Original job description

This is Adyen

Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition.

For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster.

Senior Implementation Engineer

As a Senior Implementation Engineer at Adyen, you will lead the design and delivery of mission-critical payment integrations for some of the world’s largest global companies.

You will influence how global enterprises design and operate their payment infrastructure at scale. Your work will directly impact the reliability, performance, and scalability of payment flows used by millions of end customers worldwide.

This role is focused on solving complex, high-scale technical challenges. You will also shape technical direction, influence product evolution, and mentor implementers across the organization.

This position is based in Toronto, and the ideal candidate is both consultative and technical.

You will design and scale highly resilient, high-performance integration architectures while helping raise the technical bar across the implementation organization.

What you’ll do:

Deliver complex, multi-region enterprise integration projects
Design scalable, high-availability architectures for global merchants handling large transaction volumes
Define and ensure technical standards across implementation engineering teams
Act as a strategic technical advisor in both pre-sales and delivery phases, shaping solutions alongside Sales and senior merchant stakeholders
Shape industry standards and the broader ecosystem by defining how large-scale payment architectures are built and scaled
Foster best practices in reliability, scalability, security, and system design (e.g. idempotency, fault tolerance)
Mentor and support Implementation Engineers across the organization
Partner with Product and Engineering to influence platform evolution and new product design
Manage critical escalations and ensure stability of high-scale merchant integrations

Who you are:

12+ years of experience in software engineering or technical consulting with deep API integration experience
Deep system design and distributed systems expertise
Ability to operate as a solution architect and trusted advisor in complex, enterprise environments
Experience contributing to production-level systems with pragmatic engineering trade-offs
Comfortable engaging with senior technical and business stakeholders
Proven ability to mentor and develop engineers
Solid decision-making capability in complex and ambiguous environments
Passion for raising technical excellence across teams and organizations
You thrive in environments where collaboration, accountability, and impact go hand in hand

Our Diversity, Equity and Inclusion commitments

Our unique approach is a product of our diverse perspectives. This diversity of backgrounds and cultures is essential in helping us maintain our momentum. Our business and technical challenges are unique, and we need as many different voices as possible to join us in solving them - voices like yours. No matter who you are or where you’re from, we welcome you to be your true self at Adyen.

Studies show that women and members of underrepresented communities apply for jobs only if they meet 100% of the qualifications. Does this sound like you? If so, Adyen encourages you to reconsider and apply. We look forward to your application!

What’s next?

Ensuring a smooth and enjoyable candidate experience is critical for us. We aim to get back to you regarding your application within 5 business days. Our interview process tends to take about 4 weeks to complete, but may fluctuate depending on the role. Learn more about our hiring process here. Don’t be afraid to let us know if you need more flexibility.

This role is based out of our Toronto office. We are an office-first company and value in-person collaboration; we do not offer remote-only roles.

The annual base salary range for this role is $170,000-$240,000 CAD; to learn more about our compensation philosophy, please click here.
