DevOps Engineer — SendX & SendPost
At SendX and SendPost, we build high-scale email infrastructure, marketing automation systems, APIs, and developer-focused communication products. We are looking for a hands-on DevOps Engineer who enjoys going deep into systems, performance, observability, automation, and infrastructure reliability.
This is not a “dashboard-only” DevOps role. We want someone comfortable working close to the OS, networking stack, containers, queues, databases, and application runtime internals.
What You’ll Work On
- Build and maintain highly reliable infrastructure for email delivery systems, APIs, tracking systems, and automation platforms
- Improve observability across distributed systems using logging, metrics, tracing, and alerting
- Optimize infrastructure and application performance at scale
- Automate infrastructure provisioning, deployments, recovery, and operations workflows
- Work on mail delivery infrastructure, queues, DNS, networking, and throughput optimization
- Collaborate closely with backend engineers on architecture, scalability, and incident response
- Reduce operational overhead through tooling and automation
Responsibilities
- Infrastructure & Automation
- Manage infrastructure using Infrastructure as Code
- Automate provisioning and deployments using:
- Terraform
- Ansible
- Improve CI/CD pipelines and deployment reliability
- Build reusable infrastructure modules and internal tooling
- Manage cloud infrastructure, networking, and security hardening
Observability & Reliability
- Set up and maintain:
- Centralized logging
- Metrics pipelines
- Distributed tracing
- Alerting systems
- Build actionable dashboards and SLO/SLA monitoring
- Perform root cause analysis during production incidents
- Improve MTTR and system resilience
Performance Engineering

Strong understanding of:
- Linux internals
- TCP/IP
- DNS
- SMTP
- Reverse proxies/load balancers

What We’re Looking For
- Strong problem-solving ability and debugging mindset
- Someone who enjoys understanding how systems work internally
- Bias toward automation and operational simplicity
- Ability to work independently and own infrastructure reliability
- Comfortable in fast-moving startup environments
- Performance and scalability oriented thinking
Bonus Points
- Experience with high-scale email infrastructure
- Experience handling millions of events/messages per day
- Knowledge of SMTP deliverability and mail systems
- Experience with distributed systems and event pipelines
- Familiarity with security hardening and incident response
- Experience building internal DevOps platforms/tooling
- Proof of work: open source projects, github public repos, deeply technical articles etc.
Why Join
- Work on real-scale infrastructure problems
- High ownership and autonomy
- Opportunity to shape core infrastructure architecture
- Performance-first engineering culture
- Small, highly technical team with deep systems focus
