About Zenith

Zenith is the first Ethereum extension for the Canton Network, enabling participants to launch fully Ethereum-compatible execution environments that integrate directly with Canton's privacy, compliance, and settlement infrastructure. With Zenith EVM, teams deploy their Ethereum applications onto Canton using familiar tooling — Solidity, Hardhat, Foundry, and MetaMask — while Zenith Stack lets institutions run a fully customized blockchain environment without building or maintaining the infrastructure themselves. Engineered for high-frequency institutional finance, these environments deliver 100,000+ TPS and sub-second finality, giving institutions and builders the foundation for interoperable, compliant, and scalable financial systems on Canton. Support for further environments, beginning with a Zenith SVM for Solana applications, is on the way.

Operating at the intersection of DeFi and TradFi, Zenith connects Ethereum's builders and liquidity with the institutional capital flowing through Canton — bringing consumer blockchains and institutional-grade ledgers together to modernize global finance.

Our team combines decades of experience across blockchain infrastructure, capital markets, and venture innovation. Zenith is a registered Super Validator within Canton's Global Synchronizer — one of 50+ Super Validators securing the network — extending the ecosystem to deliver institutional trust, compliance, and scalability to the next generation of digital assets.

What you’ll do

This is a high-impact, hands-on SRE leadership role for a senior engineer who can own Zenith’s infrastructure systems today and build the operational foundation for a world-class SRE team tomorrow. You will lead all reliability, performance, and operational functions across Zenith’s internal systems, Zenith Stack environments, and validator infrastructure.

Ideally, you have built and are currently managing systems that simply cannot have any downtime. We are looking for someone who can initially build our system reliability single-handedly and later on lead a team to ensure our clients are serviced at all times and that the system is further refined.

In this role, the following aspects are essential:

• Own production reliability: Ensure strong operational reliability and resilience practices while partnering with engineering teams responsible for software quality.
• Manage and evolve cloud environments: Build, automate, and maintain scalable cloud systems supporting multi-layered blockchain execution and off-chain runtimes.
• Build SRE processes: Define and implement incident response, observability, monitoring, alerting, on-call rotation, runbooks, and reliability KPIs.
• Lead operational excellence: Establish systems for versioning, release management, configuration, secrets, environment orchestration, and reproducibility.
• Enable client Zenith Stack deployments: Work closely with engineering and product teams to support the deployment, scaling, and reliability of client-tailored Zenith Stacks.
• Collaborate on protocol operations: Partner with core engineering to support validator operations, network participation, upgrades, and secure infrastructure.
• Drive automation: Identify manual inefficiencies and replace them with robust automation for provisioning, deployment, and system testing.
• Build & lead the future of SRE: As Zenith scales, grow and mentor a high-performing SRE team that supports institutional-grade demands.
• Act as the operational technical expert: Provide hands-on leadership across infrastructure decisions, cloud architecture, and reliability challenges.

To join our team, you should be excited to

• Take full ownership of Zenith’s reliability posture from day one — designing processes, systems, and tools that scale with global institutional usage.
• Work deeply with engineering, product, and external partners to ensure Zenith Stack deployments and client environments run seamlessly.
• Shape the operational foundation for an infrastructure company operating at the intersection of TradFi, blockchain and EVM.
• Build an SRE practice from the ground up, transitioning from hands-on contributor to a team leader as the organization grows.
• Thrive in an environment where autonomy, ownership, and precision matter.

Minimum qualifications

• Previous track record of being the character with the most responsibility of the site reliability of your then company. Ideally you have maintained systems solo, but also built a team before or led one.
• Previous experience building or leading an SRE team.
• 7+ years in site reliability engineering, DevOps, platform engineering, or infrastructure-focused software engineering.
• Proven experience owning reliability, uptime, and operational excellence for distributed systems or mission-critical infrastructure.
• Deep understanding of Linux systems, networking, cloud platforms (AWS/GCP/Azure), containerization, and infrastructure automation.
• Previous expertise working with kubernetes as this is a non-negotiable piece of the infrastructure.
• Hands-on experience building monitoring, observability, performance, alerting, incident response systems, and on-call processes.
• Strong knowledge of:
• Infrastructure-as-Code (Terraform, Pulumi, etc.)
• CI/CD systems
• Secrets management
• Logging & metrics stacks
• Kubernetes
• Ability to design and execute scalable, fault-tolerant architectures with a strong automation mindset.
• Comfortable coordinating with engineering teams and working cross-functionally with product and protocol teams.
• Based in Europe (strongly preferred), with the ability to operate across global time zones.

Bonus points

• Experience operating infrastructure for blockchain networks, validators, L1/L2 systems, consensus clients, or distributed ledgers.
• Familiarity with EVM-based blockchain architectures.
• Experience deploying and maintaining environments that handle high throughput, low latency, or cryptographic workloads.
• Background supporting enterprise clients, regulated environments, or high-availability financial systems.

Zenith culture

At Zenith, we only do first-class business, and we do it in a first-class way.

We operate with ambition, precision, and mutual respect, always playing the long game because we’re in the relationship business. We believe in the future, and we bet the firm on it.

We’re a remote-first team (meeting in person two to four times a year) that values both excellence and humanity. We celebrate the good times, play to win, and never lose sight of the team behind every success.

Some of our guiding principles:

• Default to trust, empathy & respect. We assume good intent and independent capability.
• Authority to ideas, not people. Great ideas can come from anyone. We debate based on merit, not hierarchy.
• Manage yourself. Initiative and ownership drive us further than micromanagement ever could.
• Meetings are tools, not habits. We keep communication lean, async, and effective.
• Celebrate small wins. Momentum matters, and recognition keeps it alive.
• Feedback fuels growth. Give it, receive it, and improve together.
• Work-life fit. We fit work into life, not the other way around.
• Rest is part of performance. Sustainable excellence requires balance.

At Zenith, you’ll architect and lead the systems that power the institutional blockchain era turning cutting-edge engineering into the trusted infrastructure of global finance.
