The role
We’re hiring a Technical Support Engineer who loves solving customer problems, digging into Java/Spring services, and partnering with Product & Engineering to drive outcomes. You’ll be the primary technical point of contact for enterprise customers: triaging, troubleshooting, and resolving issues; coordinating hotfixes and monthly releases; and ensuring an outstanding, measurable customer experience.
This is a hands‑on, customer‑facing role in a product company (not a services/SI model). Ideal for engineers with 5–10 years building, supporting, or operating commercial software products—especially B2B commerce or enterprise SaaS.
What you’ll do
- Own incident triage and resolution: reproduce issues, analyze logs, identify root causes, and drive fixes across Java/Spring services, integrations, and data layers.
- Coordinate hotfixes and monthly releases with Product, QA, and Engineering; validate fixes and change notes.
- Serve as a trusted technical advisor to customers and backup to the Customer Success Manager; translate business impact into technical priorities.
- Build crisp runbooks, KB articles, and dashboards; improve alerting/observability and reduce MTTR.
- Deliver ad‑hoc reporting and data investigations (SQL/JSON/XML) to answer “why” with evidence.
- Champion product quality: escalate recurring defects, propose hardening, and validate performance and scalability fixes.
- Participate in a light on‑call rotation for P1/P2 incidents (shared team responsibility).
What you’ll bring (must‑haves)
- 5–10 years in engineering/technical support roles at product companies (SaaS or commercial software).
- Strong in Java and the ecosystem (Spring, Hibernate/JPA), REST/SOAP APIs, and integration patterns.
- Solid with SQL (e.g., PostgreSQL) and exposure to NoSQL; comfort with data formats (JSON, XML).
- Competent with Git, Maven, CI/CD concepts, and environment debugging (logs, metrics, tracing).
- Clear, confident customer communication (written, verbal, and executive‑ready), with a steady, proactive presence during incidents.
- Hybrid work commitment: able to be onsite in Los Altos 3 days/week.
- Work authorization: Authorized to work in the U.S. for any employer; no current or future visa sponsorshipavailable for this role.
- Availability to start within 2–4 weeks of offer.
Nice to have
- Experience with B2B E-Commerce, B2C E-Commerce Software, Search Engines, CRM, ERP software solutions.
- Familiarity with MACH, composable commerce, or B2B e‑commerce domain concepts (catalog/pricing/inventory/order/Payments).
- Exposure to observability tools (e.g., Datadog, New Relic, OpenTelemetry) and ticketing/CS tools (Jira, Zendesk, Salesforce).
- Knowledge of secure SDLC practices and performance troubleshooting.

- Customer Success • Innovation • Partnership • Positive Attitude • Teamwork
“None of us are as smart as all of us.” We win together—customers, partners, and teammates.
