About Cantor8

Cantor8 is a global blockchain infrastructure company connecting large institutions and governments to the Canton Network, the first privacy-enabled, interoperable blockchain for regulated financial markets. Founded in 2025 by engineers and researchers from Cambridge, we are a self-funded, distributed team of 18, primarily engineers, building the foundational layer where regulated capital meets on-chain rails. We pride ourselves on absorbing blockchain complexity, enabling institutions to onboard onto Canton in days, and fostering a culture of clarity, control, and long-term reliability.

To bridge the gap between traditional financial institutions and the blockchain by providing secure, compliant, and scalable infrastructure on the Canton Network.

Role Mission

To elevate production reliability for mission-critical payment infrastructure by applying senior Scala engineering expertise to achieve unparalleled system stability and performance on the Canton Network.

This is a pivotal opportunity for a Senior Site Reliability Engineer to own and elevate the production reliability of heavily loaded, mission-critical payment services on the Canton Network. You'll be a hands-on software engineer, diagnosing and resolving production issues directly in the code, then transforming those fixes into robust tooling and automation. Your impact will be immediate and measurable, driving a higher standard of reliability that our institutional clients can confidently rely on, establishing SLOs, error budgets, and blameless postmortems as core engineering practices, and anchoring production response in your time zone.

What You'll Do

Support and elevate the standard of mission-critical, heavily loaded payment services running under real SLAs.
Diagnose and resolve production issues end-to-end, including code modifications, infrastructure configuration adjustments, and performance/network analysis.
Develop reusable tools and automation from one-off fixes to efficiently manage production services.
Establish and champion reliability as a core engineering discipline through SLOs, error budgets, and blameless postmortems.
Provide engineering direction for reliability across the team, defining best practices and implementation strategies.
Anchor production response in your time zone, ensuring rapid and effective incident resolution.

What We're Looking For

5+ years in senior Scala engineering roles supporting mission-critical payments production systems.
Senior Scala individual contributor, focused on software engineering rather than DevOps.

Great to Have

Deep production diagnosis skills, including JVM behavior under load, performance analysis, and network analysis.
Demonstrated real operational responsibility, including on-call duties, incident management, and adherence to SLAs.
Systematic reliability practice, including the habitual use of SLOs, error budgets, and postmortems.
Independent individual-contributor working style, capable of scoping, deciding, and shipping without external blockers.

Bonus Points

Experience building wallet or fiat on/off-ramp infrastructure.
Blockchain or distributed-ledger experience.
Functional programming depth beyond Scala (e.g., Haskell-family languages like DAML).
Fluency in infrastructure and observability tooling, with a developer-first mindset.

Compensation & Benefits

Equity included

Team & Culture

At Cantor8, we build with individuals who deeply understand systems, valuing clarity, control, and long-term reliability. Our culture emphasizes attention to detail, thoughtful system design, and a strong sense of ownership. We foster a collaborative environment where individuals are empowered to think carefully, move with intention, and contribute to lasting solutions, supported by structured work and clear expectations.
