What do we do? Paddle offers digital product companies a completely different approach to their payment infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we’re a Merchant of Record for our customers. That means we take away 100% of the pain of payment fragmentation. It’s faster, safer, cheaper, and, above all, way better. We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North and serve over 6000 software sellers in 245 territories globally.   The Role: As a Site Reliability Engineer, you’ll be helping to drive our product and engineering department forward, ensuring reliability on different parts of the Paddle platform and helping our Engineers to work better and more efficiently. Paddle SRE team’s role is “Everything SRE”, with a focus on infrastructure, reliability standards, and practices. The SRE team is part of the Platform function. By following this model: * It’s easy to spot patterns and draw similarities between services and projects. * We act as a glue between disparate product teams, creating solutions out of distinct pieces of software. * Enable product engineers to use DevOps practices to maintain user-facing products without divergence in practice across the business. * Define production standards as code and work to smooth out any sharp edges to greatly simplify things for the product engineers running their services. You are empowered to use the right tech for the job. You’ll have the freedom to input into what technology and tooling are used and educate the rest of your colleagues accordingly. As an SRE, we want you to be a driving force of improving and automating how our product teams develop software at all stages of its lifecycle, which we strive to achieve with strong collaboration and communication with our fellow engineers.   Tech Stack: * Go for our new services * PHP Laravel for our Classic system * Aurora MySQL and PostgreSQL for persistent data storage * Docker in production and local development * AWS ECS Fargate for our runtime * AWS SQS for asynchronous message queues * AWS EventBridge for our event bus * Redis for key/value store * Terraform for resource management * Honeycomb, SLOs and OpenTelemetry for our observability needs * Cloudflare for our firewall and DNS server   What you'll do: * Develop and maintain tools to maximise engineering efficiency; such as but not limited to automating deployment infrastructure and database upgrades * Seek out processes that can be improved with automation and have internal Developer Experience as a main driver. Collaborate and enable engineers to do their jobs more efficiently, working with other engineers on a regular basis * Create, maintain and test our system disaster recovery process, including tooling to automate the process * You’ll be able to choose from a selection of AI tools to support day-to-day work (e.g. code generation, investigation, automation, and documentation), and we’ll back sensible experimentation with the right guardrails. * Handle production incidents, author blameless postmortems and enrich operational playbooks and runbooks * Monitoring, alerting, and SLO tracking; hands-on SRE work, not just DevOps-style monitoring * Run performance investigations (load testing, bottleneck analysis) and drive tuning across apps, data stores and AWS. * Own cost optimisation workstreams: right-sizing, autoscaling policies, workload scheduling, storage tiering, and identifying waste across ECS/Fargate, RDS/Aurora, SQS and observability. * Be an advocate of the GitOps methodology   We'd love to hear from you if you: * A software development background, with experience shipping and operating production services, plus strong fundamentals in testing, code review, CI/CD, and debugging. * Have experience working across the AWS ecosystem, partnering closely with AWS Solution Architects and subject-matter experts to design, review, and operate production systems * A curiosity about AI and how it’s reshaping software development. * Collaborative, security-minded, and detail-oriented. We move quickly, so you’ll thrive if you enjoy a fast-paced environment and take pride in doing things the right way. * Knowledge of platform and ops concepts such as networking and Linux administration * Experience working with microservices and distributed systems at scale * Experience with monitoring tools: we use Opentelemetry, Honeycomb, Grafana, Pingdom and Incident.io   Everyone is welcome at Paddle At Paddle, we’re committed to removing invisible barriers, both for our customers and within our own teams.
