Role Overview You'll design, build, and ship the core systems behind mate: the pixel, tracking, and ad delivery services that brands plug into and rely on every day. If you've built production systems inside a DSP, an ad platform, or an ad tech company and know how pixels and conversions actually work under the hood, this is a senior seat where you'll own real architecture decisions on a small team that ships fast.
Please note: this role is a US-based role only and we cannot offer visa sponsorship for this role at this time.What You'll Do Build and ship core product- Design, build, and ship backend services and APIs that power mate's agents, from spec to production
- Improve and maintain an identity graph.
- Own features end to end, partnering with product and design on what to build and how
- Write clean, well-tested, production-grade code and set the standard for the rest of the team
Ad tech infrastructure- Build and maintain our pixel, tags, and server-side tracking, and the conversion integrations with Meta, TikTok, Google, and others
- Build integrations with DSPs, ad platforms, and partner APIs
- Build the real-time services that deliver offers across the network, fast and reliably
Architecture and reliability- Make architecture calls on how our systems scale: service design, storage, queues, and caching
- Own reliability in production: monitoring, alerting, debugging, and incident response
- Improve developer tooling, CI/CD, and pay down tech debt where it slows us down
Engineering leadership- Lead design reviews and code reviews, and mentor other engineers
- Help shape engineering practices and hiring as the team grows
RequirementsWho You Are- You've built ad tech from the inside and know how the pieces connect, from pixel to conversion.
- You like owning a system end to end, not just a ticket queue.
- You're pragmatic: you ship fast on a small team without cutting corners on quality.
- You think about the brand's outcome, not just whether the code ships.
- You raise the bar for the engineers around you.
What You Bring - 6+ years building and shipping production software, with meaningful time at an ad tech company (DSP, ad platform, ad exchange, or identity provider)
- Strong backend engineering skills in Python and Typescript, including designing APIs and distributed services
- Hands-on experience building pixels, tags, SDKs, or conversion tracking, client-side and server-side
- Experience building systems that handle high request volume with low latency
- Comfort with cloud infrastructure, containers, and CI/CD
- A track record of owning systems in production, from launch through monitoring and on-call
Bonus: Identity resolution / graph networks, ecommerce or Shopify, or early-stage startup experience.
Why This Role MattersMate only works if the systems underneath them are fast, reliable, and plugged into the ad platforms brands already buy on. This engineer builds that foundation. Get it right and brands see clearer results, buy more effectively, and spend more with us. It's one of the highest-leverage engineering seats at the company
