Technical Support Engineer (H/F)

iRaiser is a leading European SaaS fundraising platform dedicated to nonprofits, charities, and NGOs. Following our continuous growth and strategic integrations (including Kentaa andStockcrowd), we proudly empower over 900 organizations across Europe and internationally to raise billions of euros securely. Our ecosystem includes advanced online donation solutions, peer-to-peer platforms, crowdfunding, and dedicated CRM tools. Security, high-volume transaction processing, and a seamless donor journey are at the heart of what we do. To support our scale and reinforce our operational excellence, we are looking for a versatile, hands-on, and bilingual Technical Support Engineer. As a Technical Support Engineer, you will sit at the crossroads of Customer Support, Customer Success (CSM), and Revenue Operations (RevOps). In our fast-paced SaaS environment, you will be a technical Swiss Army knife, managing complex data flows, technical configurations, and acting as the vital link between our clients and our development teams. This is a high-ownership role: you will be expected to manage and drive your own internal technical mini-projects independently, from scope definition to delivery, without needing constant hand-holding.

Your mission will be divided into three strategic pillars:

1. Product Technical Support & Tech Translation (Donation Form): * Take ownership of advanced technical support tasks on our core product, built on PHP 8. * Troubleshoot, debug, and resolve complex issues related to donator tracking, financial transactions, data synchronization, and payment gateways, … * Act as a two-way technical translator and key intermediary: Analyze, document, and translate complex client issues into actionable technical specifications for our Product and R&D teams. Conversely, demystify and simplify complex technical resolutions or new product features into clear, accessible documentation, training, and guides for our Support and CSM teams.

2. SaaS Infrastructure, Tooling & Project Management: * Drive internal technical projects: Take the lead on improving our internal

tools.

• Identify operational bottlenecks and independently build, maintain, or improve internal tooling and scripts to empower the Customer Support teams.
• Manage client-facing SaaS technical configurations, including client domains management (DNS, SSL/TLS certificates, SMTP setup) and Instant Payment Notifications (IPN / Webhooks).
• Oversee external data flows and synchronizations towards clients’ CRMs.

1. RevOps Assistance & Backup: * Act as a strong technical partner and backup for our Revenue Operations

function.

• Help manage, automate, and optimize our internal HubSpot CRM ecosystem (workflows, integrations, and data consistency across pipelines) and its connections with other tools.

Language Skills: Bilingual English (excellent written and spoken level is mandatory for our international context) + Fluent in either French or Spanish.

• Experience: 3+ years of experience in Technical Support, Application Support, or a

technical RevOps/SysAdmin role within a SaaS or FinTech environment.

• Technical & Project Skills:
• Project Ownership: Proven ability to manage small-to-medium technical projects or tool migrations independently.
• Solid understanding of Web environments, including PHP and JavaScript troubleshooting.
• Fully comfortable with SaaS delivery technicalities: DNS management, SMTP, and SSL certificates.
• Good knowledge of APIs, webhooks, data synchronization, and database queries (SQL).
• Experience with HubSpot CRM is highly desirable; experience with Zendesk is a strong plus.

• Understanding of payment gateways or e-commerce infrastructures is appreciated.

• Soft Skills:
• Strong autonomy & accountability: You are a self-starter who doesn’t need hand-holding; you take ownership of a problem until it’s fully resolved.
• Great communication & pedagogy: Ability to “translate” complex technical issues for non-technical internal teams, and vice versa for developers. You excel at making technical concepts easy to understand for everyone.
• Highly versatile, proactive, and curious (“touches everything” mindset).
• Team player, adaptable, and comfortable managing multiple technical priorities.
