Staff Product Engineer, Backend (Go + Java)

• Turn usage into revenue. We charge based on data, which means we need rock-solid metering. You'll build the systems that count every event, sync it with payment providers, and ensure invoices are accurate down to the cent.
• Drive reliability and risk management. You will own the reliability of the platform, proactively identifying risks before they become incidents. You'll foster a security-first culture and ensure our monitoring efforts are world-class.
• Provide mentorship and improve the process. You will define the standards for code quality, testing, and observability. You act as a force multiplier-mentoring others, reviewing PRDs to ensure technical feasibility, and simplifying complex technical designs to align with product goals.

What Success Looks Like (and How You'll Get There):

• Within 1 week, you'll have shipped your first piece of production ready code.
• Within 3 months, you'll extend our billing system and provide more transparency into usage and help our customers to maintain full control over observability cost.
• Within 6 months, you'll establish new architectural patterns (Go) in our billing solution. You will be actively mentoring engineers across the organization, helping them level up their understanding of our billing architecture and integration with marketplace and CRM tools.
• Within 12 months, you will be a technical authority for our backend strategy, having successfully guided the team through major scaling challenges. You'll have played a key role in shaping the product roadmap by bridging the gap between technical constraints and customer needs.
