Ask HN: Who is hiring? (May 2016)

Tower Research Capital LLC is a computerized trading firm headquartered in New York City with major offices around the world. Successful electronic trading firms integrate a number of disciplines into order to be successful, including systems engineering, statistics, computer science, finance, and street smarts. Tower Research Capital LLC has assembled a team of outstanding engineers and traders who have built some of the fastest, most intelligent computer systems in the world.

Tower’s high-performance infrastructure is at the heart of what we do, and our Core Engineering team is critical to the continuing success of our business. Software plays a critical role in every part of our business: we consider ourselves a technology company as much as a trading company. The Core Engineering team performs a wide variety of functions, including designing, implementing, and optimizing our trading platform; developing systems that provide easy access to market data and trading simulations; creating tools to analyze data for patterns; and providing real-time trade support and risk management.

You can check out our jobs page for the roles we are currently hiring for.

Technologies: We use C++11 to build our trading systems and much more. Automation is mostly handled through Perl and Python scripts. But that is not a strict requirement if you can churn out good documentation :)

You can either apply to the jobs page (https://www.tower-research.com/open-positions/) directly, or email me at akshaydixi+tower at google's email service with your resume and a small blurb about yourself so I can take advantage of our generous referral programme :)

At Jvion we use machine learning and data science to help improve patient outcomes. We have our solution live in several hospital systems, and help hospitals identify patients who'll have bad outcomes. We help hospitals intervene early - and help patients avoid suffering. We recently closed a funding round, and are looking to expand aggressively.

We are looking for talented data engineers to join our team. We work with several data sources - from clinical data sources directly from hospitals, to public data sets, to socioeconomic datasets. Our data engineers help incorporate all this data into a single dataset that's used for modeling, and for real-time scoring of patients. We're looking for someone who's independent and curious, and has strong SQL skills. Knowledge of healthcare is a plus, but not necessary. We use Amazon Web Services for our entire stack, so prior experience with that would also be a plus.

Cloak is a VPN network, and a set of apps (currently for iOS and OS X) designed to connect to this service.

We are looking for a senior Android contractor to help us get our native Android app off the ground.

Right now there are just two of us developing the service. We differentiate Cloak by (1) providing a beautiful minimal UI and features like auto-secure that allow the VPN to fade into the background, (2) actually caring about the secure construction of our apps, our APIs, and our VPN network, and (3) going the extra mile, and then another, for our customers.

Our ideal candidate has:

1. Deep experience architecting complex new Android applications, and an innate understanding of the pieces that need to be put together to provide an experience that matches our current iOS and OS X apps.

2. A keen sense of how they might build and interact with OpenVPN under the app's hood, how they can implement auto-secure reliably, how they can gracefully handle captive portal networks, etc.

3. A curiosity about VPN networking, and an attention to detail to ensure that every security-critical decision the app needs to make -- from credential storage to networking configuration -- is made well.

4. Experience with modern Android development tools and practices: for example, our ideal candidate is probably running Studio beta 2.1 right now, is perhaps wary of using Fragments, already planned to start this app with appcompat, has played with or even used dagger2, retrofit and rxjava, butterknife, etc.

5. Ideally, a love of graceful UI designs, and a willingness to make pixel-detail changes or tweak animation curves when it just doesn't feel right.

This is a meaty project and we think it will be a fun challenge for the right candidate. We expect it will take real time to put together (our guesstimate is 4 full-time months, +/-1.5) We also expect we'll be working with you along the way to guide development and fill in blanks should it become necessary.

Interested? Please get in touch with me! dave[at]getcloak[dot]com
