Ask HN: Who is hiring? (May 2017)

Amazon Web Services | SDE / SysDE / Research/Data Scientist | Seattle, Palo Alto (ONSITE) | VISA, aws.amazon.com, AS16509

The Internet is the world’s most complex network, with over 57,402 unique networks connected together, it contains hundreds of millions of edges and nodes. It is THE most pervasive, important, and complicated communications network in the world -- somewhere out there things are about to go south. One of the core backbone routers of a major Tier-1 Internet provider is having a bad day. It started with a transient, yet persistent, problem which was only detectable by a slight increase in dropped packets that went mostly unnoticed. An hour later the router suffered a catastrophic failure dumping 500Gbps of traffic onto an already congested alternate path causing ripples across the Internet, disrupting websites and other Internet based services on the U.S Eastern seaboard. Social media is ablaze as frustrated people rant about their favorite website, video, or gaming service being down, or so slow that it’s unusable. While the Internet burns, our customers are humming away oblivious to the disaster. If you have an insatiable curiosity, love the process of discovery, and you’re reading this with a grin... we should talk. Come join us and...

* Do what nobody else in the world is doing... literally.

* Gain knowledge and expertise on the inner workings of the Internet, working with top-tier Network Engineers

* Define and Develop Amazon’s Internet Monitoring architecture

* Play in the piles of data to discover patterns that push our understanding and knowledge of Internet performance and availability anomalies

* Build massive real-time systems which inform and drive complex changes across the Internet

* Gain practical experience building software using Amazon Web Services

We are hiring for SDE/SysDE I (Entry Level), SDE/SysDE II (Mid-Level), Senior SDE, and Research/Data Scientist I/II (Entry/Mid Level). We may have an opening for a Data Engineer I/II in the future.

10x Genomics | Software Engineer | SF & Pleasanton, CA | Onsite, 10xgenomics.com

We're a biotech company developing novel software, chemical, and microfluidic systems to allow better understanding of biology and our genomes. We're looking to grow our software team of currently six engineers (including myself) to support the rapid adoption of our technology. We've seen a growing number of high profile publications that use our technology (https://www.10xgenomics.com/publications/).

Recently, the team that works on Supernova, our in-house de novo genome assembler, published a paper on a new push button algorithm that allows determination of the human diploid genome from about 1ng of high molecular weight DNA! [1] Typically, researchers still use a haploid representation of the genome and previously only two other true diploid de novo human genomes have been made.

You can also read about (and run if you'd like) our massively parallel pipelines at https://support.10xgenomics.com/. We manage our pipelines with Go, develop analysis code using the NumPy stack, and drive our front-end applications with React/Redux (previously Angular 1), but we're always open to any technology that allows us to develop faster. No previous biological experience is required; we have plenty of computational biologists here to handle that, but there is a lot to learn about if you're curious. You'll work with a group of humble engineers that are alums of YC, MIT, Harvard, Caltech, Google, Facebook, and more.

We're currently hiring for several software roles, but specifically for generalists, UI engineers, QA engineers, and infrastructure engineers. Our computational biology group is also always looking for bioinformaticians who are experienced with NGS, and our company is always looking for scientists and engineers (hardware included). Here are some of the job postings we have up, but feel free to email me if you think you're a good fit for another role.

- UI Engineer - http://www.10xgenomics.com/careers/274522/ - Linux / Infrastructure Engineer - https://www.10xgenomics.com/careers/537730/ - Software Quality Engineer - http://www.10xgenomics.com/careers/476114/ - Software Quality Engineer (Computational Biology) - http://www.10xgenomics.com/careers/472908/ - IT Support Engineer - https://www.10xgenomics.com/careers/625410/

Just a note that we do have an office in San Francisco even though the listings only specify Pleasanton. Our full page of job listings can be found at http://www.10xgenomics.com/careers/. Reach out if you're interested in working on high impact, genomic-ly big data problems using modern software development best practices or even if you just want to chat. You can reach me at kevin.wu@10xgenomics.com or @kevinwuhoo.
