Senior DevOps Engineer - Embedded Payments

About the opportunity

Join our Embedded Payments team as a DevOps Engineer to make a real impact every day. We say that because we know that every conversation we have, every pipeline we build and every system we automate is another opportunity for us to elevate everyday life experiences for our customers and the people and communities they serve.

Reporting into the DevOps Engineering Manager, you'll help us build and scale the infrastructure behind our cloud-native payment orchestration platform that processes significant transaction volume across multiple Xplor brands. You are passionate about building reliable, secure systems and the automation that keeps them running smoothly while maintaining engineering best practices. You think about infrastructure end-to-end, from CI/CD pipelines and infrastructure as code down to monitoring, alerting, and incident response. You're comfortable owning the platform that everything runs on and collaborating closely with backend, frontend, QA, and engineering teams to ship and operate high-quality software.

Our Tech Stack

Cloud

AWS (ECS, Lambda, RDS/Aurora PostgreSQL, API Gateway, SQS, EventBridge, Cognito, KMS, VPC)

Infrastructure as Code

Terraform

CI/CD

Bitbucket Pipelines

Observability

SigNoz, Grafana, CloudWatch

Performance & Load Testing

k6

Security & Compliance

PCI DSS, AWS-native controls

Application stack supported

Node.js services, React frontends

Responsibilities & Duties

Design, build, and maintain AWS infrastructure using Terraform, with attention to scalability, cost, and PCI-scoped network segmentation

Own and evolve the observability stack — SigNoz for distributed tracing and metrics, Grafana for dashboards, structured logging — so engineers can answer "what's happening in production" without paging you

Build and maintain CI/CD pipelines in Bitbucket Pipelines, including deployment guardrails, automated rollback strategies, and environment promotion workflows

Design and run performance and load tests with k6 or other custom tools as needed, establish baseline benchmarks, and partner with engineering to address bottlenecks before they reach production

Participate in on-call rotations, lead incident response for infrastructure issues, and drive postmortems that produce durable fixes

Define and track SLOs, error budgets, and operational KPIs for payment-critical services

Improve deployment velocity and safety — faster pipelines, better preview environments, safer migration tooling

Partner with security and compliance to maintain PCI DSS posture, support audits (Armanino/Vanta), and codify controls

Manage cost and capacity across AWS — right-sizing, reserved capacity strategy, and identifying optimization opportunities

Use AI-assisted tools effectively to accelerate infrastructure work without compromising review quality or security posture

What would make me a good candidate?

We are looking for curious and empathetic people. We also love to hear from people who are motivated by meaningful work, resonate with our core values, have a positive outlook, are comfortable with ambiguity and thrive working in an ever-evolving and complex environment. We are inspired by meeting big-picture thinkers and doers, people who can be both tactical and strategic, aim high and put people first in everything they do.

You'll need

5+ years of professional DevOps, SRE, or Platform Engineering experience, with a Computer Science/Engineering degree or equivalent

Strong hands-on AWS experience across compute (ECS, Lambda), networking (VPC, security groups), data (RDS/Aurora), and event-driven services (SQS, EventBridge)

Production Terraform experience — module design, state management, drift handling, and multi-environment patterns

Experience operating an observability stack in production; familiarity with SigNoz, Grafana, or comparable tools (Datadog, New Relic, Prometheus)

Experience designing and running load tests with k6 or comparable tools (JMeter, Gatling, Locust)

Experience building and maintaining CI/CD pipelines (Bitbucket Pipelines, GitHub Actions, CircleCI, or similar)

Strong shell scripting ability or similar in a scripting oriented language (Python, Go, etc...)

Ability to read and understand back end and and front end code in order to implement infrastructure more effectively

Solid understanding of networking fundamentals such as sockets, routing, load balancing, SSL/TLS encryption, tunneling, firewalls/security groups, etc...,

Understanding of access control and identity management (IAM, OIDC, Cognito, OAUTH in general or similar)

Comfort leading incident response and writing postmortems that drive systemic improvement

Fluency with AI-assisted development tools (Claude Code, Cursor, Copilot, etc.) and an articulate point of view on where they help and where they don't

Comfortable working on a 100% remote team and operating independently within an agile group

It would be great if you also have

Experience operating PCI-compliant or otherwise regulated environments

Experience with payments infrastructure or other high-availability transactional systems

Familiarity with Vanta or comparable compliance automation tooling

Experience tuning PostgreSQL for high-throughput workloads

Exposure to KMS-based cryptography, secrets management, and key rotation strategies

Experience with chaos engineering or game-day exercises
