Job description

You’ll play a critical role in helping customers and prospects succeed with Glyphic. From early sales conversations through onboarding and long‑term usage, by acting as a technical partner, problem solver, and advocate.

Sitting at the intersection of customers, product, and engineering, you’ll work hands‑on with real customer environments and production systems. You’ll help unblock technical questions early in the sales process, ensure customers onboard smoothly, and turn real‑world customer challenges into scalable product and platform improvements as Glyphic grows.

In practice, this means you will:

Partner with Sales on calls to advocate for Glyphic, validate technical requirements, and answer in‑depth technical questions before customers buy.

Work closely with Product and Engineering to surface patterns from customer work, helping prioritise features and shape the roadmap based on real customer needs.

Triage and resolve technically complex customer issues across integrations, APIs, data flows, and workflows.

Support customers transitioning data, workflows, and processes from competitors or legacy tools into Glyphic.

Handle bespoke customer data requests, balancing speed for the customer with scalable, reusable solutions.

This role exists to ensure customer learnings flow directly into the product, integrations scale cleanly across accounts, and engineering time is spent building the right things, not firefighting.

Your profile

You’re a customer‑facing engineer who enjoys working on real‑world systems and solving practical problems end to end. You’re comfortable switching between debugging production issues, writing code, and working directly with customers to unblock them.

You bring a strong technical foundation, paired with empathy for users and a bias toward building scalable solutions rather than one‑off fixes.

You likely have:

Experience writing production‑quality code, scripts, or internal tools.

Hands‑on experience working with APIs, integrations, and data flows.

Strong debugging skills across multiple systems and layers.

Experience working directly with customers or users in a technical context.

Comfort owning problems end to end in an early‑stage or fast‑moving environment.

You might also have:

Experience integrating with CRMs or third‑party SaaS tools (e.g. HubSpot, Salesforce).

Exposure to customer onboarding, implementations, or POCs.

Experience building internal tooling, automation, or monitoring.

Interest in shaping product direction based on real customer usage.

Above all, you’re a builder with empathy, you care about solving the right problems, not just shipping code.
