Revenue Vessel is a growing, venture backed software company on a mission to revolutionize how logistics companies sell. In ten months and only a pre-seed of funding, we’ve built a fully functioning product that our customers love, hundreds of thousands in ARR, and a path to grow to over a $1M in revenue by Q4 of next year.

Revenue Vessel is operating in the highly-specialized vertical of logistics, but we’re doing something totally different than other logistics software companies. While other companies sell to operations teams that have entirely unique, mission critical processes, we’re taking advantage of a key secret: **every logistics team sells roughly the same, and all of them are poorly served right now.

The three co-founders have strong backgrounds in the space: former Head of Demand Gen at Flexport, former top performing SDR manager at Flexport, former Head of Eng at Rutter API, respectively.

This could be a billion dollar business, and we don’t need to compete with other Silicon Valley founders in order to get there. We just need your help to pull it off.

**

You will be joining an engineering team of 2, both former startup veterans, as a senior technical IC. You will be given a large chunk of responsibility over the product, and as an early member of the team, you will be a key part of shaping our culture, growing the company, and building an amazing product. You will be expected to tackle projects across front end, backend, or data engineering.

**

1. You want to work closely with smart, high integrity, personal growth-oriented co-workers.
2. You enjoy working independently and quickly on things.
3. You are a product-oriented engineer who cares first and foremost about solving customer problems.
4. You are excited to take radical ownership of features and systems.
5. You love talking directly to customers, hearing their problems, and then creating a product that delights them.

**

1. You want the immediate cushy and chill life that a large, stable tech company provides.
2. You find yourself excelling in highly-structured, hoop-jumping cultures.
3. You are worried about taking on personal risk.
4. You want to move into engineering management in the next two years (we probably won’t hire a big team for a while) or build a big team around you.

**

1. be the type of person who never shies away from a problem just because you haven’t done it before.
2. Learn quickly and teach yourself new concepts as needed
3. Be familiar with our tech stack (TypeScript, Next.JS, TypeORM, React, Postgres, Heroku)
4. Be familiar with full-stack web development as well as data engineering.
5. Write solid code quickly and understand when speed trumps quality and vice versa.
6. Communicate incredibly well and proactively communicate status and priorities.

A typical week might involve building a new feature, polishing the product for a 10/10 customer experience, and scaling our systems as our user count grows.

**

The company values these things. If you’re excited about this, we’re excited about you. If these are turnoffs, we probably aren’t the right place.

1. Brutal focus: We do one thing at a time, and we do it extremely well. Right now, we’re building sales tools for logistics companies. We say no to everything else, even if someone was waving a $1M check in front of our eyes.
2. Too high integrity: We believe that integrity in business is incredibly important. We’d happily lose some money if it meant doing right by a customer or prospect.
3. Improve and Get Better Every Day: We believe in making the business and ourselves 1% better every day. As we make more money, we plan to re-invest most of it in improving our existing team as well as our processes. We give and take kind, candid feedback, and we’re always looking for ways to become better.
4. You want to build a money printing machine: We believe that at the end of the day, the only thing that matters is cash in vs cash out.

**

• Fully remote work environment with flexible hours
• Competitive comp (Strong cash, top of market equity)
• For US employees, top-tier health insurance, dental, (optional) life insurance, (optional) therapy through talkspace

**

Our interview process includes a brief coding challenge and a round of interviews focused on your technical skills and problem-solving approach. Once we’re sure you can code, we have another interview focused on culture fit.
