Staff Software Engineer, Rapid Innovation

Keeper Security is a cybersecurity software company protecting organizations and individuals from cyber attacks. The Staff Software Engineer will join the Rapid Innovation team to turn ambiguous, high-priority ideas into working software, spanning backend services, web applications, desktop software, security products, developer tooling, and AI-enabled capabilities. The role involves shaping architecture, building prototypes, validating concepts, and transitioning successful initiatives to long-term engineering teams.

Responsibilities:

• Rapidly design and build working software for new product concepts, technical experiments and strategic initiatives
• Take loosely defined ideas from concept through functional implementation with minimal product or technical specification
• Define architecture and technical direction for early-stage projects while making pragmatic tradeoffs around speed, security and scalability
• Work across backend, frontend, desktop, platform, integration and infrastructure technologies depending on project needs
• Develop backend services and APIs using Java and other appropriate technologies
• Build modern user experiences using JavaScript, TypeScript, React and related technologies
• Evaluate unfamiliar technologies, frameworks, APIs and codebases and become productive quickly
• Integrate AI models, APIs and emerging AI capabilities into software when appropriate, partnering with Keeper’s AI and Machine Learning teams for specialized expertise
• Identify technical risks, validate feasibility and determine whether concepts are ready to move toward productization
• Create enough technical structure, documentation and architecture guidance to support clean handoff to long-term engineering owners
• Mentor engineers and raise technical standards through design reviews, technical guidance and hands-on collaboration
• Collaborate directly with the CTO, Engineering leaders, Product teams and subject-matter experts across Keeper
• Use AI-assisted development tools such as Claude, ChatGPT, GitHub Copilot or similar platforms extensively to accelerate research, coding, debugging, testing and technical exploration

Requirements:

• 9+ years of professional software engineering experience with demonstrated breadth across multiple areas of software development
• Strong software engineering fundamentals and the ability to design and build complete applications, services and integrations
• Demonstrated experience leading technical architecture and execution for complex software projects
• Proven ability to independently take ambiguous or minimally defined ideas from concept through functional implementation
• Strong backend development experience, preferably with Java and modern service-oriented architectures
• Experience building modern frontend applications using JavaScript or TypeScript and React or similar frameworks
• Experience designing and integrating APIs, backend services, databases and third-party technologies
• Strong debugging and problem-solving skills across unfamiliar systems and codebases
• Demonstrated ability to learn new programming languages, frameworks and technical domains quickly
• Ability to make effective technical tradeoffs when speed and experimentation are more important than long-term production architecture
• Strong technical curiosity and a demonstrated history of experimenting with, building or exploring new technologies
• Proven ability to influence technical direction and mentor engineers without relying on formal people-management authority
• Experience using AI-assisted development tools to accelerate software engineering, research, debugging and prototyping
• Ability to clearly communicate technical findings, architecture decisions and handoff requirements to other engineering teams
• Bachelor's degree in Computer Science, Engineering or a related field, or equivalent practical experience
• Experience participating in hackathons, engineering competitions, open-source projects, technical side projects or similar build-focused environments
• Experience working at an early-stage startup, innovation lab, prototyping team or other environment with limited structure and rapidly changing priorities
• Experience with Python and/or Rust
• Experience integrating large language models, AI APIs, agents or AI-enabled workflows into software
• Experience building cybersecurity, developer tooling, desktop, infrastructure or platform products
• Experience taking a product from initial concept or prototype through technical validation and handoff
• Broad technical experience spanning multiple languages, frameworks, platforms or areas of software engineering
