Full-Stack Engineer (Consumer Product)

Principles

Self-reliance

• Don’t ask for permission - we have a constraint culture, not a permission culture.
• Own your work. Establishing your own objectives and timelines.
• Initiative is key; don't wait for tasks to be handed to you or rely solely on predefined roles. If you would like to be managed you should work somewhere else.
• Communicate directly and speak openly.

Focus

• Efficient team - we believe in the effectiveness of small, dynamic teams that can compete with, and even outperform, larger traditional teams.
• Reject waste - guard the company and your colleague's time, rather than wasting it in meetings without clear purpose/focus, or bikeshedding.

Production, speed, and excellence

• Embrace new challenges. You might be asked to do things that you've never done before. If you're not comfortable jumping into something new with no knowledge, you should work somewhere else.
• Prioritize productivity - we are developing fundamental breakthroughs. Timing markets matters which means we need to deliver. Expect to work long hours, including weekends. If you do not want to work long hours, or if you're looking for a nice easy job, this is not for you.
• Situations do not self-resolve. Unresolved problems have asymmetric risk . Focus on the long term even if it makes you unpopular now.
• Excellence. You should have an extraordinary high bar for your work.
• Obsess over the details of your work.

Responsibilities

Core contribution - develop and maintain Nosh merchant, customer, and driver mobile applications. Minimize mistakes that enter production, fix and monitor bugs, develop and design architectural standards, and introduce best practices for managing app releases.

Code reviews - maintain our high code quality standard by doing code reviews across our backend and frontend applications.

Follow best practices - build in the open with a keen focus on designing, testing, and documenting your code

Write & engage - contribute to technical reports/papers describing the system and discuss potential product improvements directly with users.

Customer support - we don't shelter engineering teams. Expect to collaborate directly with stakeholders on how best to improve the products.
