About the role

  • This is a full stack role where you'll work across a Python/Flask API, a React frontend, and the data pipelines and integrations that connect them.
  • You'll hit the ground running on a production system with real customers, shipping work that compounds in impact over time.
  • The engineers who thrive here are the ones who can look at a mature codebase, see the path to making it better, and execute without needing to rewrite everything first.

Responsibilities

  • Own features end-to-end: from API design and database migrations through React UI and data visualization, all the way to monitoring and on-call support
  • Build and harden integrations with third-party ad platforms (Meta, Google, TikTok) - design for reliability across APIs you don't control
  • Design and build data-rich UIs: charts, dashboards, and interactive tools that help marketers understand complex experimental results
  • Haus is the incrementality platform leading brands trust to optimize billions in ad spend worldwide.
  • With a founding team of former product managers, economists, and engineers from Google, Netflix, Meta, and Amazon, we make high-quality decision science, incrementality testing, and causal marketing mix modeling accessible to businesses of all sizes-automating the heavy lifting of experiment design, data processing, and insights generation.
  • Haus is well-capitalized and backed by top-tier VCs, including Insight Partners, Baseline Ventures, Haystack, and others.
  • You'll build and evolve the systems that power how the world's leading brands understand the true impact of their marketing spend.
  • Our platform runs geo-based experiments, integrates with major ad platforms (Meta, Google, TikTok), and delivers causal inference results that directly drive budget decisions worth millions of dollars.
  • We're looking for someone who's excited about this way of working and wants to push the boundary of what a small, high-output engineering team can deliver.
  • If you thrive in ambiguity, take pride in raising the bar, and want to work alongside top-tier peers who challenge and support you, you'll find unmatched opportunities here.

Requirements

  • 8+ years of experience building and shipping production web applications and APIs
  • Excellent communication skills - you can explain technical tradeoffs clearly and work effectively with scientists, product managers, and other engineers
  • Experience with ad platform APIs (Meta Marketing API, Google Ads API)
  • Experience with data visualization or experimentation platforms - if you've built charts that help people understand data or worked on systems that run experiments, you'll ramp faster here
  • Experience with third-party data integrations and ETL workflows

Nice to have

  • Proficiency in Python and React (or strong equivalents with willingness to ramp)
  • experience with Flask, SQLAlchemy, or similar frameworks is a plus
  • Experience working in and improving large, established codebases - you've navigated legacy systems, made pragmatic tradeoffs between refactoring and shipping, and left things better than you found them
  • Experience with relational databases (MySQL/PostgreSQL) and data-heavy applications
  • Comfort with cloud-native environments (GCP preferred): you understand how to deploy, monitor, and operate services in production

Compensation

  • Over $360B is spent annually on paid advertising in the US alone, and the famous quote "half the money I spend on advertising is wasted; the trouble is I don't know which half" still rings true.

Benefits

  • Some of our benefits include:
  • Flexible PTO - take time when you need it!
  • Equity - Startup environment with part-ownership in our successes
  • Top of the line health, dental, and vision insurance - multiple plan options so you can pick what fits you best
  • WFH stipend to support the set up you need to be productive
  • New Parent Leave - take time to welcome your newest Hausmate
  • We make hiring decisions without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected status.

Company info

  • Evolve and modernize a production Flask + React application that serves hundreds of customers - improve architecture incrementally while shipping continuously
  • We care deeply about our customers and expect everyone to take full ownership of their work - this is a place where high expectations fuel even higher growth.
  • Use AI development tools as part of your daily workflow to accelerate delivery, explore solutions, and raise the ceiling on what you can ship
