Senior Full Stack Engineer [Remote] at Simple Habit | Powderkeg

Location: Remote

Employment Type: Full-time

Team: Engineering


We're building a new sleep product & looking for a strong generalist with extensive experience with full-stack development to join our scrappy team of 10 (3 developers).

About us:

Simple Habit, a mental wellness & meditation platform, was created in early 2016 by CEO/Founder Yunha Kim. Our mission? To help people live better. In just a couple of years, Simple Habit grew mostly organically to $5M in ARR. Shortly after, we raised $10M Series A round. In 2020, based on insights & learnings, Simple Habit decided to build & launch a new product. Our mission has stayed the same; to help people live better....but our focus has shifted to solving our users #1 wellness problem, sleep!

Did you know that almost 60% of adults suffer from insomnia? They struggle to fall asleep or sleep through the night, leading to inadequate sleep and a wide variety of negative symptoms during the day (anxiety, weight gain, irritability, depression). Sleep Reset is a "first of it's kind" wellness program that combines CBTI, content & 1:1 personalized sleep coaching to help adults sleep better, fast — without pills or side effects. And guess what? It works!


We're a fully distributed team of 15 FTE & 30 contractors, working remotely across 4 different timezones. Please note that our team works on GMT-7 PST- friendly hours, so your location will affect your work hours.

The Engineering Team & Process:

• We're a fast-moving, remote team of five developers (3 FTE, 2 Contract) from FAANG and startup backgrounds who are passionate about mental wellness and our users.

• Our engineers work directly with product, design and other stakeholders in agile processes.

• We hire passionate, generalists and as our needs change there are opportunities to work across our mobile apps, data infrastructure, backend, and automation / coach enablement tools.

• We are ultimately a product / results oriented team. Although we strive for intentional, clean architecture, we expect to make trade-offs in code quality between long-lived core service layers and rapid experimentation.

Technical Challenges:

Our talented & previously proven team is launching a new category-defining product, backed by Stanford's sleep clinic, to make lasting change for the 20% of people who struggle with chronic sleep and anxiety. For our engineering teams this requires best in-class experimentation systems and consumer web/mobile apps backed by data and recommendation services to equip our health coaches in providing efficient, personalized support.


• Technologies used today are React, nextJS, Node, Express, Mobx, and MongoDB Realm

• All new development happens in TypeScript

• Features are shipped on a daily basis

You'll thrive in this role if you're:

• Interested in an immense amount of responsibility & ownership at an early- stage startup

• Highly entrepreneurial and comfortable working in a fast-paced environment with minimal guidance

• Someone with an extreme growth mindset, driven by intense curiosity. We believe there is always room for us to improve as individual developers, a team, and a company.

• Interested in mentoring junior members and work with the team to drive improvements in our architecture, development process, and code quality.

• Excited that no day is like the other

• Nimble & passionate. We believe in ownership and expect all team members to bring technical, growth, and product ideas to the table.

Desired Qualifications...

  • 5+ years of software development experience.
  • BS degree in a STEM field.
  • Experience working at a startup.
  • Experience with React, Node.js, Typescript or equivalent.
  • Experience working with databases and ORMs. Understanding data model design, trade-offs around performance/data normalization.
  • You have technically designed and shipped features from scratch.
  • You have experience writing technical design documents, collaborating with a team of engineers, facilitating feature architecture and driving consensus.

Bonus Points

  • Experience with growth and data engineering. Passion for data and metrics.
  • Experience with contemporary API patterns, Mongo/NOSQL dbs
  • Experience working on native mobile apps and/or experience with cross-platform frameworks like React native.

Why you might be excited about joining us...

  • We’re tackling a big and common problem, sleep. We're solving it with a solution that has never been done before.
  • Current participants in our program rave about Sleep Reset. Over 80% of our users improve their sleep by week 4.
  • You’ll be able to work remotely and (mostly) set your own schedule. We've been remote for over two years and have the whole "how to work well remotely" thing down.
  • You'll have endless flexibility in your role and will be part of defining our culture, operations, infrastructure and "how we do things" at Simple Habit.
  • Everyone on the team is extremely mission-driven and works incredibly hard to push towards our lofty ambitions
  • Although Sleep Reset is new, Simple Habit is not -- this comes with many benefits.
  • (Popular opinion) Our team is incredible. Full stop. We've retained over 90% of our team through a pandemic and a product pivot! We take our culture very seriously & aim to maintain (and continue to elevate) our close-knit and supportive bond. We came for the mission, but we stay for each other.

Why you might not be excited about joining us...

  • We're an early (pre-PMF) stage start-up that recently (soft) launched in the app store. If a less established company & experimenting isn't your thing, this might not be for you.
  • We're small (10 FTE to be exact) - which means you'll not only be wearing multiple hats but you'll most likely be holding the hat of your partner and wearing their belt from time to time, too!
  • This is not the kind of job where you show up and we tell you exactly what to do everyday
  • Projects & priorities are likely to shift. And then shift again.
  • Another company's mission gets you way more fired up
  • You want a 9-5 job.
  • You do your best work in highly-structured, steady-paced, and meticulously-planned environments.
  • You should be comfortable with just a dash of chaos
  • A spontaneous dance party at our annual company holiday party doesn't get you jazzed
