On March 15, 2021, I resigned from a Staff Engineer role at AWS earning $352,000 base plus $180,000 in RSUs to work full-time on open-source observability tools. My first year’s total income: $132,000. That’s a 68% pay cut, not the 60% I’d estimated. I’ve never regretted it.

Why I Left a $532k/Year Job
I spent 7 years at AWS, rising from SDE II to Staff Engineer on the CloudWatch team. By 2020, I was earning $352k base salary, $180k in RSUs, and $40k in bonuses, for a total of $572k annual compensation. But I was miserable. I worked 70-hour weeks, 12 hours of which were meetings: sprint planning, retros, OKR reviews, cross-team syncs, vendor calls. I spent 10% of my time writing code, 90% on documentation, code reviews, and office politics. I realized I’d become a manager who writes code occasionally, not an engineer.
I’d been contributing to OpenTelemetry on weekends for 2 years, and my side project—a CloudWatch exporter for OpenTelemetry—had 12k stars on GitHub. In January 2021, the OpenTelemetry governance committee reached out: they had a grant from the Linux Foundation to fund 3 full-time maintainers for the Go SDK, and they offered me a role. I calculated my income: $120k from the Linux Foundation grant, $12k from existing GitHub Sponsors, total $132k. That’s a 76% pay cut from my total AWS compensation, or 68% from my base salary. I debated for 2 months, then resigned on March 15, 2021.
The First 6 Months: Income Volatility and Imposter Syndrome
The first 6 months were the hardest. My sponsorship income was $8k in April, $9k in May, then $14k in June when a blog post I wrote about the CloudWatch exporter went viral. I burned through $42k of my savings in those 6 months, as my income was below my $10k/month expenses (mortgage, health insurance, kid’s daycare). I also struggled with imposter syndrome: I was used to having my work reviewed by senior engineers, and suddenly I was the senior engineer. I worried that my contributions weren’t good enough, that I’d let the community down.
But then I noticed something: without 12 hours of meetings a week, I was writing code 40 hours a week, compared to 10 hours a week at AWS. By month 6, I’d contributed 3x more code to OpenTelemetry than I had in the entire previous year at AWS. My imposter syndrome faded when the batcher refactor I led was merged into OpenTelemetry Go 1.21.0, used by 1000+ companies. The income volatility didn’t go away—my sponsorship income ranged from $8k to $18k per month for the first 2 years—but I’d never been happier.

Case Study: OpenTelemetry Go Batcher Refactor
- Team size: 3 full-time open-source maintainers, 2 regular community contributors
- Stack & Versions: OpenTelemetry Go 1.20.0, Prometheus 2.45.0, Grafana 10.2.3, Go 1.21.4
- Problem: p99 metric export latency for a top-10 e-commerce company using the OpenTelemetry Go SDK was 2.1s, leading to 12% of alert evaluations failing due to stale metrics, costing an estimated $26k/month in on-call overtime and false positive remediation
- Solution & Implementation: We refactored the gRPC metric batcher to use sync.Pool for zero-copy buffer allocation, added dynamic batch sizing that adjusts based on real-time export latency feedback, and implemented retry logic with exponential backoff for failed exports, all contributed over 4 months of full-time work
- Outcome: p99 export latency dropped to 89ms, export failure rate fell to 0.2%, eliminating $22k/month in avoidable costs for the e-commerce company, with the changes merged into OpenTelemetry Go 1.21.0
Developer Tips
Tip 1: Negotiate Sponsorship Before You Quit
One of the biggest mistakes I made was quitting before I had a stable sponsorship runway. I assumed that my 12k stars on my side project would translate to immediate $10k/month sponsorships, but it took 6 months to hit that mark. Before you resign, set up GitHub Sponsors, OpenCollective, and Patreon accounts, and reach out to the 10 largest corporate users of your open-source project. For example, if you maintain a popular Go library, reach out to the DevOps leads at companies like Uber, Netflix, and Datadog—they’re often willing to sponsor $500-$2k/month to ensure the project stays maintained. Use the GitHub Sponsors API to check which of your contributors are sponsored, and send them a personalized email asking for support. I recommend having at least 6 months of living expenses in savings plus $3k/month in committed sponsorships before you quit. The volatility of open-source income is real: my sponsorship income ranged from $8k to $18k per month in the first year, which made budgeting extremely difficult. Tools like gh-sponsors CLI can help you manage sponsorships directly from the terminal. Here’s a quick snippet to list your current sponsors:
gh sponsors list --user yourusername --json login,monthlyPledge
This will output a JSON list of all your sponsors and their monthly pledges, making it easy to track your income. I also recommend setting up a tiered sponsorship model: $5/month gets a thank you note, $50/month gets a mention in release notes, $500/month gets a 1-hour consulting call. This tiered model increased my sponsorship income by 40% in the first 3 months of implementing it.
Tip 2: Build a Maintenance Runway for Your Projects
When you’re working full-time on open source, you’ll quickly realize that maintenance work (updating dependencies, triaging issues, responding to PRs) takes up 60% of your time, leaving only 40% for new features. To avoid burnout, automate as much maintenance as possible. Set up Dependabot, Renovate, or Mergify to automatically update dependencies, run tests, and merge minor patches. Configure issue templates and PR templates to reduce back-and-forth with contributors: for example, require that all bug reports include a minimal reproducible example, and all PRs include unit tests and documentation updates. I use Renovate for all my projects, which automatically creates PRs for dependency updates, runs CI, and merges them if all tests pass. Here’s a sample Renovate configuration for a Go project:
{
\"extends\": [\"config:base\", \"schedule:nonOfficeHours\"],
\"packageRules\": [
{
\"matchPackagePatterns\": [\"*\"],
\"matchUpdateTypes\": [\"minor\", \"patch\"],
\"automerge\": true
}
],
\"go\": {
\"enabled\": true
}
}
This configuration automatically merges minor and patch dependency updates for Go projects outside of office hours, reducing the number of notifications you get during your deep work time. I also recommend setting up a community Slack or Discord for your project: it reduces the number of GitHub issues for simple questions, and builds a community of contributors who can help with maintenance. In my experience, a 500-member community can handle 70% of triage and support work, freeing you up to focus on high-impact features. Just make sure to set clear community guidelines to prevent harassment and off-topic discussions.
Tip 3: Document Opportunity Cost Publicly
One of the biggest challenges of open-source work is proving your impact to potential sponsors. Corporate engineers have OKRs, performance reviews, and promotion cycles to quantify their work—you have none. To solve this, build a public dashboard that tracks your project’s impact: number of monthly active users, number of companies using your project, latency improvements, cost savings for users, etc. Use Grafana and Prometheus to track these metrics, and publish the dashboard publicly so sponsors can see exactly what their money is supporting. For example, my OpenTelemetry Go dashboard shows that the batcher refactor I worked on saved 100+ companies an estimated $2.2M/year in export costs. Here’s a PromQL query to track monthly active users of your project via download counts:
sum(rate(github_release_download_count{repo=\"yourusername/yourrepo\"}[30d])) * 30
This query calculates the estimated monthly download count for your GitHub releases, which is a good proxy for monthly active users. I also recommend writing a quarterly impact report: summarize the features you shipped, the number of issues closed, the number of contributors added, and the total cost savings for users. Send this report to all your sponsors, and post it publicly on your project’s blog. My Q3 2023 impact report led to 3 new $1k/month sponsorships, because sponsors could see exactly how their money was being used. Remember: open-source work is invisible if you don’t document it—no one will sponsor work they don’t know is happening.
Join the Discussion
Open source sustainability is one of the most pressing issues in infrastructure engineering today. I’ve shared my raw numbers, code, and lessons below—now I want to hear from you.
Discussion Questions
- Will corporate open-source sponsorship programs like GitHub Sponsors for Enterprise replace traditional maintenance grants by 2028?
- What’s the biggest trade-off you’d face if you left a six-figure corporate role for full-time open-source work?
- How does the contribution velocity of full-time maintainers compare to part-time volunteers using tools like GitPrime?
Frequently Asked Questions
Did you have to dip into savings to make the switch?
Yes, I burned through $42k of my savings in the first 6 months of full-time open-source work. My sponsorship income was below my monthly expenses of $10k, as I was still building my sponsor base. I hit breakeven in month 18, when my sponsorship income reached $10k/month. I recommend having at least 12 months of living expenses in savings before making the switch, to avoid financial stress while you build your income stream.
How do you handle health insurance without a corporate job?
I used COBRA for 18 months after leaving AWS, which cost $480/month for a family plan, compared to $120/month at AWS. After COBRA expired, I switched to a health insurance plan through the Freelancers Union, which costs $520/month but has better coverage. I also qualified for a $300/month subsidy in 2023 due to my reduced income, which brought the cost down to $220/month. Health insurance is one of the biggest hidden costs of leaving a corporate job, so factor that into your budget.
Do you ever miss the corporate perks like free meals or travel?
I missed the $2k/month meal stipend and free travel at first, but I’ve gained 15 hours/week of deep work time, which led to 3x more code contributions than my peak corporate output. I also get to travel to open-source conferences like KubeCon and Observability Day, which are paid for by the Linux Foundation grant. The perks are different, but the autonomy and flexibility of open-source work far outweigh the loss of corporate perks.
Conclusion & Call to Action
If you’re a senior engineer feeling burnt out by corporate politics, endless meetings, and 10% coding time: consider open source. It’s not for everyone—the income cut is real, the volatility is stressful, and you’ll miss corporate perks. But if you value autonomy, deep work, and building software that helps thousands of engineers, it’s worth it. My only regret is not doing it sooner. If you’re thinking about making the switch, start contributing to open source on weekends, build a sponsorship runway, and document your impact. The open-source community needs more full-time maintainers, and the work is more rewarding than any corporate job I’ve ever had.
