DevOps Engineer for SaaS Startup: What to Budget and What to Expect in the First 90 Days

Month 1: Foundation (Days 1 to 30)  -  $3,200

Focus: Infrastructure audit, cloud migration or setup, CI/CD pipeline, monitoring.

Week 1: Infrastructure audit and environment review. The DevOps engineer maps the current state: what is running where, what the deployment process looks like, where the single points of failure are, and what the biggest immediate risks are. Audit findings delivered to the CTO by end of week 1.

Week 2: Cloud setup or migration. If the product runs on a single VPS or shared hosting, the cloud migration begins. VPC, managed database (RDS), load balancer, and initial EC2 Auto Scaling Group. If the product is already on cloud, the DevOps engineer remediates the audit findings (missing Multi-AZ, misconfigured security groups, no monitoring).

Week 3: CI/CD pipeline. Automated build, test, and deployment pipeline. Code pushed to main branch deploys to staging automatically. Production deployments require a manual approval gate.

Week 4: Monitoring and alerting. CloudWatch dashboards for CPU, memory, error rate, and request latency. Alerts configured to Slack. The team discovers infrastructure problems from signals, not from user reports.

Month 1 measurable outcome: the product deploys automatically, the team can see infrastructure health at a glance, and the biggest reliability risks from the audit have been resolved.

Month 2: Reliability and Scale (Days 31 to 60)  -  $3,200

Focus: Zero-downtime deployments, auto-scaling, cost optimisation, SonarQube or security scanning.

Week 5 to 6: Zero-downtime deployment strategy. Blue-Green or Rolling deployment configured so releases do not take the product offline. Every deployment from this point is zero-downtime.

Week 7: Auto-scaling configuration. EC2 Auto Scaling Group with Target Tracking policy. Instances scale up automatically during traffic spikes and scale down during quiet periods. Idle compute cost reduces by 20 to 35%.

Week 8: Cloud cost review. The DevOps engineer audits the cloud bill against the 8 waste categories: orphaned resources, dev/staging schedules, S3 lifecycle policies, CloudWatch log retention. Quick wins implemented immediately.

Month 2 measurable outcome: zero downtime on every deployment, auto-scaling handling traffic variability, cloud bill measurably lower than Month 1.

Month 3: Optimisation and Handoff (Days 61 to 90)  -  $3,200

Focus: Infrastructure as Code (Terraform), security hardening, documentation, Reserved Instances.

Week 9 to 10: Terraform migration. Existing infrastructure is imported into Terraform code. All future infrastructure changes go through a Git PR process rather than manual console operations. The infrastructure is now version-controlled and reproducible.

Week 11: Security hardening. IAM role review (least-privilege audit), security group tightening, Secrets Manager configuration for database credentials and API keys. Any SonarQube integration not completed in Month 2 is finished here.

Week 12: Reserved Instances and documentation. Based on the right-sized baseline from Month 2, a 1-year Reserved Instance or Savings Plan is purchased. Onboarding documentation and infrastructure runbook delivered. Reserved Instances produce 30 to 40% compute cost reduction going forward.

Month 3 measurable outcome: all infrastructure in Terraform code, security baseline met, Reserved Instances purchased, runbook delivered. The product has a documented, reproducible infrastructure that any future DevOps engineer can pick up.

Cost or saving category

90-day figure

Ongoing (month 4+)

DevOps engagement cost

$9,600 (3 x $3,200/month)

$3,200/month if retained

Cloud cost saving (auto-scaling + idle resources)

$900 to $2,000 saved in month 2-3

$900 to $2,000/month ongoing

Reserved Instance saving (30 to 40% compute reduction)

Purchased in month 3

$500 to $2,000/month ongoing

Incident resolution time saving

Hours saved per month from Terraform + monitoring

2 to 5 hours/month saved ongoing

Deployment downtime eliminated

Zero downtime from month 2 onwards

Zero downtime every deployment

Net 90-day cost (after cloud savings)

$9,600 minus $1,800 to $4,000 in savings = $5,600 to $7,800 net

Monthly saving exceeds engagement cost by month 4

Continue the monthly retainer

The DevOps engineer transitions from build mode to operate mode. Ongoing work: monitoring and incident response, pipeline maintenance, cost optimisation reviews, infrastructure changes as the product grows, Kubernetes migration if the product scales to require it. Cost: $3,200/month. Right for: teams where ongoing infrastructure ownership is needed and the engineering team does not have DevOps depth in-house.

Reduce to a part-time engagement

After the 90-day foundation, many SaaS products need 1 to 2 days of DevOps work per month rather than full-time. Acquaint Softtech provides part-time engagements at $22/hour for teams at the maintenance and optimisation stage. Right for: stable products with low change rate where the cost of a full-time retainer is not justified.

Hand off to an in-house DevOps engineer

The 90-day engagement produces documentation, Terraform code, and a runbook that any new DevOps engineer can inherit. Some founders use Acquaint Softtech to build the infrastructure and then hire an in-house engineer to own it long-term. The handoff includes a structured knowledge transfer session. Right for: teams scaling to a stage where in-house DevOps ownership is a business requirement.
