Senior Implementation Lead / Project Manager (North America)

If you’ve been looking to join a fast-growing startup with a bold vision of a world where doing good is built into everything we do, then you’ve found the right place!

Backed by General Catalyst, the same investors behind Stripe and Airbnb, we’re one of Europe’s fastest-growing SaaS companies – building the technology that enables global enterprises to give, volunteer, and fund with confidence.

Our mission at Goodstack is to revolutionize how the world does good 🌎.

As a Series A social impact startup, we power global change through technology. We enable companies to seamlessly integrate positive impact into what they do through a unified platform while supporting nonprofits in gaining access to cutting-edge technology and finding new funding streams.

Global brands, including Google, OpenAI, TikTok, LinkedIn, HSBC, Atlassian and Twilio - as well as thousands of nonprofits, including the Red Cross, Cancer Research, and Oxfam - use Goodstack to make a difference.

In 2025 alone, we have facilitated $5 billion in donations to good causes. But this is just the beginning. We're building the world’s leading platform that powers donations to nonprofits globally.

To keep our momentum and deliver consistently high value to our partners, we need incredible people to help us on our journey – we need you 🫵

In this role, you’ll lead new client implementations from kickoff through to launch – coordinating cross-functional teams, managing technical and operational setup, and ensuring each client goes live on time, fully configured, and ready to scale.

You’ll work closely with Solutions Consulting, Solutions Engineering, Product, and Client Success teams – acting as the operational heartbeat between commercial close and client adoption.

• Build the implementation frameworks required to be successful in this role.

• Partner with internal and client stakeholders to define scope, success criteria, and project plans.

• Build and manage structured implementation plans – clear milestones, ownership, dependencies, and deadlines.

• Lead all product implementation types with accountability for delivery quality, pace, and satisfaction.

• Serve as the primary client contact during implementation – managing expectations, surfacing risks, and ensuring constant communication.

• Coordinate cross-functional workstreams (technical, product, data, comms) to keep everything on track.

• Track progress through key metrics (timelines, resourcing, client satisfaction, risk logs).

• Ensure a seamless transition to the post-live team – handing over documentation, training, and support context.

• Capture insights from implementations to inform process improvements and product enhancements.

• Continually work on Goodstack’s delivery methodology and playbooks to drive faster time-to-live and higher adoption.

• You’ve led multiple enterprise implementations from kickoff to go-live with exceptional client feedback.

• Average implementation time has decreased through improved planning and proactive risk management.

• You’ve established repeatable delivery frameworks that the broader team adopts.

• Clients consistently describe the Goodstack onboarding experience as “best-in-class.”

• You’re trusted by Sales, Product, and CS as the go-to operator who gets clients live, fast, and happy.

• Clear and concise communicator – you keep stakeholders aligned and informed without overcomplicating.

• Exceptional project and stakeholder Lead – you drive accountability, pace, and structure across multiple teams.

• Commercially minded – you understand how faster go-lives translate to stronger adoption and revenue.

• Technically fluent – you grasp data flows and integrations and can problem-solve with engineers and product teams.

• Calm under pressure – you stay composed, prioritize well, and make clear decisions when things get busy.

• Collaborative by default – you bring people together, cut through noise, and get things done.

• 5+ years in implementation, delivery, or project management within SaaS or enterprise tech.

• Proven record managing full lifecycle implementations – from scope through to live.

• Strong stakeholder, communication, and risk/change management skills.

• Experience coordinating internal and client teams across time zones.

• Proficiency in project management tools (Asana, Jira, Notion, Hubspot, G-suite, etc.) and frameworks (Agile/Waterfall hybrid).

• Confident managing both operational and technical workstreams.

• Experience in fast-paced, high-growth environments where processes evolve rapidly.

• CSR, ESG, or social-impact technology.

• Experience working with enterprise clients like Microsoft, Airbnb, or TikTok.

• Certifications (PMP, PRINCE2, Agile/Scrum).

• Experience with APIs or SaaS integrations.

• Building documentation, templates, and process improvements that scale.
