Job Description

For over 35 years, F-Secure has led the cybersecurity industry with our 200+ service provider partners. As the home of scam protection, we're reimagining how we protect people from modern threats through cutting-edge scam detection and solutions that are setting the industry standard. We bring together the sharpest minds of cyber security with a shared purpose: to protect people from modern threats. Here, you’ll have a real impact, making every digital moment more secure for everyone. You’ll thrive and grow in our Fellowship culture, where we dream big, trust, and challenge each other to deliver results and move with speed. You’ll be welcomed into a diverse, global team with an informal and collaborative culture where your voice truly matters.

Join us in securing the digital world together – where your work will make a lasting impact.

We're looking for a skilled and motivated Senior Backend Developer with strong AWS expertise to join our team. This is a hands-on role where you'll design and implement scalable cloud architecture that powers the services protecting tens of millions of users worldwide. You'll work on robust backend systems, translating business requirements into effective, production-grade AWS solutions — and you'll play a key role in shaping how we build and scale our cloud infrastructure.

You'll join a collaborative engineering environment where you can take ownership of technical direction, contribute to architecture decisions, and work alongside talented colleagues across our global offices. If you enjoy solving complex backend challenges and want your work to have a meaningful impact on digital security, this is the role for you.

This position is based in Bengaluru, India, and offers hybrid working flexibility. You'll collaborate closely with teams in Finland, Malaysia, Slovakia, and the US, contributing to products that serve tens of millions of users across 50+ countries.

Key responsibilities in this role:

• Own and lead end-to-end architecture design, delivering scalable, secure cloud solutions aligned with business and technical goals
• Develop, deploy, and monitor backend services and cloud-native applications on AWS
• Implement and manage CI/CD pipelines along with automated monitoring, alerting, and observability tooling
• Collaborate with cross-functional teams to enhance system architecture, security, and performance
• Provide technical leadership and support, including guidance on production issues and complex engineering challenges
• Evaluate and integrate emerging technologies to improve system efficiency and developer productivity

What are we looking for?

• 5+ years of experience working on backend development and AWS cloud architecture
• Strong backend development skills in Java, Python, or similar languages, with a deep understanding of data structures and algorithms
• Hands-on experience with core AWS services (EC2, S3, Lambda, RDS, DynamoDB, VPC, IAM, EKS/ECS) and proficiency with Docker and Kubernetes
• Experience with relational and NoSQL database design, as well as message queue systems such as Kafka
• Familiarity with monitoring and observability tools (e.g. CloudWatch, Prometheus, Grafana, ELK) and strong testing discipline (JUnit, PyTest, TestNG, or similar)
• Proven ability to lead design discussions, code reviews, and system architecture decisions within Agile/Scrum teams
• Full professional proficiency in English

You'll stand out if you have:

• AWS Certified Solutions Architect – Associate (or higher)
• Experience with DevOps practices and Infrastructure as Code (e.g. Terraform, AWS CDK)
• Background in startups or experience building platforms from the ground up
• Familiarity with cost optimization, security compliance, and the AWS Well-Architected Framework
• Participation in tech communities or open-source contributions

What you will get from us?

• Welcome to the good side – the home of scam protection! Work with industry-leading experts defining the future of cybersecurity and scam protection
• Be an AI pioneer, not a follower. Access industry-leading tools like Claude and Claude Code, with full support to integrate AI into your daily work while others are still figuring out policies. We're not asking "if" but "how" AI transforms our work, positioning you at the forefront of the industry.
• Thrive in our Fellowship culture where we empower, trust, challenge, and support each other in doing our best work.
• Flexible work that works for you – hybrid and remote options with team-agreed ways of working.
• Inclusive environment with flat, approachable leadership in our diverse global community.
• Comprehensive global benefits including Employee Share Savings Plan (ESSP), Fellow Member of the Board opportunities, and Annual Protect & Educate paid volunteer day.
• Wellbeing support through personal coaching services and one hour per week for personal recharging.
• Continuous growth via F-Secure Academy, Leadership programs, AI training, mentoring, and dedicated Learning Week.
