Descrizione del lavoro

We are the platform turning browsing into shopping. We connect 200 million shoppers with deals they love while boosting local sales for hundreds of top retailers and brands.

We help consumers save time and money while making smart shopping decisions, and we support retailers and brands in engaging customers from online research to in‑store purchases.

In 2024, Shopfully joined forces with the North American company Flipp, creating a global leader in the sector. Together, we reach 400 million households and serve over 1,000 top retailers and brands across 27 markets, including Europe, Canada, the United States, Latin America, and Australia.

WHO WE LOOK FOR

Every day, millions of users rely on the Flipp app to discover deals, save money, and make smarter shopping decisions. As a Senior Backend Software Engineer, you will join a cross‑functional team responsible for the backend systems that power our iOS and Android applications, ensuring they are scalable, secure, and reliable.

In this role, you will own backend services end to end, contribute to the design of large‑scale systems, and help guide technical decisions within the team.

You will act as a technical leader by influence, mentoring other engineers and raising the overall engineering bar through design, code quality, and collaboration.

You will work closely with Software Engineers, Product Managers, Designers, and other Engineering teams in a collaborative, international environment.

WHAT YOU WILL DO

Your responsibilities span system design, backend development, testing, and technical leadership, with a strong focus on supporting and evolving the distributed backend systems for Flipp and Shopfully’s mobile applications.

Key responsibilities include:

• Design and evolve scalable, secure, fault‑tolerant distributed systems within an event‑driven microservices architecture.
• Own and advance backend service architecture with a platform mindset, creating reusable services, APIs, and shared components that enable internal developer community.
• Translate product requirements into clear, well‑designed technical solutions, collaborating closely with Product, Design, Quality, and Data.
• Own the end‑to‑end software development lifecycle, from technical design, estimations, implementation, testing, deployment to production support.
• Write clean, robust, and well‑tested code, applying SOLID principles, proven design patterns, automated testing, and CI/CD best practices while actively reducing technical debt.
• Act as a senior technical leader, guiding architectural decisions, mentoring through code reviews, and serving as a point of reference during production incidents.
• Integrate AI‑assisted development tools into your daily workflow and help the team adopt effective practices—treating AI tooling as a core part of engineering productivity, not an experiment.

WHAT YOU WILL NEED

• 7+ years of backend or full‑stack development experience designing and building scalable, reliable backend systems.
• Proven experience with AWS services (e.g., Lambda, API Gateway, S3).
• Strong experience with relational and/or NoSQL databases; experience with Docker and Kubernetes.
• Experience with event‑driven systems and messaging (e.g., Kafka, SQS/SNS).
• Strong system design expertise with hands‑on experience operating and troubleshooting production systems.
• Software engineering practices:
  • Strong grasp of clean‑code principles and backend design patterns.
  • Experience writing and maintaining automated unit and integration tests.
  • Experience improving CI/CD pipelines and enforcing testable coding practices.
  • Proficient with Git and modern collaboration workflows.
• Demonstrated use of AI tools in software workflows, with the ability to articulate benefits, limitations, and lessons learned.
• Willingness to participate in on‑call rotations and support production systems.

NICE TO HAVE

• Experience with PHP, Serverless Framework, OpenSearch / Elasticsearch, Protobuf, gRPC.
• Experience with Go.
• Experience building backend systems that support mobile applications.
• Experience contributing to shared platforms or organization‑wide technical initiatives.
• Exposure to large‑scale, distributed systems serving millions of users.
• Experience contributing to or maintaining open‑source libraries.

Salary Range: €50,000 – €65,000 fixed gross salary per year.

TO FEEL AT HOME – YOU NEED

• Progress Over Perfection: We move forward. Always. In a fast‑moving world, speed with purpose beats certainty without action. Momentum matters—not for its own sake, but because it drives results.
• Clarity Through Transparency: We bring each other along. We work in teams, not silos. Transparency gives context, and context enables action. That means we share decisions early, publish work in progress, and document outcomes so others can learn, move faster, and build better.
• Learn Loudly: We grow by doing and by daring. Big bets unlock big breakthroughs. But real innovation demands risk, and risk always carries the possibility of failure. That’s not a flaw. It’s the price of ambition.
• Challenge with Empathy: We speak up, even when it’s hard—because candor shows care, and leads to better outcomes. Listening deeply is how we grow. Disagreeing openly is how we build trust.

Always Build Better: We are builders—of products, systems, and ideas. But more than that, we are builders of better. Better has no finish line. It’s a mindset.

We value diversity and actively encourage it. We focus on potential rather than having a “perfect” CV. If this role excites you and you believe you could grow into it—even if you don’t tick every single box in the requirements—we’d love to hear from you!
