New York City, NY

About Hashgraph:

Hashgraph is a fast-growing software company committed to supporting, developing and servicing Hedera, an open source, proof-of-stake platform. Hedera is EVM-compatible and has been specifically built to meet the needs of enterprise and web3 applications, which require speed, security, stability and sustainability. Hedera's public network is governed by industry-leading organizations, spanning 11 sectors and 14 regions who oversee the development and direction of the decentralized platform.

The role:

We are hiring a Staff Software Engineer - CI/CD & Release Engineering to architect and scale the systems that power software delivery across Hashgraph's internal and open-source platforms. This role exists because our engineering organization is operating increasingly complex distributed systems across multiple products, environments, and release streams. We need a senior technical builder who can design reliable, scalable, and developer-friendly release infrastructure that enables engineering teams to ship quickly, safely, and repeatedly at production scale. You will help establish the foundation for how software is built, tested, released, deployed, and observed across the company — improving engineering velocity while strengthening reliability and operational confidence.

In this role, you will:

  • Architect and evolve scalable CI/CD systems that support complex multi-product release workflows across internal and open-source platforms
  • Design and build developer tooling, deployment automation, and release orchestration systems using technologies such as GitHub Actions, Kubernetes, and cloud-native infrastructure
  • Lead the engineering strategy for build pipelines, artifact management, release governance, and deployment reliability
  • Improve developer experience by reducing friction in build, test, deployment, and operational workflows
  • Build and maintain highly reliable Kubernetes-based infrastructure powering release automation and engineering productivity systems
  • Drive observability and operational excellence across release systems through metrics, monitoring, and performance instrumentation
  • Partner closely with Platform Engineering, DevOps, Security, Program Management, and Product Engineering teams to align release infrastructure with business and technical priorities
  • Serve as a senior technical leader and multiplier within the organization through architecture guidance, mentorship, and operational rigor

What success looks like in 6-12 months:

  • CI/CD systems are highly reliable, scalable, and capable of supporting rapid multi-product releases with minimal operational overhead
  • Engineering teams ship software faster with improved deployment confidence and reduced release friction
  • Build and release infrastructure is standardized, observable, and repeatable across products and environments
  • Deployment automation significantly reduces manual operational effort and release risk
  • Release engineering becomes a strategic enabler for engineering throughput, platform reliability, and product delivery velocity

What you bring:

Core capabilities:

  • Strong systems thinking with the ability to design scalable engineering infrastructure from first principles
  • Deep ownership mentality with a bias toward automation, reliability, and operational excellence
  • Strong communication and cross-functional collaboration skills across engineering and business stakeholders
  • Ability to balance strategic architectural thinking with hands-on execution
  • Proven ability to operate effectively in fast-moving, high-autonomy engineering environments

Functional expertise:

  • 7+ years building and operating production-grade software engineering infrastructure or CI/CD platforms
  • Deep experience designing and operating CI/CD systems using tools such as GitHub Actions and/or GitLab CI
  • Strong experience with Kubernetes, Docker, and cloud-native infrastructure patterns
  • Strong programming and automation experience in one or more of: Kotlin, Java, Go, Python, or Bash
  • Experience building scalable build, test, release, and deployment automation systems
  • Experience with modern build systems and dependency management tools such as Gradle, Maven, or NPM
  • Experience operating engineering infrastructure within AWS and/or Google Cloud Platform environments
  • Experience designing observability and monitoring solutions using tools such as Grafana and related telemetry systems
  • Strong understanding of release management strategy, deployment safety, and operational reliability practices
  • Experience writing high-quality technical documentation, engineering standards, and operational processes

Nice to haves:

  • Experience supporting large-scale open-source software development workflows
  • Experience with distributed systems, blockchain, or decentralized infrastructure technologies
  • Experience optimizing build performance, release throughput, or engineering productivity at scale
  • Expertise in Golang and advanced shell automation

This role is ideal for someone who enjoys going deep into understanding both the technical and business context behind problems, not just implementing solutions mechanically. We value engineers who are curious, proactive, and driven by learning - people who enjoy experimenting, challenging assumptions, and troubleshooting complex systems until the root cause is fully understood. As a Staff Backend Engineer, you will provide technical leadership across architecture, engineering practices, and platform evolution while remaining hands-on when needed. You will help teams make better technical decisions, raise engineering standards, simplify complex systems, and create solutions that balance business needs with long-term platform health. We're looking for someone who is comfortable working in ambiguity, treats failure as an opportunity to learn, welcomes constructive feedback, and leads through collaboration, ownership, and execution rather than authority. ABOUT YOUR FUTURE PLATFORM TEAM We build and operate a critical backend platform that generates, validates, and distributes customer-facing offers across multiple markets in real time. The system sits at the intersection of pricing, configuration, compliance, and localization - where milliseconds matter, correctness is non-negotiable, and small mistakes can have large-scale impact. Our systems apply complex configuration and licensing rules, handle market and event-level blocking, manage multi-language localization, and transform raw pricing data into customer-ready offers consumed across the ecosystem. We process high-throughput event streams, deal with constantly changing data, and solve problems that require both strong engineering fundamentals and deep domain understanding. Success means no incorrect or missing offers in production, near real-time reflection of pricing and configuration changes, fully compliant offers across jurisdictions, and seamless multi-language experiences for customers.
