Staff Engineer


Human Interest is a Y Combinator-backed company that offers an easy and affordable 401(k) retirement plan for the modern workforce. We've built an automated, paperless 401(k) that makes it possible for small and medium-sized businesses to offer a 401(k) benefit to their employees -- something that only 14% of them are able to do today. In doing so, we're empowering businesses of any size to safeguard the financial futures of their employees.

Human Interest is an equal opportunity employer. All applicants will receive consideration for employment without regard to race, color, religion, sex, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, veteran or military status, or any other characteristics protected under federal, state, or local laws.


We're looking for a highly experienced technical leader equally comfortable architecting systems, writing code, and articulating complex ideas to engineers and non-technical colleagues.

You'll work hand-in-hand with the CTO on the company's most challenging problems. This means your work will have a direct and outsized impact on the company's financial success. You'll help us accomplish something few in our industry have achieved: complete ownership of our financial back-end that will leave us poised to scale to billions of dollars under management. We can't do this without you.

In addition, you'll serve as a facilitator, strategist and set priority for all of our internal discussions around technical debt, platform, and architecture. You'll be expected to both bring your point of view and to advocate and expand on the views of our engineering team.

You'll be joining a highly collaborative engineering culture. We have an Architecture Review Board that regularly meets and discusses how to prioritize paying down technical debt. We set aside 20% of the team's time for doing this. We also love pair programming, in-depth code reviews, and documenting our work.

What you'll do

  • Contribute directly to high-impact projects of key importance to our business across the stack
  • Grow engineers in their technical skills, with a focus on senior engineers
  • Help establish and share knowledge of best practices across the team
  • Support teams in day-to-day development as a technical mentor
  • Lead prioritization of work related to technical debt and improving our platform
  • Work with engineering management to identify ways to improve our integration and delivery pipelines
  • Support engineering management in hiring junior, senior, and QA engineers
  • Learn and embrace the staggering complexity of payroll deduction-based investment and law translated to business rules!

You may be a good fit if

  • You communicate clearly and are a “wide acceptor” of many different communication styles
  • You're on the Engineer-swing of The Engineer/Manager Pendulum
  • You consider yourself a coalition-builder
  • You love making (and re-making) easily understandable and changeable code
  • You cut scope with great zeal and fairness
  • You've acted as a technical leader on teams that simultaneously paid down technical debt and shipped new features
  • You've worked as a core contributor across multiple projects simultaneously, while adapting to changing priorities
  • Other engineers you've worked with look to you as a mentor, regardless of your relative seniority

Fun problems for you to work on

  • Refine our data modeling, currently shared across SQL, GraphQL, TypeScript, Sequelize and joi
  • Research and implement industry best practices around data ingestion, ETL, task processing
  • Establish metrics and SLAs around everything we do to increase visibility and make prioritization easier across engineering and operations
  • Create observable systems so that debugging is much easier
  • Create a messaging system and figure out system boundaries
  • Research pragmatic technology choices for the above and bring your own :)

Technologies we use

  • Back-end: Node (Typescript/ES6 JavaScript, mostly) with a bit of Go
  • Front-end: React, Baobab, GraphQL, Sequelize
  • Cloud: Heroku (and a hacked buildpack for headless Chrome), Amazon S3
  • Persistence: PostgreSQL with a bit of Redis
  • Security: TweetNaCl, scrypt
  • Legacy: Tonnnnnnns of interfacing with old systems via CSVs and SFTP

Please apply if you don't match everything above!

We are more interested in talent and trajectory than qualifications or knowledge.
