Senior Full-Stack Engineer - AI Cost Visibility

Accountabilities

• Own features end-to-end, from understanding customer problems and defining solutions through design, implementation, release, monitoring, and continuous iteration.
• Take responsibility for the reliability, usability, quality, and measurable business impact of the features you deliver.
• Proactively identify opportunities and propose improvements rather than relying solely on predefined specifications.
• Develop and scale backend services in Go, including APIs, data processing pipelines, and production-grade services.
• Build modern product experiences using TypeScript and React, presenting complex cost and usage data in clear, intuitive, and trustworthy interfaces.
• Design API-first capabilities that can be consumed by both human users and AI agents.
• Work with large volumes of cloud cost and usage data and translate them into useful product experiences and actionable insights.
• Develop a strong understanding of AI spending models, including token and model pricing, inference economics, GPU costs, and the allocation of usage across teams and initiatives.
• Apply FinOps principles and customer needs to product and technical decisions where relevant.
• Use AI tools throughout the engineering lifecycle, including codebase exploration, prototyping, code generation and review, debugging, testing, and documentation.
• Evaluate the effectiveness and limitations of AI-assisted development and establish appropriate quality standards for its use.
• Contribute to thoughtful architecture, design reviews, engineering practices, and technical guardrails that enable rapid but reliable delivery.
• Mentor peers, share knowledge, and help raise engineering standards across the team.
• Collaborate effectively in a distributed environment and contribute to product decisions in a market characterized by significant ambiguity and rapid change.

Requirements:

• 7+ years of professional software engineering experience, including experience building and operating multi-tenant SaaS products in production.

• Comfortable working across the full technology stack, with the ability to take a feature from data model and backend services through to the user interface.
• Experience developing on public cloud platforms, preferably Google Cloud Platform, with AWS or Azure experience also relevant.
• Working proficiency in SQL and experience working with analytical data stores such as BigQuery.
• Strong product-oriented mindset, with an ability to understand why something should be built and assess whether it delivers value for users.
• Demonstrated experience using AI tools across the software engineering workflow and the ability to articulate their practical benefits and limitations.
• Strong understanding of software engineering practices, design patterns, architecture, scalability, reliability, and maintainability.
• Ability to provide technical direction and establish strong engineering practices for other team members.
• Comfortable working with ambiguity and rapidly changing priorities, with the ability to identify the right problems to solve rather than simply implementing predefined solutions.
• Excellent written and verbal English communication skills.
