Customer Success Engineer - America

Position description

We're launching Customer Success Engineering — a brand-new function at Sonar, built from Austin Tx. As a founding CSE, you'll help write the playbook. We are proactive technical advisors who own the health, maturity, and growth of a customer portfolio — with AI at the core of how we operate, keeping a pulse on every account so we focus our energy where it creates the most impact. CSE is not support, not services, and not a sales overlay. It's a strategic role for engineers who love technology and business impact in equal measure — and who want to redefine what customer success looks like.

What You'll Do:

• Own a portfolio: be the trusted technical advisor for your accounts across the full journey — onboarding, adoption, health, value realization.
• Act on signals: AI surfaces the risks and opportunities across your accounts; you take them from signal to outcome — accelerating growth, getting ahead of risk.
• Level customers up: lead maturity assessments and outcome reviews that raise how customers build — and prove the impact.
• Turn priorities into plans: understand each customer's business priorities and translate them into clear technical plans — empowering them to get the most value from the platform.
• Fuel the wider team: hand qualified expansion signals and renewal insight to Sales — clean handoffs, shared wins.

Experience and Qualifications:

The ideal candidate will:

• Bring hands-on experience in DevOps, software engineering, or platform roles: CI/CD pipelines, Git workflows, and how code quality and security fit into them.
• Carry a business brain: when AI flags a risk or an opportunity, you know what it means for the customer's business — and you move on it, accelerating the upside and defusing the downside.
• Communicate sharply: explaining complex things simply and assertively — to a developer or a VP, in a deep-dive or an executive review.
• Bring analytical firepower: spotting patterns, connecting dots across data sources, and turning them into recommendations people act on.
• Show founding-team energy: building a path for others to follow, taking ownership, acting before being asked, and staying steady while the map is still being drawn.
• Be fluent in English; additional languages such as Spanish and Portuguese are desirable
• Above all: be energetic, coachable, and resilient — with integrity at the core and teamwork as the default. You won't be joining a function; you'll be creating one.
• Bonus points: experience with SonarQube, SAST/AppSec tooling, or developer platforms; customer-facing experience (solutions engineering, consulting, support, customer success); Java or another modern language; comfort in Linux; hands-on with AI coding assistants or agentic development.
