Role

Who you are

Deep experience (typically 8–10+ years) building and operating backend or full-stack systems in B2B SaaS, with meaningful time at Staff level or higher
Proven track record leading 0–1 products and scaling them through maturity including making and revisiting foundational architectural decisions
Strong background in distributed systems, data modeling, and API design; experience with high-traffic, high-availability platforms is a plus
Fluency in at least one of our primary stacks (e.g., Go, TypeScript/Node, React) and comfort moving across the stack where needed
Experience with modern cloud infrastructure (GCP or similar), container orchestration (Kubernetes), and relational databases like PostgreSQL; familiarity with eventing, CDC, or search platforms is a plus
Strong testing discipline (unit, integration, and end-to-end), observability (logging, metrics, tracing), and performance tuning
Experience with CRMs, marketing/sales tooling, or other data-centric systems where data quality and trust matter
Comfort working in product-led environments, where you balance speed, quality, and learning (what to build now vs. later, and how to de-risk via MVPs and experiments)
Demonstrated ability to incorporate customer signals and data into technical decisions
History of acting as an org-level technical leader - shaping strategy, influencing roadmaps, and aligning multiple teams around a coherent technical direction
Excellent written and verbal communication; comfortable bringing strong, opinionated recommendations into group settings while staying collaborative and low-ego
Experience mentoring and leveling up other engineers; you see your success through the impact of the teams around you
Availability to participate in an on-call rotation for business-critical services

What the job involves

You’ll report to an Engineering Director in Contacts and partner closely with other team leaders in driving our Contacts technical strategy
Own critical parts of our Contacts stack end-to-end, from technical design to rollout and ongoing reliability
Guide the evolution from early-stage architecture to a scalable, well-instrumented, multi-tenant system that other teams can safely build on
Lead big, cross-cutting “0–1 to 1–100” initiatives in partnership with Product, Design, and other Engineering teams
Raise the technical bar for the team through mentoring, eng leadership, and high-quality execution
Design and evolve services and data models for contacts and relationships that can support new workflows and downstream consumers
Drive decisions around our APIs, eventing, and data flows to keep Contacts a reliable system of record
Own complex, high-impact projects (e.g., new ingestion pipelines, enrichment features, or contact-centric workflows) from technical discovery through launch and iterative improvement
Break down ambiguous problem spaces into clear milestones and incremental, ship-as-you-go plans
Provide technical leadership across squads and workstreams, helping teams make good tradeoffs on performance, reliability, and complexity
Mentor senior and mid-level engineers, review design docs and PRs, and codify best practices in testing, observability, and production readiness
Collaborate with PMs and designers to translate customer problems into pragmatic solutions, especially for solopreneurs and small teams adopting CRM for the first time
Help define MVP scopes, instrumentation, and learning loops so we can move fast without compromising trust or data quality
Define and improve SLOs, error budgets, and operational playbooks for Contacts services
Participate in on-call, guide incident response, and drive durable corrective actions that reduce repeat issues

Our take

Calendly is a cloud-based scheduling service that is straightforward to use. It allows around 10 million customers per month to connect and make appointments based on their availability without having to send emails back and forth.

The platform offers four plans, allowing individuals, small companies, and large enterprises alike to make use of these services. Organic strategies have driven Calendly's growth. Its invites become links to Calendly itself, so people who like it can, and do, start to use it.

There are a handful of competing products on the market, including offerings from Doodle and Microsoft, but Calendly's customer-friendly design has won it attention and helped it to carve a space in the field. Impressive funding has contributed to the company's expansion, and its capitalised on the increasing popularity of home and hybrid working.
