About walllet.com

walllet.com builds products used to receive, hold, spend and move money.

The visible interface is only one part of that system. Behind it are cloud services, partner integrations, identity and access controls, payment events, monitoring, audit records, deployment pipelines and operational procedures.

Reliability problems in financial products affect more than convenience. A delayed event can leave a customer uncertain about a transfer. Weak observability can slow incident resolution. Poor access controls can create unacceptable security exposure.

Our infrastructure team works to make these systems secure, observable and recoverable.

About the role

We are hiring a Senior DevOps Engineer to improve the infrastructure, delivery systems and operational reliability behind walllet.com.

You will design and operate cloud environments, deployment pipelines, monitoring, secrets management, access controls, backup systems and incident-response tooling.

You will work with application engineers to improve how services are built, deployed and diagnosed. You will also help define reliability standards for systems that connect to financial and blockchain infrastructure.

This role requires practical engineering judgement. We need someone who knows when automation reduces risk, when an abstraction hides important behaviour and when a manual control is still appropriate.

What you’ll be doing

• Designing, operating and improving production cloud infrastructure

• Building and maintaining CI/CD pipelines with controlled, auditable deployments

• Managing infrastructure through code

• Improving logging, metrics, tracing, alerting and operational dashboards

• Defining service-level indicators and reliability targets with engineering teams

• Automating environment provisioning, configuration and routine operational tasks

• Strengthening identity, access, secrets and key-management practices

• Supporting secure networking and service-to-service communication

• Improving backup, restoration and disaster-recovery procedures

• Participating in incident response and writing useful post-incident reviews

• Investigating performance, availability and deployment problems

• Improving dependency, container and infrastructure vulnerability management

• Supporting partner-integration monitoring and reconciliation workflows

• Reducing unnecessary infrastructure cost without weakening reliability

• Documenting runbooks, ownership and escalation paths

• Coaching engineers on production readiness and operational responsibility

What you’ll need

• At least 6 years of infrastructure, DevOps, SRE or platform-engineering experience

• Strong experience with at least one major cloud platform

• Production experience with containers and orchestration

• Strong knowledge of infrastructure-as-code practices

• Experience building and maintaining CI/CD systems

• Working knowledge of Linux, networking, DNS, TLS and HTTP

• Experience implementing observability across distributed services

• Experience with secrets management and least-privilege access

• Ability to investigate incidents across application and infrastructure layers

• Experience with backup, recovery and resilience testing

• Ability to write scripts or tools in a relevant programming language

• Strong written documentation and remote collaboration skills

• Willingness to participate in a defined on-call or incident-response rotation

Nice to have

• Experience operating infrastructure for fintech, payments or regulated products

• Familiarity with AWS, Kubernetes, Terraform and GitHub Actions or comparable technologies

• Experience with event-driven systems and financial reconciliation

• Experience with blockchain nodes, RPC providers or wallet infrastructure

• Knowledge of PCI DSS, SOC 2, ISO 27001 or comparable control frameworks

• Experience with security automation and policy-as-code

• Familiarity with database reliability and high-availability design

• Experience supporting mobile and web backends at scale

• Experience working with third-party banking or payment APIs

What we offer

• Meaningful ownership and direct influence on the product

• A thoughtful, low-ego team that values clear communication

• Flexible work with time for focused craft and collaboration

• The chance to help build financial tools for a global customer base
