Middle Implementation Engineer (Customer-Facing)

Who We’re Looking For - The Dream Maker

We’re looking for an Implementation Engineer who loves solving integration problems - and wants to own the whole customer journey, not just the technical ticket.

At Chargeflow, you’ll take new merchants from contract signature to go-live. You’ll get into the APIs, webhooks, and data flows yourself when something breaks, and you’ll be the person the customer trusts to get them live - running the project, leading the calls, and keeping every team in sync.

This is a customer-facing role for a technical person: part integration engineer, part project lead. You’ll handle Enterprise implementations end to end, support complex SMB integrations, and help shape how onboarding scales at Chargeflow.

The role starts as a hands-on individual contributor, with the opportunity to build and lead the onboarding team as the function grows.

Born from a deep passion for technology and eCommerce, we’ve developed an AI-driven solution that helps merchants manage credit card disputes, recover lost revenue, and protect their businesses through a unique success-based model.

We’re a tight-knit team of passionate builders and entrepreneurs, united by our mission to revolutionize eCommerce and protect online businesses from chargeback fraud.

What You’ll Own

• Own the technical side of every implementation - troubleshoot API and webhook issues, investigate data flows, and resolve integration problems before escalating to Engineering.
• Take Enterprise customers from contract signature through go-live and first value, as their primary point of contact.
• Build and run implementation plans, timelines, milestones, and risks across several customers in parallel.
• Lead customer calls with both technical teams and executive stakeholders.
• Support complex SMB integrations and act as the escalation point for onboarding blockers.
• Work hands-on with Chargeflow’s payment ecosystem - Stripe, Shopify Payments, PayPal, Adyen, and other payment providers.
• Turn repeated integration issues into better documentation, tooling, and automation.
• Partner with Sales, Product, Engineering, Support, and Customer Success, and feed what you see in the field back into the product.

What You Bring

• 3+ years in a technical, customer-facing SaaS role - Implementation Engineering, Integrations, Solutions Engineering, Technical Account Management, or Technical Onboarding - Must
• Hands-on experience with API-based integrations: you’ve personally troubleshot integration issues, worked with APIs, webhooks and data flows, and can explain what went wrong and how you fixed it - Must
• Experience taking Enterprise or strategic customers from kickoff to go-live, not only supporting them after launch - Must
• The ability to manage several implementations in parallel and keep customers and internal teams aligned - Must
• Confidence leading conversations with executive stakeholders, not only technical teams - Must
• Excellent English, both written and verbal.

Nice to Have

• Experience in fintech, payments, fraud, chargebacks, or eCommerce.
• Familiarity with Stripe, Shopify Payments, PayPal, or Adyen.
• Comfort with tools like Postman, SQL, or log analysis.
• Experience building scripts or automations that remove manual onboarding work.

How We Work

We move quickly, collaborate across teams, and expect people to take ownership from problem to resolution. Successful onboarding at Chargeflow requires both the technical depth to fix what’s broken and the customer leadership to get every implementation over the line.

This is a hybrid role based in our Modi’in office, with 3 days a week in the office.

If you’re a technical person who wants to own the customer journey - not just the integration - we’d love to hear from you.
