🚀 Who we are & What we believe?

We believe the internet is the great equalizer and enabler. It provides essentially unlimited access to knowledge, education, entertainment, services and commerce. And it’s an incredible tool to publish, create, share and communicate.

We think everyone deserves first-rate internet, and we have gone about creating an internet service that we ourselves want to use.

We believe in the power of curiosity, creativity and imagination. We use technology to realize our creations, to simplify and to enable. In addition, we add in hard work, sheer sweat and will power where that is not quite enough. If the idea is right, “that can’t be done”, or “that’s not how things are done” will not stop us.

Offering the best customer experience is dear to our hearts. Our industry is not very good at this, and we have lots of room to improve. We want to be the best and are looking for a leader that shares our passion.

If that’s you, we’d love to meet and get to know you. Let’s talk about how we can work together to make it happen!

About Fundraise Up
We’re Fundraise Up - a global fundraising platform built to make donating to nonprofits fast, seamless, and accessible to all. Every month, our technology powers tens of millions of dollars in donations across the globe. We focus on innovation that directly impacts results: faster load times, higher conversion rates, global payment support, and accessibility-first design.

Our platform is trusted by many of the world’s leading nonprofits, including UNICEF, the Alzheimer’s Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, we’re recognized not just for our impact - but for the quality of the product we deliver.

A Truly Global Product
We operate in the enterprise segment, serving nonprofit organizations across North America, the United Kingdom, Australia, and Europe.

We’re building a
large and complex product ecosystem
that serves nonprofits, donors, and partners around the world. The platform includes a modern
checkout experience and customizable widgets
(each a standalone SPA),
donor, organization, and partner portals
,
admin tools
, and several internal apps.

The Team
We are a distributed team of 160+ product professionals. Our team members are mainly based across Spain, Poland, Portugal, Georgia, Armenia, Serbia, Turkey, and Cyprus.

Despite our scale, we operate like a focused team - where every task matters and every voice is heard. We value thoughtful collaboration, strong engineering practices, and a product mindset. You’ll be joining a team where quality, mentorship, and mutual respect come first.

About The Role
We are looking for a proactive and security-minded
IT Support Engineer (L2)
to join our global team. As a core member of our L2 team, you will share responsibility for complex technical escalations across time zones. Beyond operational support, you will take
full ownership of Access Governance and SaaS administration
. We are looking for an engineer who doesn't just follow processes but actively seeks to automate them, improving our efficiency and security posture through continuous integration and smart tooling.

What You’ll Do

• L1 escalations: intake, triage, diagnosis, and resolution of tickets not closed at L1. Includes admin operations in corporate tools, access provisioning, complex technical requests, integrations, and alerts from monitoring systems. Work within agreed SLAs for response and resolution; escalate further when outside scope or ownership boundaries.
• Onboarding & offboarding support: creation and deprovisioning of accounts in corporate SaaS tools, MDM enrollment where applicable, credential handoff, and baseline laptop setup in line with internal processes.
• Incident response: phishing, account compromise, lost/stolen devices, malware, and other security alerts — containment, remediation, and follow-up actions using documented playbooks.
• Automation & integrations: drive continuous improvement through scripts, APIs, Zapier/n8n (or equivalents), and integrations to eliminate repetitive manual work. Automation does not have to be your current strongest skill, but initiative and genuine interest are required. You can consult with our Tools Engineer, but ideas and ownership should come from you.
• L1 mentoring & documentation: provide regular feedback and coaching, maintain and improve L1 instructions and runbooks, and document automations and recurring operational procedures.
• Corporate SaaS administration: admin ownership over our core collaboration and identity stack (e.g., Slack, Notion, Google Workspace, 1Password) plus other corporate SaaS tools — configuration, access policies, audits, and license usage control.
• SaaS lifecycle management: maintain the SaaS registry in Notion, provide reporting for Vendor Management ahead of renewals; evaluate new tools and roll out after approval; decommission outdated tools.
• Identity-related incident playbooks: develop and maintain playbooks for phishing, account compromise, suspicious sign-ins in Google Workspace, and credential/access rotation.
• At Fundraise Up, AI is a default tool, not an experimental one. We expect every team member to actively use AI in their day-to-day work, identify where AI can change the shape of problems in their function, and grow their fluency as the tools evolve. You should already be using AI meaningfully in your work and understand where it adds value and how it can improve the way you operate.

Requirements

• 5 years in IT support, with at least 3–5 years at L2 / Sysadmin level.
• Strong troubleshooting skills and end-to-end ticket ownership (intake, triage, resolution, escalation when out of scope).
• Hands-on experience with macOS administration and end-user troubleshooting.
• Strong Google Workspace admin skills (roles, logs, security settings).
• Understanding of security and incident handling (phishing / account compromise).
• Comfortable with identity & access work (RBAC, audits, access reviews; understands how SSO / SAML / SCIM affect onboarding/offboarding).
• Ability to write and keep documentation up to date (runbooks, checklists, incident playbooks); can mentor L1.

Strong plus

• Admin ownership in multiple corporate SaaS tools (e.g., Slack/Notion + project management + ticketing/support tooling) — access policies, audits, license management
• Automation experience (scripts / APIs / Zapier / n8n or equivalents). We can support your growth here, but you should be self-driven and eager to automate your own work.
• Knowledge of 1Password or similar in a corporate context (if not covered above as a must-have)
• Experience with Jira Service Management (as a user or admin) or similar tools
• Familiarity with vendor/license management processes (renewals, usage reporting)
• Experience with MDM / endpoint tooling (for collaboration with Devices & Infrastructure owner)

Why work with us

• A strong, collaborative product team that owns what it builds
• Clear product vision and access to real customer feedback from global nonprofit leaders
• Flat structure: no politics, just great work with great people
• Transparent company culture-we share how we’re growing, where revenue comes from, and what’s next
• Long-term focus: we offer equity options and value sustained, meaningful contribution

Benefits

• 31 days off
• 100% paid telemedicine plan
• Home Office Setup Assistance: the company offers assistance with purchasing furniture (office chair, office desk, monitor) and other items to create a comfortable workspace
• English learning courses
• Relevant professional education
• Gym or swimming pool
• Co-working
• Remote working

We are an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
