapters or be an expert in any single piece of the stack — we'll teach you the deeper internals where needed. We care more about judgment, aptitude, curiosity, and ecosystem awareness than any specific years-of-experience count.

Why This Role

Direct Impact: Senior, small team. Your work ships to production fast, directly influencing revenue and user experience on major publishers.

Meaningful Work: Build a diverse range of ad products (display, video, custom) across various publishers. We solve real, varied monetization challenges in partnership with our clients.

What We Value

These are our core operational and hiring values:

Integrity: Always tell publishers the truth about performance; don't overpromise revenue.

Transparency: Our reporting, decisions, and auction mechanics are auditable. We expect the same in internal collaboration.

Efficiency: Write fast, reliable code that respects page budget and user attention. Sloppy work impacts publisher CPMs.

Publisher-first thinking: Prioritize long-term publisher health over short-term revenue, which builds lasting client relationships.

Making the ecosystem better: We aim to build ad tech that improves the industry and seek teammates who share this goal.

This Might Not Be for You If…

You need heavy process, detailed specs, and PM hand-holding to be productive.

You want to work in a single codebase for months at a time.

You prefer work with zero client exposure.

We say this because we want to respect your time and ours. Good engineers who thrive in small-team environments will recognize themselves in this listing.

Employment & Benefits

This role begins as a contract engagement with the intent to convert to full-time based on fit and performance. We use this structure to make sure it's the right match on both sides before committing long-term.

Upon conversion to full-time: health insurance, PTO, 401(k).
