Senior Full-Stack Kotlin Engineer (Kineto)

Описание вакансии

Kineto is a next-generation platform that enables creators, educators, and small businesses to generate, deploy, and operate fully functional AI-powered web applications – instantly and at scale.

It combines LLM-driven code generation, multi-tenant Postgres (Neon), dynamic hosting (GKE and Knative), automated deployments (Flux), analytics, billing, and a seamless chat-based UX to make software creation accessible to everyone.Our team is growing rapidly, and we’re seeking an experienced Kotlin engineer who can work across our stack, help shape the architecture, and lead major platform initiatives.

What you’ll do

Platform and backend engineering

• Design, implement, and evolve Kotlin and Spring Boot microservices that power generation, hosting, deployments, billing, and analytics.
• Build resilient distributed systems running on GKE, Knative, Flux, Helm, Terraform, and Terragrunt.
• Architect and optimize multi-tenant data models on Neon and Postgres, including aspects like tenant isolation, branching strategies, and safe schema migrations.
• Implement high-performance features using coroutines, structured concurrency, gRPC and HTTPAPIs, SSE and WebSockets, and message queues.

Full-stack development

• Build user-facing features for the Kineto app builder, including dashboards, analytics, editors, session views, run logs, and the billing UI.
• Work across React and TypeScript frontends, integrating with backend APIs, remote configuration, analytics, and credit and billing systems.
• Contribute to the component library, UX flows, and developer tooling that enable the creation and management of thousands of apps.

Operational excellence

• Drive performance tuning across the platform (GC configs, container resources, distributed locks, and caching strategies).
• Solve real operational challenges such as scale to zero, cold starts, autoscaling, build farm performance, and queue backpressure.

AI-powered app generation

• Build and improve the LLM-based generation pipeline that produces thousands of Node.js, Kotlin, and Spring Boot applications.
• Design entropy-safe, cache-friendly templates and generation flows that minimize build times, reduce costs, and improve reliability.
• Collaborate on prompt design, safety layers, and deterministic generation for reproducible deployments.

Technical leadership

• Own major architectural roadmap items, including multi-region deployments, advanced billing, secure tenancy, and preview environments.
• Mentor other engineers, review complex changes, and raise the engineering quality in the team.
• Collaborate with product, design, and infrastructure teams to define the long-term vision for the platform.

We’d be glad to have you on our team if you:

• Have 5 or more years of experience building commercial software in Kotlin, Java, Swift, or similar languages. Bonus points for experience with cross-platform frameworks and iOS and Android app development.
• Have a solid grasp of algorithms, data structures, concurrency, and design principles for large-scale, maintainable codebases.
• Have proven expertise or a strong interest in AI-assisted development, prompt engineering, or ML-based code generation workflows.
• Thrive in cross-functional teams across time zones and technical domains, and excel at communicating complex ideas clearly.
• Are always looking for ways to push the boundaries of what software development can be.
• (Bonus) Are familiar with Compose Multiplatform, building KMP libraries or frameworks, or have experience in IDE/plugin development.
