Question 1

Is Go or Java easier to hire for in 2026?

Accepted Answer

Both Go and Java have active talent pools on Haystack. We see first shortlists for Go and Java land within 24 hours of kick-off, with the median Go hire closing in 14-21 days alongside comparable Java roles.

Question 2

What does a Go developer cost vs a Java developer?

Accepted Answer

Mid-level Go engineers anchor around £70k–£95k UK base, with seniors reaching £100k–£145k. Java engineers sit around £70k–£90k mid and £95k–£135k senior. German bands run 5-20% higher in EUR and US bands 40-50% higher in USD.

Question 3

Which ecosystem libraries should I screen for - Go or Java?

Accepted Answer

For Go we look for working experience with gRPC, Kubernetes, Docker. For Java the equivalents are Spring Boot, Kotlin, Kafka. Both ecosystems get surfaced on every Haystack profile so you can filter on exact tooling.

Question 4

Can the same engineer cover both Go and Java?

Accepted Answer

Often yes - particularly when both stacks live in the same category (Backend vs Languages). On Haystack we let you require both as primary or secondary skills; senior generalists typically carry one as their main stack and one as supporting.

Question 5

Should I bet on Go or Java for a greenfield project?

Accepted Answer

Pick on hiring depth, your team's current strengths and the ecosystem fit. Go suits grpc and http apis handling 10k+ rps per instance; Java suits spring boot microservices on kubernetes. We can shortlist both in parallel so you can interview against the same brief.

Question 6

Do you cover senior and staff Go and Java engineers?

Accepted Answer

Yes - the full ladder from junior through staff/principal in both Go and Java. The kick-off call captures the level and shipped-work bar you need, and shortlists are filtered accordingly.
