You’ll be one of the first engineers on the team and help bring our first product to market. You’ll work closely with the (technical) CEO and teammates on engineering, design, growth and go-to-market to prioritize the product and tech roadmap; you’ll also be a critical part of the engineering team responsible for building and shipping.

  • A strategic thinker who can plan & reason about product, technology, processes, and people
  • Ability to execute in a remote startup environment
  • Curiosity, humility, a desire to learn and grow and to help others learn and grow
  • Passion for building thoughtful, ethical technology
  • Experience with the current tech stack

Nice-to-haves, but not required

  • Experience at an early stage startup
  • Experience as a tech lead or engineering manager
  • Experience at a consumer social platform company or working with their APIs
  • Experience with trust and safety / moderation / anti-abuse

Tech stack

Our web UI is built in React.js, Jinja, and SCSS, and served by Python Flask through a GraphQL API. The bulk of the engineering work is in systems to fetch and process large amounts of data, e.g. from the Twitter API; we use Celery for this asynchronous task work. The persistent layer is backed by PostgreSQL with SQLAlchemy/Alembic as the ORM. We use staging environments and CI to ensure we continue to deliver a consistent user experience. We are hosted on Render and AWS.

Diversity and inclusion

At Block Party, we believe in diversity and inclusion, and no applicant will face discrimination based on: race, ethnicity, national origin, religion, age, gender, sexual orientation, gender identity, disability status, parental status, or veteran status.
