As a Customer Success Engineer at Iterable, your day-to-day work is highly collaborative and technically diverse. You are the technical backbone of the customer success organization, stepping in to solve the problems that standard support channels or account managers cannot resolve alone.

Your primary responsibility is to guide enterprise clients through their initial technical onboarding and ongoing platform optimization. This involves reviewing their database schemas, advising on API integrations, and troubleshooting complex campaign delivery issues. You will routinely inspect API logs, write custom HTML/CSS workarounds, and help clients build advanced dynamic queries to segment their user bases.

Beyond direct client interaction, you serve as a critical feedback loop for internal teams. You will collaborate closely with Iterable's Product and Engineering departments, translating common client pain points into feature requests and helping debug platform-level anomalies. You will also author internal documentation, troubleshooting guides, and best-practice resources to scale the technical knowledge of the wider Customer Success team.

To be competitive for the Customer Success Engineer position, you must demonstrate a strong blend of technical expertise and client-facing experience.

• Technical skills – A strong foundation in web technologies is mandatory. You must be highly proficient in HTML, CSS, and REST APIs. Familiarity with SQL, JSON, webhooks, and modern scripting languages (such as JavaScript or Python) is highly valued.
• Experience level – Typically, successful candidates have 2 to 5 years of experience in a technical support, solutions engineering, technical account management, or customer success engineering role, preferably within a SaaS or marketing technology ecosystem.
• Soft skills – Exceptional active listening, verbal and written communication, and project management skills are essential. You must be comfortable presenting to both executive stakeholders and developer teams.

Must-have skills:

• Strong proficiency in writing and troubleshooting HTML and CSS.
• Deep understanding of REST APIs, HTTP protocols, and JSON payload structures.
• Proven experience managing technical client relationships.

Nice-to-have skills:

• Experience working with marketing automation platforms, Email Service Providers (ESPs), or Mobile Push notification systems.
• Familiarity with mobile SDK integration (iOS and Android).
• Experience with templating engines like Handlebars.

Q: How technical is the Customer Success Engineer interview compared to a software engineering interview? A: While you do not need to solve complex algorithmic puzzles or system design problems, the technical evaluation is rigorous. You must be able to write and debug HTML/CSS live, explain API architectures, and troubleshoot data-flow issues in real-time.

Q: What is the "Passion Presentation" and how should I prepare for it? A: This is a 30-minute presentation where you teach the panel about something you love. It does not have to be technical. The interviewers are assessing your communication skills, how you structure information, your enthusiasm, and how you handle questions under pressure.

Q: How long does the entire interview process typically take from start to finish? A: The timeline generally spans 3 to 5 weeks. This depends on scheduling availability for the multi-hour final panel and how quickly the team processes the technical assessment results.

Q: What is the hybrid or remote work policy for this role at Iterable? A: Iterable supports hybrid work models in offices like San Francisco, Denver, and London, while also offering fully remote options for qualified candidates in various regions. Be sure to clarify the exact expectations for your location with your recruiter.
