Industry UsageCommon in consulting, freelance, or specialized project rolesWidely used across manufacturing, automotive, aerospace, and industrial sectors

The main difference between a Sole Engineer and a Mechanical Engineer lies in scope and work style. Sole Engineers often operate independently on specific tasks or projects, while Mechanical Engineers typically work within teams on larger, more complex engineering projects. Both roles require relevant engineering credentials, but their work environments and industry applications differ.

What is a sole engineer?

A sole engineer is a professional responsible for managing engineering tasks independently within a project or organization, often handling design, development, and troubleshooting without a team. This role requires strong technical skills, problem-solving abilities, and often involves working in small teams or solo environments. Certifications like Professional Engineer (PE) may be beneficial, and the position typically demands self-reliance and comprehensive technical knowledge.

Full-time

Job description

Upside is a referral partnership platform for professional services. We're enabling the future of work where most knowledge workers do some form of consulting or advising - either full-time or on the side. 82% of knowledge workers want to diversify their work outside of a single employer, but only 1 in 3 who want in are doing it. Most people do not want to market their own services publicly or become Linkedin thought leaders. Upside solves this by enabling people to privately get clients from their network and earn money by making referrals to others.
Our founding team are repeat founders and alums of Y Combinator, Amazon, and Venture for America. We've built freelance marketplaces, tools, and professional networks before, and our past companies have been backed by investors like Khosla Ventures, SV Angel, and Bloomberg Beta. Upside builds on everything we've learned over the course of our careers so far.
With Upside we're taking a different approach from traditional freelance and professional networks. We're building the bottoms-up SaaS that helps people power their own referral networks. We're in paid private beta with a user base that's growing significantly month over month, with multiple case studies of users making 6-figures in net new income via Upside.
We're now looking for our founding engineer to help us build the product that can support and continue to drive our early growth. Ideal candidates have a founder mentality and strong ownership. You're often the first to roll up your sleeves and get into the trenches to solve a problem, and have a strong bias for throughput. While you love engineering, you're driven first and foremost by serving and shipping valuable stuff for customers. Maybe you've built and scaled products from scratch before, or maybe you're itching to take on that challenge for the first time.
Why you might be excited about us:
  • Our founding team has all worked together before, and we have a great operating rhythm for someone new to plug into
  • Our customers are impressive people who are a joy to work with and learn from
  • You'll have a lot of flexibility in your role and will be able to help define what it looks like and where you want to go over time
  • You'll be the fourth person on our team and will get deep exposure to every part of the business
  • We're firmly committed to in-person (3 days/wk in our Lower Manhattan office). We believe IRL collaboration is essential in the early stages of company-building.

Why you might not be excited about us:
  • We're small, so if you like more established companies, this role isn't for you. You'll help create our company's culture.
  • You should be comfortable with ambiguity. This is not the kind of job where you show up and we tell you exactly what to do every day.

Ideal candidates have the following qualities:
  • Strong full-stack web development experience
  • Relish the opportunity to be the sole engineer and work with our product lead to build tech from scratch, quickly
  • Good product instincts and interest in contributing to the growth of Upside beyond just engineering
  • Familiarity with the problem we're solving, including doing some form of consulting/freelancing/contracting in the past
  • 4-10+ years professional experience
  • Based in NYC (or willing to relocate)

Our values
  • Be positive sum, not extractive
  • Align incentives, don't rely on good intentions
  • Humbly serve our customers and learn from them
  • Be high-throughput and build leverage as we go
  • Enable upward mobility for ourselves and others
  • People invest things other than money so treat everyone like an investor

Compensation
$150,000 - $200,000 + equity
