What can I work on?

Alex is similar to a marketplace, as we serve both candidates through the interview experience and employers through a data aggregation and analysis platform. As a hands-on engineer, you will build both consumer-facing and enterprise-grade software with a clear opportunity for growth. Problems that you could work on related to consumer software are:

• How can we bring the average interviewer response latency down to 200ms?

• How can we fine-tune our models to decrease hallucination and help Alex pass the Turing test?

• How will our system architecture change as we scale to thousands more users, concurrently?

Problems that you could work on related to enterprise software are:

• How do we integrate with our customer’s internal hiring systems?

• What’s the best way to present interview results visually and as fast as possible?

• How can Alex expand to coordinating the hiring process end to end?

• And many, many feature requests that need to be built out!
