We need ambitious, experienced engineers who can help us drive this stage of growth. As an engineer at Calendly, you will both build new features and work to scale our platform and architecture. You will build tooling and automation to fine tune our delivery process as you grow into a service oriented specialist.

  • Work across squads to improve Engineering practices at Calendly and drive adoption of our shared services and components
  • Review implementation plans and pull requests from your peers and offer feedback and recommendations to ensure we’re building things in the right way
  • Mentor and coach other team members

What do we need from you?

  • 7+ years of Software Development experience at a SaaS or technology company
  • Deep understanding of distributed systems and cloud computing
  • Experience performing a major architectural refactor; bonus if you have experience refactoring a monolithic application into microservices
  • Experience building, operating, and maintaining high-traffic, high-availability platforms and systems
  • Solid understanding of secure IAM solutions, including Single Sign-On, Multi-Factor Authentication, Role-Based Access Control, and Privileged Access Management
  • Experience with identity federation solutions (e.g., using SAML, OAuth, OpenID Connect) to enable seamless authentication between different systems
  • Experience with Node, Rails, or a comparable web-app development framework
  • A drive to craft clean, reliable and maintainable code
  • Availability for participation in on-call rotation, ensuring prompt and effective responses to business-critical alerts outside of regular working hours
  • Authorized to work lawfully in the United States of America as Calendly does not engage in immigration sponsorship at this time

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
