Hi everyone!

Background:

• Graduating Spring 2026, ~1 year at a non-profit cancer research (interned summer 2025, returned full-time April 2026 as Data Engineer)
• Comp is <$110k, fully remote, living at home in the Bay Area, I can just play the long game -> but i don't want to I want to get out there and chase
• Manager has indicated I'm tracking for promotion by end of 2027
• Genuinely love my team. Good people, supportive manager, stable + well-funded org, meaningful mission. No complaints about the actual job, this post is purely me thinking ahead about my career beyond this company.
• I am being transitioned to own a data product within company by July since I initiated it as an intern and am very comfortable within it

My concern:

Our stack is Python, SQL, AWS (Lambda, Glue, Aurora) GCP, Terraform, potentially iceberg. Solid stuff, but we don't use Spark, Kafka, Snowflake, Databricks, Iceberg, dbt, Airflow, or really any of the "modern" DE tools that dominate job postings. I'm worried that even with strong scope and a promotion, I'm building experience on a stack that doesn't transfer cleanly to where the market is going.

My rough plan:

• Throw applications out for Fall 2026 new grad cycles, don't expect much but applications are free and i have just picked up prepping again
• Realistic target is Fall 2027 / mid-2028 since I've fell off with leetcode and system design prep, post-promotion, for newgrad/entry level roles at companies with modern stacks

What I am asking:

When does being comfortable/slow and steady stop paying off vs. "you're falling behind on tools and need to leave for a more modern environment"?

Specifically:

1. How much does a non-modern stack actually hurt at 2 YOE if I have strong ownership/scope to talk about? Or do hiring managers screen out for "doesn't have Spark/other tools experience" regardless?
2. For people who've been in a similar spot (stable role, outdated stack, comfortable comp), when did you know it was time to leave? Did you regret staying or regret leaving?

Thank you!
