Interview Helper — Senior Java Engineer

About the role

Part-time contract role for a senior Java engineer who wants to spend a few hours a week helping our candidates prep for technical interviews. You'll run mock interviews, give honest feedback, and occasionally sit in as a technical advisor on our intake calls. This is not a recruiting job. It's a craft job.

Responsibilities

• Run 60-minute mock technical interviews with TSH candidates (mostly Java, occasionally adjacent stacks).
• Provide written feedback the candidate can actually act on — what they nailed, what they fumbled, what they should brush up on before the real interview.
• Sit in on a small number of intake calls each month to help us assess senior-level candidates.
• Stay current enough to coach — Spring Boot, modern testing, system design at the service-architecture level.
• Occasionally help us calibrate a hiring manager's bar when we're not sure if their expectations match the rate they're offering.

Qualifications

• 8+ years of Java engineering experience, with at least 3 at senior or staff level.
• Strong fluency in Spring, JVM internals at a working level, distributed systems fundamentals.
• Genuine interest in coaching. Not every great engineer wants to do this work; we're looking for the ones who do.
• Available for 4-8 hours per week, scheduled in advance.

Nice to have

• Prior experience interviewing for FAANG or comparable rigor environments.
• Open-source contributions or technical writing we can read.
• Background in a regulated industry (extra context for our healthcare and financial services clients).
