Streak | Remote Only | Staff UI Engineer | https://www.streak.com/careers/staff-ui-engineer

Streak (www.streak.com) is a CRM built on Gmail. We’re a remote-first team of 35 people across North America. We’re growing and very profitable, and we have customers that love our product. We’re currently in the goldilocks zone of having product market fit with real revenue but also a really flat hierarchy where you can ship fast.

We want to accelerate product delivery (there’s so much to build!) so we’re looking to bring on high agency and experienced frontend engineers to work on high impact product features / frontend infrastructure. We’re building a small, focused, high performing frontend engineering team that works directly with the CEO leading the product. To help build this great team, we offer incredibly competitive compensation (based on Bay Area bands) and some interesting benefits(https://www.streak.com/careers#benefits). We want you to do the best work of your career here, so you should expect high autonomy and ownership.

Lastly, we believe the traditional interview process isn’t well correlated with an engineers’ ability to ship product. Instead, our interview process mimics what it’s actually like to work here. It’s highly asynchronous, favors writing and involves building something useful. We think this will give you a really good insight into our team and company and of course lets us assess if you’ll thrive here.

Stanford Research Computing | Stanford, CA (next to Palo Alto) | Full-time | Four positions | HYBRID/ONSITE

Stanford Research Computing (https://srcc.stanford.edu) is a collaboration between University IT and the Vice Provost and Dean of Research. We operate HPC environments for researchers, we do one-time consultations on projects (from software and pipelines, to data management, to physical building design and fit-out), and we provide contract support for individual Labs, Departments, and Schools.

We have three open positions:

• Research Computing Manager: Our current IC:Manager ratio is 7, which is too high, so we're hiring another manager for our group! You'll oversee a number of ICs, help them plan & prioritize their work, make policy decisions, and contribute to Research Computing's strategic direction. You'll also be interacting with groups throughout the University, as a service provider and as a policy maker. More info: http://phxc1b.rfer.us/stanford0_zslt

• Research Storage Consultant: We have lots of storage environments (both on-prem & cloud); it can be confusing to identify which is the best for a given purpose, and how to take full advantage of it. Your job will be to help Students & Faculty figure out what storage is best to use, and get them started on using it! More info: http://phxc1b.rfer.us/stanfordwvasls

• Data Center Engineer: We hired a Data Center Engineer nt too long ago, You'll be based full-time at our primary research data center in Menlo Park (on the SLAC campus). This position includes everything from racking and cabling to maintaining and troubleshooting power distribution (415v Starline bus), UPS (spinning-mass), generators, VFDs, air handlers, chillers, PLCs, and the like. More info: http://phxc1b.rfer.us/stanfordhrmslu

(For those curious: Yes, we did hire a Data Center Engineer recently, but this posting is different: One of our existing Engineers was prompted to Data Center Director, causing a new Engineer position to open up!)

The data center position is onsite; the others are hybrid. If you don't already live in the Bay Area, we provide a relocation incentive. Depending on where you live, we provide free transit passes. Unfortunately, if you don't commute, you will have to pay for parking for the days you're on-site (except at the data center). There is some on-call around the holidays. We get a 403(b) match, good healthcare, and 30+ days off per year (holidays + vacation). All Benefits are all publicly documented at https://cardinalatwork.stanford.edu/benefits-rewards. If you have questions, feel free to reply here or email me (the info is in my profile)!

Syntasso | Product Engineer | Hybrid in London, UK

Hey HN! We’re Syntasso, a startup empowering platform engineering teams to thrive. Our flagship open-source project, Kratix, helps companies build and manage internal platforms without reinventing the wheel.

Why Join Us?

- Shape the Future: Be part of a fast-growing open-source project that's already making waves in the platform engineering space.

- Grow Your Skills: Our founders are industry leaders who speak at DevOps Days, KCD, and more—you’ll get to learn from some of the best in the biz.

Cargado | (Senior) Software Engineer, Founding Data (Analytics) Engineer | REMOTE (US) | Full-time

What do we do?

- Cargado is an early stage technology startup revolutionizing how U.S.-Mexico cross-border logistics is executed. So far, we’ve focused on helping brokers with freight find the carriers best suited to haul that freight. Read more about our current products here - https://www.freightwaves.com/news/exclusive-cargado-launches...

Why are we going to 100x?

- The TAM here is massive. Mexico has recently taken over the #1 spot as the United States’ leading trading partner. Laredo, TX is the number one port in the United States importing and exporting everything we need and use everyday. We’re going after that with an incredible team that brings a unique blend of tech experience (Amazon, Google, Microsoft) and freight experience (Convoy, Coyoted, Flexport, and more). Just check out our founders, Matt (https://www.linkedin.com/in/mattpsilver/) and Rylan (https://www.linkedin.com/in/rylanhawkins/).

Freight seems boring though. Why would I want to build software with Cargado?

- This is an industry starved for technological innovation. We’re solving problems that have never been solved before and have the opportunity to create massive impact for individuals and the world at large, since any efficiency gain can be huge when you’re talking about driving around an empty tractor trailer at 8 mpg. Additionally, we’re committed to building world-class technology and invest in learning, dev ex, and planning/design to make that happen.

Sure, but it takes money to make money. How will you survive long enough to change the world?

- We’ve raised nearly $10M in venture capital so far (from Ironspring, Primary, Zenda, Wischoff, and more), and before even hitting 1 year we’ve achieved strong revenue from a customer base of over 100 brokers. Taken together, that means we have a diversified source of income in addition to a strong balance sheet.

Our tech stack includes: Typescript, React, NextJS, PostgreSQL, AWS
