About our customer
Over 1.5 million customers and more than a billion people in over 180 countries use our customer solutions to accelerate the process of doing business and simplify people’s lives. With intelligent agreement management, our client unleashes business-critical data that is trapped inside of documents. Until now, these were disconnected from business systems of record, costing businesses time, money, and opportunity. Using the customer's product companies can create, commit, and manage agreements.
Team Overview
The unified, widget‑based front-end platform that powers Intelligent Agreement Management (IAM) experiences across creation, sending, signing, and management—bringing consistent, modern UX to our most visible product surfaces. It standardizes how teams build UI via a shared shell and micro‑frontend architecture, with robust utilities and CI/CD that publish versioned widgets to our global CDN for reliable, high‑scale delivery. Engineers on our Team work at a meaningful scale—building experiences used by 1.7 million organizations—and integrate agreement‑centric AI to turn contracts into intelligent workflows. Joining our Team means shaping platform patterns, performance, and observability that accelerate how online signature works across the company.
The product also enable federal‑grade workloads without sacrificing developer velocity. Engineers here tackle secure‑by‑default patterns for identity, data handling, and observability—building on zero‑trust principles, strict network segmentation. You’ll design for high availability in constrained environments, optimize performance with privacy, and leverage automated compliance guardrails in CI/CD to ship with confidence. If you enjoy solving hard platform problems—telemetry without PII, resilient rollouts, deterministic builds, and least‑privilege runtime sandboxes.
