Since 2011, we’ve tirelessly delivered on our promise to customers sending money globally, providing secure, simple, and reliable ways to manage their money, ensuring true peace of mind. Whether it’s supporting loved ones back home, growing a business across continents, or pursuing new opportunities abroad, we’re not just here to move money— we’re here to move our global customers forward.

If that’s you and you’re ready to do the most meaningful work of your career—we invite you to join over 2,800 passionate Remitlians worldwide who are united by our vision to transform lives with trusted financial services that transcend borders.

About the Role:

Join us as a Senior Software Development Engineer (SDE III) on Remitly's Content Platform Team! Our mission is to build scalable, high-performance web architectures that enhance search engine discoverability, improve user experience, and support organic growth. You'll handle complex technical challenges in SEO, AEO (Answer Engine Optimization), content delivery, and web performance optimization at scale. You will report to a Kraków-based Manager.

You Will:

Lead the design and implementation of large-scale web architectures to improve global performance and search and answer engines discoverability.
Oversee complex, team-level projects end-to-end: clarifying requirements, breaking work into parallel tasks, and guiding teammates toward on-time delivery.
Optimize page speed, Core Web Vitals, and other performance metrics across mobile and desktop platforms, ensuring solutions are resilient, extensible, and scalable.
Configure and manage CDNs (e.g., CloudFront, Cloudflare, or others) to ensure scalability, reliability, and security for high-traffic experiences.
Implement and maintain SEO/AEO features like structured data, sitemaps, canonical tags, and hreflangs, ensuring our content platform sets a high technical standard.
Drive and participate in technical design reviews for Content Platform systems, making smart trade-offs that avoid unnecessary complexity and long-term risk.
Collaborate across teams (engineering, marketing, and product) to deliver scalable, SEO/AEO-friendly solutions that support Remitly's broader product and growth strategy.
Mentor other engineers through code reviews, design discussions, and pairing, raising the bar for code quality, observability, reliability, and use of modern tooling

You Have:

6+ years of software development experience with a focus on performance and scalability, including leading delivery of complex features or projects within a team.
Experience building and optimizing large-scale web architectures that are secure, maintainable, and scalable in a production environment.
Strong understanding of server-side rendering (SSR), hydration, and modern web frameworks such as React, Next.js, Remix, or SvelteKit.
Solid knowledge of backend programming languages such as Java, Golang, or similar, and experience designing APIs and services that support web applications.
Experience with cloud platforms and microservices, including designing, integrating, and operating distributed services in production (e.g., AWS, GCP, or Azure).
Proficiency in performance monitoring and observability tools and in using metrics/logs to diagnose and resolve production issues.
Demonstrated technical leadership by driving technical documentation, design and delivery across complex projects, making trade-offs, and mentoring engineers to improve team standards.
Experience with modern software development practices, including CI/CD, code reviews, and secure coding standards.

Good to have:

Background building and operating high-scale web systems.
Hands-on experience configuring and optimizing CDNs for performance and scalability in multi-region architectures.
Experience with global web performance challenges and internationalization (i18n).
Solid grounding in SEO/AEO, including structured data, canonicalization, and search bot optimization.
Knowledge of headless CMS platforms (e.g., Contentful, Sanity, Strapi) and how to design content models and delivery APIs that support localization, experimentation, and high-quality content delivery.

What our Remitlians say

Evelyne Kuo

Program Manager - Technical

On the Security & Privacy team, I reimagine what’s possible by going beyond traditional compliance to create a culture where security is part of everyone’s day-to-day — through programs like our champion network, engaging training sessions, and company-wide awareness events that make security approachable and empowering.”

What our Remitlians say

Amara Agbo

Software Development Engineer II

To me, reimagining what’s possible means constantly learning new technologies and applying cutting-edge solutions to build localized systems that scale across currencies, countries, and regulations. The challenges we solve at Remitly don’t just strengthen our platform — they expand financial access for millions of people worldwide. That’s what makes the work both exciting and impactful.”

What our Remitlians say

Rosa Castellon Herrera

Senior Team Manager - QA

Stand for excellence means to me always raising the bar, pushing through discomfort, to deliver our best to our teams and customers every time. We come together as a team to share ideas to develop a rubric that helps us deliver impactful results.”

Stephanie Cameron

Senior Product Manager

On the product team at Remitly, I’m trusted to make decisions that drive real impact—not just for my team, but for the business and our customers. I’m encouraged to take ownership of problems even when they’re outside my immediate scope, to speak up, and to bring the right people together to solve them. Lately, that’s meant working on real-time FX and funding tools that support our treasury team in lowering transaction costs—so we can pass those savings on to our customers. That trust and cross-team collaboration make it easy to stay focused on what really matters in the long run.”

What our Remitlians say

Nadav Yekutiel

Senior Manager - Analytics

At Remitly, diving deep has meant pushing past easy answers to truly understand what our customers need. I’ve seen our analytics teams uncover insights that weren’t obvious at first glance — like identifying hidden friction points in the customer journey that, once solved, improved both experience and trust. This commitment to going beyond the surface makes our recommendations stronger, and it’s a big part of how we deliver meaningful impact across the business.”
