Because you belong at Twilio

The Who, What, Why and Where

As Twilio redefines the market for customer engagement software, companies globally are looking to see how we do it. We have succeeded on the strength of creative programs and strict execution. But we've yet to tap the mountains of data we collect across product usage, clickstream, and ad impressions. We are excited to add a Data Scientist who will optimize the yield of over $100M in marketing investment and directly influence the story we take to market.


Twilio is looking for a Data Science professional who wants to build hypotheses and design experiments in the domain of marketing and advertising. You are eager to learn and inspire, and you like to think at scale and work with real-world problems, distilling takeaways for less-technical audiences. You should have most or all of:

  • Masters or PhD degree in Mathematics, Statistics, Computer Science or another quantitative field, or equivalent experience 
  • Strong background in statistics (design of experiments, estimation theory, hypothesis testing, time series analysis, Bayesian inference)
  • Validated experience in data mining and visualization
  • Proficiency in machine learning (supervised and unsupervised learning, reinforcement learning and multi-arm bandits)
  • 3+ years of hands-on experience with Python (preferred) or R, experience with C/C++ or Java/Scala is a plus
  • Bonus: Familiarity with distributed systems (e.g. Spark), streaming data platforms (e.g. Kafka) and Google Analytics


As a Data Scientist in Marketing, you will collaborate with marketing teams such as Demand Generation, PR, Content, and Marketing Ops. You will often collaborate with a distributed guild of other Data Scientists, embedded in their respective functions across Twilio. Key responsibilities:

  • Cultivate a POV with market trends and use anonymized Twilio product data to validate and support storylines for our PR team to pitch to journalists.
  • Optimize existing measurement tools to develop a regular cadence of reports which highlight the business impact of Twilio PR results, content and social media efforts.
  • Refine our multi-touch attribution model to understand which programs are supplying the most revenue.
  • Evaluate ground breaking ML algorithms (such as multi-arm bandit) to accelerate our time-to-insight with experiments in-market.

Twilio looks for leaders who live the Twilio Magic. For this role, it's especially important to demonstrate:

  • DRAW THE OWL: Ability to apply sophisticated math techniques in novel ways to measure the result of advertising and marketing campaigns.
  • BE AN OWNER: Ability to step up and lead cross-functional projects for which the team builds new infrastructure.
  • WRITE IT DOWN: Ability to articulate clear test plans and a business case.
  • RUTHLESS PRIORITIZATION: Ability to decide (and explain) which tests should run first.
  • EMPOWER OTHERS: Ability to build tools and frameworks that other teams in Marketing use to bring to bear insights on a go-forward basis.


Our Marketing team evaluates investments on the basis of pipe-to-spend. I.E. how much pipeline can we build for the Sales team with our budget? Every year, we not only grow our budget but also our pipe-to-spend efficiency. The better we do, the more sales reps Twilio can hire, and the faster we can redefine how the world builds software. We see potential to increase our pipe-to-spend by another 20% in 12-18 months.
