Senior Software Engineer

About Kasada Join us in stopping bad bots, for good! Kasada protects millions of online users everyday. Founded to stop automated bot attacks, we believe the internet should be a safe place for everyone. Bad bots are highly destructive. They take over accounts, steal content, overload systems and infrastructure and cause billions of dollars in damages every year. Seeking to restore trust in the internet, Kasada stops bots at the very first request including those that have never been seen before.

About the role

Kasada has an exciting opportunity to join our Account Intelligence team, the team responsible for defending our customers against fraud and malicious automation. Attackers use ever changing toolsets to launch highly costly attacks on our customers, and we handle an immense volume of traffic (think a billion requests per day) safeguarding renowned brands and protecting people online. Every millisecond counts!

As a Senior Software Engineer on the team, you will help shape our technical direction, architecting greenfield systems at the core of how we tell legitimate users apart from adversaries. You won't be confined to traditional three-tier applications. You will lead design discussions, work closely with our team lead on where the product goes next, and build the data-intensive systems that power our detection capabilities. This role involves close collaboration with engineering, research, and product teams across Kasada.

What you will be doing

• Shape the architecture: Lead the design of greenfield systems within Account Intelligence, from data modelling through to production, and help set the technical direction for the team.
• Design and implement features on our market-leading product, staying hands‑on across the stack with a focus on backend and data‑intensive systems.
• Lead design discussions: Drive architecture conversations within the team and across engineering, making your reasoning clear and bringing others along.
• Build low‑latency, massively scalable solutions that cater for millions of requests per minute.
• Mentor and collaborate: Pair with teammates, lift the design capability of the team, and support other teams as they build on the systems we own.
• Collaborate closely with other product and engineering teams.
• Be involved in architecture design discussions in how we can build efficient solutions.

What you will be working with

• NodeJS
• TypeScript
• A mix of databases such as Postgres, Redis, Clickhouse, etc.
• AWS (Kubernetes, Lambda, S3, EC2, etc.)
• GitHub

What you will bring

• At least 5 years of experience working on backend problems (Node/TypeScript experience a plus).
• Strong data modelling skills and experience with various data storage solutions (both SQL and NoSQL).
• Prior experience designing system architectures, and comfort designing a system from the ground up given product requirements.
• A good understanding of AWS services and experience working with containers.
• Exposure to highly scalable architectures and infrastructure as code.
• Experience mentoring engineers or leading technical initiatives within a team.
• A great ability to communicate highly technical concepts to non‑technical audiences.
