• Provide technical leadership, mentoring, and guidance to other Two Circles engineers.

• Proficiency in monitoring application performance and health using tools like Grafana, Prometheus, Datadog, or Sentry.
• Strong passion for building performant applications.
• Proactive problem‑solving skills with pragmatic solutions.
• Excellent communication skills, able to articulate solutions to varied audiences and collaborate effectively.
• Desirable: experience building services for high‑traffic systems.

Benefits

• Hybrid working – at least 2‑3 days a week in our London office, especially during onboarding.
• Performance planning – potential salary increase every 6 months and career progression.
• Discretionary company bonus.
• Tickets to sporting events.
• Renowned Team Days and events (e.g., recent trip to Spain).

Though these are the basics, we will primarily recruit for energy, values, and commitment – both to Two Circles and to your career.

Our recruitment process will be honest and thorough, as will our roles. In return, we can offer honesty, integrity, and the chance to progress rapidly with the organization.
