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.

Are you looking to build a meaningful career in cyber security, protecting millions of people around the world? We are looking for a Senior Backend Engineer to join our Technology team in Bengaluru, India.

In this role, you will work closely on developing and maintaining tools that support our operator partners. This includes diverse activities like developing our new Security Business Platform, building new microservices, and creating and maintaining connections between internal systems. You will also provide analytics and reports to help our operator partners operate efficiently and effectively.

We are looking for a proactive and adaptable individual who thrives in dynamic environments and is excited to grow with us. Our team embraces diversity of thought and believes that collaboration is key to success. We value open communication — the ability to listen, discuss ideas, and give and receive constructive feedback. If you're naturally curious, eager to learn, and passionate about sharing knowledge, you'll feel right at home here.

This role is based in our Bengaluru office, where we work in a hybrid setting.

Key responsibilities in this role:

• Design, build, and maintain high-performance, high-availability backend services and APIs that support frontend developers, mobile client teams, and external partners
• Lead the development of new services and drive architectural decisions within our large-scale microservices and SOA architecture, establishing best practices for distributed systems design
• Lead initiatives to meet performance and scalability goals, and take full ownership of services and components — including on-call duties and incident response leadership
• Champion automated testing across the team and create comprehensive documentation to enable self-service and knowledge sharing
• Mentor junior engineers and contribute to hiring and technical interviews
• Leverage AI-powered development tools (such as GitHub Copilot, Claude, or similar) to enhance productivity, code quality, and development workflows

What are we looking for?

• 8–12 years of software engineering experience with a degree in Computer Science or a related field, including expert-level coding ability in Java and related frameworks such as Spring Boot
• 7+ years of hands-on experience with AWS, with deep knowledge of core services (EC2, Lambda, S3, RDS, DynamoDB, ECS/EKS, IAM), cloud networking, security, and cost management
• Proven experience with Infrastructure as Code tools (Terraform, CloudFormation, or CDK) and designing multi-region, highly available distributed systems
• Strong object-oriented and functional design abilities, with a focus on clean, maintainable code and a solid understanding of data structures and algorithms
• A track record of leading technical initiatives, mentoring engineers, and delivering results in Agile environments — with excellent problem-solving and debugging skills for complex distributed systems
• Full professional proficiency in English (written and spoken), with the ability to articulate technical concepts clearly to both technical and non-technical stakeholders

You'll stand out if you have:

• Experience with CI/CD pipelines, DevOps practices, containers (Docker, Kubernetes), and AWS deployment pipelines
• Proficiency in Python and/or Scala
• Experience with Kafka or other message bus / distributed log infrastructure
• Exposure to NoSQL databases (DynamoDB, Cassandra, MongoDB) and SQL databases
• Background in cybersecurity or security-focused product development
• Experience using AI tools for code review, documentation generation, test creation, or architectural analysis
• Contributions to open-source projects or technical publications

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.

A security vetting will possibly be conducted for the selected candidate in accordance with our employment process.
