Principal Software Engineer
Shiftsmart Inc
Join Shiftsmart
We're building the Amazon of labor. We're a labor platform pairing end-to-end workforce management technology with a rapidly growing global network of 5M flexible workers to create scalable labor solutions for the largest companies in the world, like Circle K, Pepsi, Dollar General, Starbucks and more. Our unique business model fractionalizes jobs down to shifts and makes it easy for workers to work across multiple companies through a digital marketplace. We're one of the fastest-growing startups in the country. We've grown 2-3x each year since we started and raised $120M+ from top-tier investors including D1 Capital & Imaginary Ventures …and we're only getting started.
Our mission is to build the world's leading platform for hourly workers and enterprises enabling flexibility, choice, and upward social mobility.
Join a rocketship. This is a unique opportunity to join the ground floor of a rapidly scaling business that is changing the way hourly labor works and capturing a $2 trillion dollar opportunity in the US alone.
Ownership + impact. Join a team that is challenging and supporting one another to build a great business and create flexibility, choice, and upward social mobility for workers everywhere.
Captain your career path. Enjoy accelerated learning and growth working with a world-class team from top tech companies (e.g. Uber, Airbnb, Google, Amazon), business schools (e.g. HBS, GSB, Wharton), and professional services (e.g. Bain, BCG, Goldman).
Become a world-class executor. We believe that #ExecutionIsBinary, and are dedicated to helping you master that skill for life here and beyond.
Mission: Why This Role Exists
The Engineering Team enables Shiftsmart to anticipate and creatively solve problems across multiple functions with solutions that have a lasting impact for both our customers and our users. Our mission is simple: To build the world's leading platform for hourly workers and enterprises enabling flexibility, choice, and upward social mobility.
This role is based in New York City (HQ) with typically 3+ days per week in the office.
Outcomes: The Problems You Will Solve
As a core member of our rockstar engineering team you will;
- Lead complex technical projects from ideation and design through production and deployment, for example, tune the dispatch algorithm to drive shift fill rate improvements, build better onboarding experiences to increase worker conversion, and more
- Design, architect, and build highly-performant and reliable technical features, tools, and services using Node.js, React/React Native, Mongo, Python, GCP
- Drive the technical vision, influence product strategy, and conduct regular technical reviews
- Monitor and maintain the performance of our product and platform in a high user volume, two-sided marketplace environment to resolve issues and clear the shift marketplace
- Serve as a mentor for junior engineers and participate in scaling our team
Competencies: Who You Are
- A software expert: You have 7+ years of software engineering experience. You have a core competency in Javascript, Typescript, or Python and enjoy learning about and using new technologies
- A collaborator and teammate: You enjoy working cross-functionally with leadership, PMs, designers, and other engineers to build products across a modern tech stack (MERN) to solve complex problems
- Outcome oriented: You seek to understand the business context and how your technical work translates into real-world business outcomes
- Builder: You are an entrepreneur at heart, you create clarity in ambiguity, and take initiative to own the outcome without waiting to be told
- Startup Hungry: You are eager to work in a dynamic and fast-paced early-stage startup, and have the ability to roll up your sleeves to #GetShiftDone

Operating Principles @ Shiftsmart
Inspired by Leadership Principles @ Amazon
Execution Is Binary
We #GetShiftDone. We take immense pride in both the quality of our work and our relentless determination to deliver on our commitments. If we say we are going to do something, we do it.
We own the outcome with an unstoppable mindset through the finish line and are impatient to move the ball forward. This means we work really hard, execute with urgency, and ruthlessly challenge timelines for anything important. As a result, we do not defer responsibility to other teams or individuals. Instead, we take the problem as far as we can and only when needed ask others for help.
Each time a crisis or opportunity emerges we take the hill as one team, because we are allergic to the words "it can't be done".
Missionaries, Not Mercenaries
We before me. We believe in our mission to build a better world for workers. We understand why our work matters and take seriously how it impacts our customers and our partners. This belief permeates everything we do from the strategic to the mundane.
We are energetic, ambitious, and want to win. We constantly raise the standards for ourselves and everyone around us. We show up for our customers, our partners, and most importantly our teammates, and make every effort to build lasting relationships with each of them.
We do not measure success based on our titles or the size of our empires. This also means we put the needs of the business before the details of our job descriptions. Rather than fight for a bigger piece of the pie, we fight to grow the entire thing and recognize this is how to grow our careers too.
Inputs > Outcomes
We work really hard. Fundamentally changing how labor works is not easy. It often requires long days, late nights, and weekends to deliver on our commitments. We lean into this challenge.
We focus on the process. We think in terms of value chains and appreciate that a bad process with a good outcome is simply dumb luck.
We lead with data. We use facts, not fiction, to build narratives and make decisions. To do this we prepare written memos in advance and resist the urge to engage in endless water cooler what ifs, because we value the time and attention of our teammates.
We hire and develop the best. When we decide to hire a new team member, we do so because we believe they will increase the talent density on our team. We view ourselves as leverage maximizers rather than inconvenience reducers and strive to increase the output of everyone we interact with.
Honesty Over Harmony
We share the truth even when it is painful. We do not, however, share the truth callously to hurt people's feelings or make them look bad. We also assume positive intent. If someone is not delivering in a way that we need, we ask them and tell them before assuming the worst.
We embrace mutual feedback. As people leaders we care more about our team's growth and success than how much others like us. As individuals we seek, accept, and apply feedback. We do not give or take feedback personally because we understand it enables us to learn and grow.
We tell the truth to ourselves. We reject a pollyannaish view of our world. Instead if something isn't going well that we are responsible for, we call it out. And when someone calls out their own truth that may be less optimal, we don't punish them for it.
