Descripción del empleo

About the Team The Infrastructure team at Spendesk builds the tools, systems, and internal products that empower every engineering team to move faster and more safely. We are transforming traditional infrastructure into a developer-facing platform focused on enablement, automation, and scalability . We own CI / CD platform (ArgoCD and Github Actions), secrets management, observability tooling, infrastructure provisioning, and developer workflows. Our work is foundational to the productivity and reliability of the entire product organization.

About The Role

• As a Senior Platform Engineer , youʼll help define and deliver the next generation of internal tooling and infrastructure at Spendesk. Youʼll be hands-on in designing scalable systems, collaborating with engineering peers, and productizing shared services used by dozens of engineers across the company.

Mission : At Spendesk, Platform Engineering isn’t just about keeping the lights on, it’s about building the foundation for scale. We create the internal products that make every engineer faster, safer, and more autonomous. Our mission is to turn complexity into simplicity , manual toil into automation , and infrastructure into a platform that drives innovation.

What Youʼll Do

As a Senior Platform Engineer at Spendesk , youʼll help shape the foundation that every engineering team builds on. Youʼll work hands-on with Kubernetes, Go, and AWS to create scalable, reliable, and developer-friendly systems that power our internal platform.

Hereʼs how youʼll make an impact :

Design, build, and maintain core infrastructure services including provisioning workflows, service orchestration, and deployment automation using Kubernetes, Go, and cloud-native tools

Own and evolve our CI / CD platform , improving performance, reliability, and usability, with a focus on fast feedback, secure secrets handling, and smooth rollback support

Own Infrastructure Service Orchestrator that allow product teams to spin up production-ready services in minutes with consistent tooling, observability, and security baked in

Contribute to the technical rollout of our Service Orchestrator , a new internal product aimed at simplifying infrastructure provisioning across squads

Improve our observability tooling and incident response workflows , building custom dashboards and refining alerting systems to reduce noise and improve reliability

Partner closely with product engineers and EMs to identify recurring friction in development workflows and turn those into reusable, documented platform solutions

Take technical ownership of key platform domains , such as secrets management, infrastructure as code, monitoring pipelines, or cost visibility tooling

Champion internal adoption of platform capabilities by writing excellent documentation, creating onboarding guides, and supporting team usage through async support and office hours

Migration of legacy infrastructure components (such as : Secret management tool, Permission management tools) to new platform tooling mainly based on K8s resulting in devOps culture mindset ( You build it, You own it )

Participate in our regular on-call rotation (off-hours) & firefighting (on-hours) , using that insight to continuously reduce toil through automation, self-healing systems, and smarter alert routing

Who you are

A strong individual contributor with a platform mindset —someone who enjoys solving developer pain with elegant, scalable systems and takes pride in enabling others to move faster.

Youʼre a fit for this role if you have :

7+ years of engineering experience , with a strong track record in DevOps, infrastructure, or platform roles supporting multiple engineering teams

Hands-on experience with Kubernetes in production environments , including designing and debugging containerized services at scale

Fluency in Go (Golang), Bash & Python , you’ve built tooling, services, or operators that run reliably in production

Proficiency with AWS and a solid understanding of Infrastructure-as-Code using Terraform or a similar tool

Experience building internal tooling or platforms used across multiple teams —bonus if youʼve owned adoption, documentation, or support

A bias for automation, you replace playbooks with code and eliminate toil wherever possible

A product mindset, you empathize with your users (other developers), gather feedback, and treat internal systems like customer-facing products

Strong written and verbal communication skills, clear documentation and async updates are second nature to you

A love for clean abstractions, scalable systems, and improving developer workflows

Fluent in English (spoken and written) — itʼs our business language.

Nice to have

Familiarity with CI / CD pipeline design , especially trunk-based workflows, rollback strategies, and secure secret handling

Hands-on work with monitoring and observability stacks (, Grafana, Prometheus, Datadog)

Knowledge of SLOs, alerting strategy , and incident tooling (, PagerDuty, alert routing)

Exposure to cost visibility and optimization tooling within AWS or other cloud platforms

Comfort operating in regulated or compliance-sensitive environments (, fintech, GDPR

Contributions to open-source DevOps or platform tooling

Familiarity with platform metrics frameworks like DORA, internal NPS, or developer satisfaction surveys

Proven ability to influence cross-team technical initiatives or onboard other engineers to shared tools

Experience navigating fast-growing SaaS or product engineering orgs with 50+ developers
