About the Role

Junior is building the AI operating system for investment research, helping financial institutions complete research workflows faster. The company is bootstrapped, profitable, and growing rapidly. This role will report to the CTO and own the day-to-day operation of engineering, including people, planning, delivery, reliability, and recruiting, while remaining deeply technical and close to the code.

Responsibilities

  • Own the day-to-day operation of engineering: people, planning, delivery, reliability and recruiting.
  • Turn product and technology direction into results.
  • Challenge scope, sequencing and commitments when they aren’t credible.
  • Make sure the organization delivers on its commitments.
  • Ship production code.
  • Learn our systems and development tools.
  • Join architecture and debugging discussions.
  • Work directly with engineers, Product and customers.
  • Take an on-call shift.
  • Build firsthand context before changing how the organization operates.
  • Develop hands-on Engineering Leads who can run strong, autonomous teams.
  • Build a lean organization capable of growing toward 40–60 engineers.
  • Own engineering hiring and help maintain a very high technical bar.
  • Lead feedback, performance and development.
  • Give excellent ICs room to grow without becoming managers.
  • Establish clear ownership of critical systems.
  • Improve incident response and eliminate recurring failures.
  • Remove friction across tooling, testing, reviews and delivery.
  • Turn AI-assisted engineering into measurable improvements in speed and quality.
  • Own engineering’s infrastructure, tooling and AI spend.
  • Be accountable for the value received from engineering spend.
  • Introduce structure where it helps us move faster and remove it when it doesn’t.

Requirements

  • Still deeply technical and can write production code, understand unfamiliar systems and debug difficult problems.
  • Led engineering teams through meaningful growth and ambiguity.
  • Can point to specific improvements made across delivery, reliability and organizational clarity.
  • Hired excellent engineers and developed strong ICs and engineering leaders.
  • Comfortable giving difficult feedback and making performance decisions.
  • Knows when management and process help and when they get in the way.
  • Built software where reliability, security and customer trust genuinely matter.
  • Uses AI development tools thoughtfully and has strong views on how they will change engineering teams.
  • Can challenge a highly technical founder constructively.
  • Wants to work closely with Product, customers and the codebase.
  • Prior VP or Head of Engineering experience is not required.

About the Company

  • Junior is building the AI operating system for investment research.
  • Our software helps private equity firms, consultants and financial institutions complete high-stakes research workflows dramatically faster.
  • We’re building toward a future where AI can run substantially more of that work: conducting research, understanding evidence and producing outputs customers can use to make decisions.
  • Bootstrapped and profitable
  • ~$28M+ ARR, after growing 10x last year
  • 65+ people across New York, London and Sydney
  • ~20-person engineering team across four to five teams
  • Trusted by leading private equity firms, consultancies and financial institutions.
  • Core stack: TypeScript, Next.js and PostgreSQL
  • AI-assisted development has already changed how quickly we can build.
  • Our current engineering team operates with the output of a much larger organization — and that pace is only increasing.
  • We’re now looking for someone to build the engineering organization for Junior’s next chapter.
