Remote Senior NA Artificial Intelligence Senior Software Engineer Java Kotlin Scala SQL Kafka Cursor Rust Terraform

Requirements

• 5+ years building production-grade backend systems in Java, Kotlin, or Scala • A product mindset — you care about why you’re building something, not just what you’re building • Experience designing and operating high-scale, distributed systems • Strong SQL fundamentals — schema design, indexing strategies, query optimization, and performance tuning • Comfort working across multiple technologies and services, even outside your primary language • Solid understanding of RESTful APIs and microservices architecture • Familiarity with messaging systems (e.g., Kafka) and asynchronous processing patterns • Practical use of AI-assisted development tools (Cursor, ChatGPT, LLM copilots) to improve speed and quality

Responsibilities

• Design, build, and operate high-throughput Java/Kotlin services that power our ad server and creative delivery pipelines • Own systems end-to-end — from API design and ingestion flows to transformation, caching, and global delivery • Work across the stack when needed (Rust services, Kafka streams, Terraform, relational databases) to solve the right problem with the right tool • Improve performance, observability, and resiliency of critical production systems running at scale • Partner closely with Product and Project leads to translate business needs into scalable technical solutions • Contribute to architectural decisions that shape the future of our creative platform • Raise the engineering bar through thoughtful code reviews, design discussions, and pragmatic best practices • What success looks like • You own and evolve high-scale services within our ad serving and creative delivery platform, ensuring low-latency, high-availability performance under sustained traffic. • You design and ship scalable solutions that measurably improve system reliability, throughput, or cost efficiency. • You proactively identify architectural risks and technical debt, driving improvements before they impact customers or operations.

Benefits

• 100% remote within the US • Flexible vacation policy • Annual vacation allowance for travel related expenses • Three-day weekend every month of the year • Competitive compensation • 100% healthcare coverage • Flexible Spending Account (FSA) for dependent, medical, and dental care • Access to coaching, therapy, and professional development • Our recruiters will always reach out using an email address ending with @mountain.com OR @mntn.com. If you’re contacted by someone without that address and they mention a Reference Code (which we never use), then that ain’t us folks. Tell those trolls to take a hike–you’re waiting to climb a MNTN.
