Amplitude Analytics | San Francisco, CA (SOMA) | https://www.amplitude.com | ONSITE

We help companies build better products by providing analytics for understanding user behavior. We believe that the future of product development is in smart and easy-to-use analytics, not the complex data science stacks or surface-level vanity metrics of today. We're a 150-person company (20 engineers), and we raised our Series C last summer. We've gotten incredible traction helping customers like PayPal, IBM, Capital One, Twitter, Microsoft, and Square Enix change the way they build products.

We have many open positions that can be found here (we're growing fast!): https://www.amplitude.com/careers. In particular, we're looking to grow out the engineering team with the following positions:

* Head of Cloud Engineering

* Head of Information Technology

* Senior Software Engineer, Applications

* Senior Software Engineer, Backend

* Senior Software Engineer, DevOps

* Senior Software Engineer, Frontend

Our tech stack consists of Java, Python, Redis, Kafka, PostgreSQL, Elasticsearch, Docker, SaltStack on the backend and JavaScript, React, Flux, Highcharts, d3 on the frontend. We've got a number of extremely challenging technical problems to solve thanks to being in the analytics space, and we're looking for talented people who are passionate about the intersection of technology and product to help us take the next step.

We only hire the best engineers and pay very competitive salaries. Also, we don't do whiteboard interviews! Bring your laptop, and be prepared to write code the way you expect to on the job -- in a familiar working environment with access to the internet.

If this sounds interesting to you, please reach out to us at careers@amplitude.com or apply directly through https://www.amplitude.com/careers.

Heap (YC W13) | Software Engineer | San Francisco, CA | Fulltime | https://heapanalytics.com

Help us bring data science to the masses. We're a small team building the analytics engine that powers 6,000+ companies and helps them make smarter decisions.

Heap automates away the pain of data. Other analytics tools require you to define events upfront and manually instrument code. Instead, Heap automatically captures everything: clicks, submissions, taps, etc. This lets our users analyze data instantly and retroactively, without writing code.

We’d particularly like to get to know you if:

- you communicate with clarity and precision. We care about this almost as much as your technical ability.

- you're passionate, even if it's not about analytics. There should be something you know more about than anyone on our team.

- you’ve written 10,000 lines of code that look embarrassing in retrospect. ... and you've written 10,000 lines of good code since then.

Our app-layer stack is TypeScript, React, Node.js, Redis, and PostgreSQL.

Under the hood, Heap is powered by CoffeeScript, Scala, ZooKeeper, Kafka, and CitusDB.

If you are interested, please email at anojh@heapanalytics.com or visit https://heapanalytics.com/jobs
