• Continuously improve system performance, reliability, and developer experience

- 6+ years of professional software engineering experience

- Strong foundation in programming and software design principles

- Proven experience building well-scoped, performant modern web applications

- Production experience with React or Next.js and at least one of the following languages: Go, Python, or JavaScript

- Comfort navigating the full stack and pulling in what's needed to ship

- Strong ownership mindset and ability to work effectively within cross-functional teams

- Search infrastructure experience (Elasticsearch or similar)

- Familiarity with message brokers (e.g., Kafka, RabbitMQ, AWS SQS)

- Builds strong partnerships with engineers, product and design, contributing to team and organizational growth

• Proactively surfaces problems and drives them to resolution

- Competitive compensation: base salary $200,000 ~ $220,000 + stock options

- Home office setup stipend
