Senior Full Stack Engineer

About Cakewalk Cakewalk is access management for the entire workforce: AI agents and human identities. We built a single platform to govern and secure access in companies through policy-first access management, runtime provisioning, and identity-linked lifecycles. We are looking for a Senior Full-Stack Engineer (m/f/d) to join our ambitious engineering team and help accelerate our product development. You will join a team of 10 engineers as a senior individual contributor, reporting to an Engineering Manager. This role is for someone who combines technical strength, grit, and self-reflection, and who is excited to take meaningful ownership in a fast-moving environment.

About the Role
As a Senior Full-Stack Engineer, you will build and improve customer-facing functionality across our frontend and backend. You will own features from early product discussions through implementation, testing, release, and ongoing maintenance. You will collaborate closely with Product and Customer Success to understand customer needs and turn them into reliable, maintainable solutions. You will also help us improve and expand our AI-augmented engineering workflows while remaining fully accountable for the quality, security, and architecture of the resulting code. The approximate focus of the role is:
* 45% backend engineering
* 25% frontend engineering
* 20% AI tooling and agentic engineering workflows
* 10% infrastructure and platform engineering What You’ll Do Build and own product functionality
* Design, build, test, and release new frontend and backend features.
* Take end-to-end ownership of your work, including technical design, implementation, testing, documentation, deployment, and maintenance.

* Collaborate with Product during the early stages of feature design.
* Provide both technical and functional input on proposed solutions.
* Work closely with Customer Success to understand customer needs and implementation challenges.
* Translate customer and product requirements into reliable technical solutions. Advance AI-augmented engineering
* Use AI-assisted development tools such as Claude Code, Cursor, or comparable IDE-integrated agents to build, test, document, and review software.
* Work with our existing agentic engineering workflows and help improve and expand them.
* Create and maintain reusable agent skills, contextual instructions, and related patterns that accelerate development and promote architectural consistency.
* Standardize the context provided to coding agents through approaches such as AGENTS.md, skills, and similar mechanisms.
* Maintain strict human-in-the-loop accountability for code quality, security, and architectural decisions.
* Act as the final reviewer of AI-generated output and ensure that it meets our engineering standards. Maintain a high quality bar
* Write clean, reliable, secure, and maintainable code.
* Apply effective testing practices.
* Review code critically, regardless of whether it was written by a human or generated with AI assistance.
* Treat bugs as an immediate priority. We do not knowingly leave defects in the platform: when we identify a bug, we fix it.

* A good understanding of HTTP, OAuth, OpenID Connect, encryption, and API security.
* Experience making data-informed technical decisions and clearly explaining the reasoning and trade-offs behind them.
* Experience writing technical documentation, including Architecture Decision Records.
* Experience implementing integration testing strategies.
* Experience working with component libraries or design systems such as Material UI, styled-components, or comparable technologies.
* An understanding of LLM capabilities and limitations, together with the analytical skills needed to verify and refine AI-generated solutions.
