Worldwide: https://www.doubleverify.com/careers/?gh_src=221704c02

DoubleVerify improves the impression quality and audience impact of digital advertising. We ensure ad viewability, brand safety, and fraud protection for hundreds of Fortune 500 companies.

My team in Belgium optimizes hundreds of thousands of video ads per minute. We also do a fair amount of data science. We're a full-stack JavaScript team, but we focus on computer science fundamentals rather than specific tech. In fact, many of our top engineers started out without any JavaScript experience!

If Belgium's not your thing, we're also hiring talented engineers at our offices in New York and Tel Aviv.

Kalepa | Backend / Data Engineers | Full-Stack Software Engineers | Machine Learning Engineers | Lead Product Designer | New York City, NY | ONSITE / PARTIAL REMOTE, VISA

Kalepa is a New York based, VC backed, startup building software to transform and disrupt the $1T commercial insurance market.

Engineers and designers at Kalepa are solving interesting and challenging problems at the intersection of big data pipelines, cutting-edge machine learning models, intuitive frontend apps, and robust infrastructure. You will be working in a small team building technology from the ground up with the latest stack.

One trillion dollars are spent globally each year on commercial insurance. However, the process for estimating the risk associated with a given business across various perils is still reliant on inefficient and inaccurate forms and research. This information asymmetry leads to a broken set of incentives and a poor experience for both businesses and insurers alike. By combining cutting edge data science, enterprise software, and insurance expertise, Kalepa is delivering precision underwriting at scale. Kalepa is turning real-world data into a complete understanding of risk.

Kalepa's team members have worked at Facebook, Google, Microsoft, ClassPass, APT (acquired by Mastercard for $600M in 2015), Wonder, the Israel Defense Forces, MIT, Berkeley, and UPenn. We are backed by IA Ventures.

Y Combinator | Product Engineer, Startup School | SF, CA | Full-time | On-site | https://jobs.lever.co/ycombinator/ef091f3d-df02-433c-a6c0-7b...

Y Combinator started Startup School two years ago as a way to help as many startups and founders as possible. Over 30,000 companies and 40,000 founders participated in 2019 — our largest cohort ever. We are looking to scale Startup School's impact even further by hiring a product engineer on our small YC software team.

In this role, you will:

- Design and build out new features, including video office hours, AMAs, event planning, forums and more

- Scope and prioritize items on the Startup School roadmap alongside YC partners and others on the team

- Analyze usage and engagement with an eye for improving the participant experience

- Learn a ton about startups: from technology to business to fundraising to growth and everything in between

We're looking for capable generalist engineers. We care mostly about your ability to write great software; we don't care if you've used the technologies we work with as long as you're willing to learn them. Because we don't have product managers, we look for engineers with great product instincts who can own whole projects from start to finish.

This is a good job for someone who is excited about startups and interested in learning more about them. You've likely worked at or started a startup, or want to do so in the future. Also, the team has a lot of individual responsibility and access to sensitive information, so we need to hire people we can trust. Your ability to make good trade-offs and exercise good judgement is particularly important to us.

Benefits: In addition to top quality healthcare benefits, offerings include 401k matching, generous parental leave, commuter benefits, catered lunch, and a flexible vacation policy. We also offer highly competitive compensation, including equity in YC.
