Who We Are

Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun, the largest memecoin launchpad in production today.

~$1B daily volume. Low latency, high throughput, constant load.

• Own the most critical and complex backend systems, directly writing and shipping production code across core services
• Lead the design and implementation of high-scale distributed systems that power real-time, high-throughput workloads
• Set technical direction for foundational backend architecture while remaining deeply involved in execution
• Make principled architectural decisions that balance iteration speed with long-term scalability, resilience, and maintainability
• Drive multi-service initiatives that cut across storage, compute, APIs, and blockchain infrastructure
• Anticipate scaling constraints and correctness risks before they surface, proactively designing durable solutions
• Establish patterns and standards for observability, reliability, performance tuning, and operational excellence
• Raise the engineering bar through design reviews, RFCs, and direct mentorship, influencing through technical depth and clarity of thinking
• Act as a technical anchor during high-pressure incidents, ensuring systems remain stable under load
• Improve internal developer velocity by evolving tooling, CI/CD pipelines, and service abstractions

• 10+ years of backend engineering experience, with multiple cycles of building, scaling, and operating distributed systems in production
• Proven track record of owning foundational backend architecture in high-growth or high-scale environments
• Deep expertise in Rust, Go, or Type Script, with strong systems-level intuition
• Strong understanding of distributed systems design: consensus, failure modes, replication, consistency models, and performance tradeoffs
• Extensive experience with database design and data modelling, including complex tradeoffs around consistency, latency, and durability
• Comfortable owning ambiguous, cross-cutting problems that span multiple services and teams
• Recognised as a go-to technical authority by senior engineers and peers
• High-agency and execution-focused. You shape direction by building
• Crypto experience is a plus

• We work in person
• Hours can be long and unconventional
• The pace is intense
• Expectations are high, and impact is immediate
• Working at Baton is not for everyone

• Unmatched ownership and autonomy
