Sharing a data point since i never see Datadog comp in the wild.
Senior SWE (L4 equivalent), New York office, offer accepted March 2026: Base: $195k RSU: $280k over 4 years (1-year cliff then quarterly vest) Bonus target: 15% of base, not guaranteed Sign-on: $30k (one-time, clawback if leave before 12 months)
Total year 1 rough: ~$295k all-in depending on bonus. Year 2+ closer to $260-$270k after sign-on drops off.
They don't talk about RSU refreshes upfront but apparently performance refresh reviews happen annually. Negotiated base up $10k from initial and got a small sign-on bump. They didn't move on RSU grant at all.
Healthcare was solid. Unlimited PTO which at my last two companies has meant "use it or feel guilty." Equity vesting cliff is worth noting if you're comparing to companies with monthly vesting.
