We're hiring a Staff Software Engineer to lead the design and development of high-scale backend systems for our Gaming Integrations team. This is a hands-on IC role focused on building modern, resilient infrastructure and accelerating our adoption of AI across the platform. You'll play a critical part in architectural decisions, mentoring engineers and setting the foundation to up-level and scale the team, while working with cutting-edge tools.

What You’ll Do

  • Own the software lifecycle: define templates, checklists, and playbooks for provider integration—from due diligence and certification to rollout, monitoring, incident response, and deprecation.
  • Unblock delivery: dive into designs/PRs/spikes where needed to remove technical or organizational blockers—without becoming a single point of failure.
  • Shape the roadmap: contribute to multi-quarter technical strategy for integrations, influence the multi-quarter roadmap by identifying platform gaps, vendor risks, and scalability constraints—balancing long-term resilience with short-term delivery.
  • Raise the bar on code & architecture: set patterns for API contracts, reliability, observability, testing, and versioning; reduce complexity and tech debt with clear guardrails.
  • Establish crisp engineering rituals: pragmatic planning, estimation, risk tracking, and stakeholder status; lead critical project reviews and improve signal-to-noise in updates.
  • Be a role model for other engineers: Champion high standards, demonstrate ownership, share knowledge, represent the team with product, compliance, security, data, SRE, and external providers.

What You’ll Bring

  • 8+ years in software engineering, with 3–4 years leading complex backend work where you raised team standards (process, design, testing, documentation).
  • Hands-on with Node.js + TypeScript delivering production services and integrations.
  • Kubernetes in production, running and debugging Node.js services and comfort with modern CI/CD.
  • REST APIs: designing robust, versioned, well-documented contracts.
  • System Design – Proven ability to design scalable, distributed systems
  • Architecture – Experience defining and evolving software architecture at scale
  • Testing – Define and champion test strategies that improve speed, confidence, and reliability across integration pipelines.
  • AI Adoption – Explore and prototype applications of AI to improve observability, automate integrations, or assist developer workflows.
  • Operational maturity: SLIs/SLOs, on-call/runbooks, and blameless incident reviews that drive learning.
  • Stakeholder presence: clear written and verbal communication with technical and non-technical audiences.

Nice to have

  • Experience in gaming/fintech/e-commerce integrations (catalogs, wallets, identity, compliance).
  • Event-driven patterns (e.g., Kafka) and low-latency/high-throughput systems.
  • NestJS – Familiarity with modular, server-side frameworks
  • AWS Services – Experience with services like DynamoDB, Cognito, S3, and Secrets Manager

What Success Looks Like

  • You’ve helped reduce time-to-integrate for new providers from weeks to days.
  • You’ve introduced architectural patterns that improve testability, observability, and reliability at scale.
  • Other engineers seek your input on tough design or debugging problems—and you lift them up without becoming a bottleneck.
  • You’ve made high-quality decisions visible through crisp docs, ADRs, and technical writeups.
