Observability Engineer
Metrics, traces, logs at scale. Prometheus, OTel, the cost spreadsheet.
Underrated specialism, almost always understaffed, with a career arc that compounds quietly. Pick it if you actually care about what production is telling you.
- Domain
- Platform / DevOps
- Entry
- £45–68k
- Senior
- £115–150k
- You enjoy structured data, sampling and cardinality problems
- You like working closely with engineering and SRE on incidents
- You're happy quantifying things others guess at
- You can keep cost under control while improving signal
- You see observability as 'just dashboards'
- You don't enjoy long-running platform work
- You'd struggle being the team that explains its value every budget cycle
What "doing well" looks like in the seat
- Incidents get resolved faster because of telemetry you shipped
- Other teams ship with instrumentation by default, not as an afterthought
- You can defend your sampling and retention choices on paper
- Your vendor spend goes down at least once a year without losing fidelity
The role lives or dies on leadership maturity. Without an engineering culture that takes signal seriously, you'll spend two years building dashboards nobody opens. With one, you'll be one of the most influential infrastructure engineers in the org. Interview hard for whether observability is owned, funded, and used in decision-making. If it's a side-of-desk job for the platform team, the seat will frustrate you.
