Senior judgment
Knowing which corners can be cut and which never should be, and being able to explain the difference.
Senior engineer bar
What senior means here.
The engineer standard defines how TwinTeams evaluates seniority: communication, code quality, AI workflow judgment, and delivery ownership. It's the bar candidates are assessed against and engineers are supported to.
Standard definition
Seniority is a working pattern.
Years of experience tell you what someone has seen. The standard measures what they reliably do: three patterns that show up within the first weeks on any new team.
Written clarity
Decisions, progress, and risks written so a stakeholder in another timezone acts on them without a meeting.
Delivery ownership
Treating shipping as the job: unblocking, escalating early, and finishing what was started.
Engineer dimensions
The dimensions we assess.
Each one is observable in normal delivery.
Async communication
Updates that answer the next question before it's asked. Written first, meetings only when they earn their cost.
Code review practice
Reviews that improve the codebase and the author: specific, kind, and fast enough not to block.
AI-assisted workflow
Using AI tooling where it compounds output, and personal judgment where correctness matters.
Access discipline
Careful, boring, consistent handling of credentials, environments, and customer data.
Escalation judgment
Raising risks while they're cheap. The engineer who says 'this worries me' on Tuesday saves the Friday.
Our Jevons paradox position explains why AI-assisted delivery raises the value of senior judgement rather than removing it.
Working habits
What the standard looks like day to day.
- 01
Read
Understand the repo, product context, constraints, and how the team already works.
- 02
Write
Make thinking visible through concise updates, notes, and implementation records.
- 03
Review
Use code review as a quality loop, not a gatekeeping ceremony.
- 04
Escalate
Surface risk early and ask for decisions while options still exist.
- 05
Improve
Turn delivery feedback into better delivery habits over time.
Team confidence
Put the standard to work on your team.
Every TwinTeams engineer is assessed against this standard before they join your team. Start with the roles you need and we'll propose the engineers.
