Ensuring the reliability and availability of software systems is crucial for businesses that rely on technology to deliver their services. From e-commerce platforms to cloud-based infrastructures, minimizing downtime and responding quickly to incidents is essential. This is where on-call frameworks come in.
On-call frameworks are designed to distribute the responsibility of incident response across engineering teams, ensuring that production issues are promptly detected and addressed. These frameworks typically assign engineers to on-call rotations, allowing them to monitor and handle incidents outside of regular business hours. By assigning these duties on a rotating basis, organizations ensure that there is always someone available to maintain system uptime and performance.
The on-call software engineer is central to this process. These engineers serve as the first line of defense, responding to alerts, diagnosing issues, and coordinating incident resolution. Their role extends beyond just troubleshooting; they help maintain overall system stability and ensure that potential problems are resolved before they can impact users. Whether handling urgent outages or addressing smaller issues, on-call engineers play a critical role in maintaining the reliability of modern software systems.
This blog will explore the life of an on-call software engineer, their responsibilities, the challenges they face, and how tools and automation are making their workflows more efficient.
On-call engineers play a crucial role in ensuring system reliability and incident resolution. Their day-to-day tasks can vary widely depending on the nature of the incidents, but several common aspects define their responsibilities during an on-call shift.

Below is a breakdown of these key points:
By breaking down the on-call engineer's life into these key responsibilities, it's clear that their role goes beyond just reacting to problems. It involves a systematic approach to incident management, problem-solving, and post-incident learning, ensuring that systems remain stable and reliable even in the face of unexpected issues.
On-call engineers play a critical role in maintaining system reliability, but the job comes with its own set of challenges. These can affect not only their performance but also their well-being.
Below are some of the common challenges faced by on-call engineers:
One of the biggest challenges is dealing with a high volume of alerts. Engineers may receive frequent notifications, many of which can be false positives or non-critical issues.
This constant barrage of notifications can lead to alert fatigue, where engineers become desensitized to alerts and may overlook critical issues. It also diminishes their productivity and focus.
Being on-call often means engineers can be woken up at odd hours to address incidents. These interruptions, especially at night or during weekends, can severely affect their personal time and rest.
Repeated sleep disruptions lead to exhaustion, reduced mental clarity, and decreased efficiency in handling incidents. Over time, this can also take a toll on their overall health and work-life balance.
On-call responsibilities often overlap with the engineer’s regular project work. Since on-call tasks take precedence, managing both can be difficult.
Engineers might struggle to balance their on-call duties with their sprint goals or ongoing projects, leading to delays or incomplete tasks. This also adds extra stress, especially when tight project deadlines loom.
Handling high-pressure situations, especially during critical system outages or urgent incidents, can cause significant mental and physical stress.
The intense pressure to resolve issues quickly, combined with the urgency of some incidents, can lead to burnout. Over time, this constant stress may reduce job satisfaction and the ability to perform effectively.
These challenges highlight the demanding nature of the on-call engineer’s role. Organizations need to be mindful of these factors, implementing solutions like automation, better alert management, and fair on-call rotation schedules to minimize the strain on their engineers.
To handle the unpredictable and often stressful nature of on-call duties, teams can adopt several best practices to enhance their effectiveness and reduce the strain on engineers.
Here are some key strategies for ensuring smooth and successful on-call operations:
Clear and timely communication is crucial when resolving incidents, especially when multiple team members or stakeholders are involved.
Use a dedicated communication channel, such as Slack or Microsoft Teams, for incident discussions to keep everyone updated. Ensure that all relevant stakeholders are promptly informed about the status of the issue and any necessary next steps.
Effective communication reduces confusion and ensures that everyone involved is on the same page, leading to faster resolutions and smoother handoffs during escalations.
Keeping accurate records of incidents, resolutions, and Root Cause Analyses (RCA) is essential for future reference and process improvement.
Maintain detailed incident logs and ensure that every alert and response is well-documented in a centralized ticketing system. This makes it easier to track patterns, review incidents, and create RCA documents later.
Thorough documentation improves team learning, prevents future incidents, and provides valuable insights for postmortems and process optimization.
On-call engineers often face high-pressure situations, particularly when resolving critical incidents that impact business operations.
Engineers should adopt mental strategies such as staying calm under pressure, breaking down complex problems into smaller tasks, and following Standard Operating Procedures (SOPs) to avoid panic.
Mental preparation and resilience help engineers remain focused during stressful incidents, enabling them to manage critical situations more effectively and avoid burnout.
On-call teams are more effective when they collaborate and share knowledge about recurring issues, systems behavior, and best practices for incident management.
Encourage regular knowledge-sharing sessions where team members discuss incidents, resolutions, and potential improvements to workflows. Utilize runbooks to ensure that all engineers have access to standardized procedures.
Collaboration fosters a culture of continuous improvement and makes it easier for engineers to troubleshoot incidents efficiently by leveraging shared expertise and documented processes.
By following these best practices, on-call teams can improve their ability to respond to incidents, reduce the strain on individual engineers, and create a more efficient, resilient on-call system.
As the role of on-call engineers has evolved, so have the tools and methodologies that support them. Modern improvements like runbooks and automation tools such as Doctor Droid Playbooks are transforming the way on-call engineers handle incidents. These advancements help engineers resolve issues more efficiently and reduce the need for constant manual intervention.
Here’s how these tools are making an impact:
Runbooks are pre-defined procedures created by product owners or senior engineers that guide on-call teams in resolving specific issues. These step-by-step guides outline how to troubleshoot common problems or respond to specific symptoms in the system.
By providing a clear set of instructions, runbooks empower on-call engineers to resolve issues independently without needing to escalate them to other teams. This reduces the time to resolution and ensures that even less experienced engineers can handle incidents effectively.
Runbooks significantly reduce the cognitive load on engineers during stressful situations by offering structured solutions. They also improve consistency across the team, as all engineers follow the same standard operating procedures.
Doctor Droid Playbooks automate first-level diagnosis and incident management. By pre-configuring metrics and log queries tailored to different types of alerts, these playbooks allow engineers to quickly gather relevant data for troubleshooting.
Instead of manually searching through logs or running custom queries, Doctor Droid Playbooks automatically fetch the required data based on the alert type. This enables engineers to quickly assess the situation and decide on the best course of action without delay.
Automation through tools like Doctor Droid Playbooks speeds up the incident response process by eliminating manual steps. Engineers can address issues faster, minimize downtime, and focus on solving the problem rather than spending time gathering information.
To ensure that on-call practices are efficient and impactful, it's important to measure and evaluate performance through key metrics. These metrics help teams understand how effectively incidents are being handled, identify areas for improvement, and ensure continuous optimization of the on-call process. Below are some crucial metrics to track when assessing on-call effectiveness:
This metric measures the average time it takes for an on-call engineer to acknowledge an alert after it’s raised. A low MTTA indicates that alerts are being responded to quickly, minimizing the risk of incidents escalating.
Faster acknowledgment ensures that issues are addressed before they worsen, improving overall system reliability.
MTTR tracks the average time it takes to fully resolve an incident, from the moment the alert is acknowledged to its final resolution. Lower MTTR indicates efficient problem-solving and swift recovery.
Reducing MTTR minimizes downtime and ensures that system disruptions have a minimal impact on users or customers.
This metric refers to the total number of incidents or alerts that are triggered within a specific period. Monitoring incident volume helps teams identify trends, such as recurring issues or specific times when incidents tend to occur more frequently.
High incident volume may indicate underlying system health issues or poor alert configurations, both of which need addressing.
Escalation rates measure how often incidents are passed on from the first responder to a secondary or higher-level team member. High escalation rates may indicate that on-call engineers are facing issues beyond their scope.
If escalation rates are consistently high, it may be a sign that additional training, better SOPs, or more automation is needed to help first responders manage incidents more effectively.
Regularly tracking these metrics provides valuable insights into how well the on-call process is functioning. Teams can use this data to pinpoint bottlenecks, improve their workflows, and refine their response strategies.
The life of an on-call software engineer is both challenging and rewarding, as they play a critical role in maintaining the reliability and availability of modern software systems. From handling high-pressure incidents and balancing project work to documenting incidents and ensuring post-incident improvements, on-call engineers are essential for keeping systems running smoothly.
By embracing best practices such as clear communication, effective documentation and leveraging modern tools like runbooks and automation platforms such as Doctor Droid Playbooks, on-call engineers can significantly improve their workflows. These tools help reduce alert fatigue, automate routine tasks, and streamline incident resolution, making on-call duties more manageable and efficient.
As technology continues to evolve, the role of the on-call engineer will likely become even more proactive, supported by AI-driven systems and self-healing platforms. The future of on-call engineering looks promising, with a focus on reducing manual intervention and improving the overall on-call experience, ensuring that systems remain resilient, even in the face of unexpected challenges.
