We’re looking for a Staff Software Engineer to own the systems that determine how customers adopt, upgrade, and pay for Helius. This work sits at the intersection of product, engineering, and revenue. You’ll design clean, reliable foundations for billing, metering, pricing, and entitlements, then build the flows that make them intuitive for customers. The role is broad, high-ownership, and requires strong technical depth paired with sharp product instincts.

• Design and build monetization-critical systems, including billing, metering, and entitlements

• Own backend logic powering free trials, upgrades, usage-based pricing, quotas, and upsell flows

• Collaborate with the Full-Stack team on features that directly impact revenue and adoption

• Ensure correctness, reliability, and auditability across pricing and billing systems

• Drive long-term architecture for metering, quota enforcement, and product enablement

• Move quickly, make strong product calls, and keep systems simple and resilient

• 8+ years of backend/full-stack engineering experience with scalable APIs or distributed systems

• Experience building & maintaining billing systems in high-growth environments

• Proficient with database design, microservice architecture, and strongly-typed programming languages (e.g. Golang)

• Strong instincts around correctness, data integrity, and operational reliability

• Ability to connect engineering decisions to real revenue outcomes

• Comfort owning broad, ambiguous problem areas and driving clarity

• Frontend development experience (React, TypeScript, and Next.js preferred)

• Prior startup and/or web3 experience

• Solana development experience

• Understanding of web security best practices

• High-impact work: Your code will power applications used by millions across the Solana ecosystem, including Coinbase, Jupiter, and Phantom

• Serious engineering: Build fast, reliable systems and user experiences across distributed infra, high-throughput backends, and modern frontend stacks

• Ownership & growth: Lead critical initiatives, influence architecture and product direction, and take on more responsibility as the company scales

• Remote-first flexibility: Work where you’re most effective with a flexible, fully distributed team

• Competitive comp & perks: Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel

• Mission-driven team: Join ambitious builders who move fast, take ownership, and are shaping the future of decentralized apps.
