Gambit Robotics | Senior Full-Stack Engineer | NYC | Onsite | Full-time

Hi!

I’m Nicole (Ex-Google AI), cofounder of Gambit Robotics with Eliot Horowitz (cofounder/CTO MongoDB). We’re hiring a Senior Full-Stack Engineer to work directly with us in our NYC office (in-person only).

Gambit is an AI-powered kitchen assistant that mounts magnetically under most range hoods or microwaves. It uses computer vision, thermal imaging, and on-device AI to understand what’s happening in the pan in real time, and handles the hardest parts of cooking — heat, timing, and doneness — so people get better results with less stress.

You:

- 7–10 years of experience

- Strong ownership and product sense

- Thrive in fast-paced, ambiguous environments

- Experience with IoT / hardware is a plus

We’re moving quickly from prototype to product and launching at CES with a Kickstarter in January. It’s a seed-stage startup with high autonomy, real impact, and a very intense (and fun) next few months.

If you or someone you know might be a fit, email me: nicole@gambitrobotics.com

Zeno Group | Hybrid | US - NYC

Hello everyone! I’m on the lookout for an SVP of AI & Tech Operations to join my team at Zeno Group. https://www.zenogroup.com

We're a global, integrated communications agency, and one of PR Week's Best Places To Work 2025!

• I’m shaping the technology landscape at Zeno from the ground up, which means juggling everything from procurement to infrastructure to education, and need someone who can help bring order to the chaos. We have a ton of amazing and passionate people and I (still!) only have two hands.

• What you'll do is wear many hats, and so adaptability is 100% your most important attribute, along with:

- Being a diplomat between Zeno and our sister companies

- Leading AI+technology education and literacy programs

- Performing discovery for and designing workflow automation

- Convincing creatives that AI won't steal their Cannes Lions

- Exploring turning random AI experiments into useful tools

- Keeping up with AI exploration and experimentation because it’s something you do already

• You need to be comfortable building with duct tape while executives ask why it's not done yet. Agency experience helps but isn't required; what matters is you can handle 72-hour deadlines, massive egos, and the phrase "the client changed their mind."

• You also don’t buy the hype, and can cut through tech industry bullshit like a hot knife through AI slop. Being a practical cynic is a strength—you want to believe.

• If you've successfully implemented some cool AI heat at scale and can explain it to people who still print emails, let's talk.

• Hybrid role, based in NYC. Big on cultural fit. While this is not a client-facing role, some occasional face time with clients is expected.

Return | REMOTE | Software engineer backend (Go/Golang) | Full-time

Return (https://return.energy) is hiring a software engineer who will work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.

While we employ over 100 people, Return’s technical team is still small (13 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.

During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.

Your primary focus will be to further develop our battery virtualization platform that enables our customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.

Our tech stack/toolset is straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, self-hosted + cloud compute. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. Our web apps and platforms are often deployed multiple times per day.

Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very much open to working remotely as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss financials, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.

The tech team members have co-founded several companies and/or have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).
