Commercial counsel is the biggest single title in this group, and the corpus also contains legal engineer as a distinct role — someone who builds the systems that make legal work scale rather than performing the legal work itself.

• Contract volume is the constraint. A growing SaaS company signs more agreements than counsel can review individually, so the job becomes templates, playbooks, fallback positions and self-service.
• The recurring negotiations are few. Liability caps, indemnities, data processing, security commitments, termination. Knowing the standard positions and where your company will actually move is most of commercial counsel.
• AI contracting is newly load-bearing — training-data rights, output ownership, indemnity for model outputs, and what a vendor may do with your inputs. This is one of the fastest-moving areas in the corpus.
• Privacy is adjacent and often the same person at smaller companies — DPAs, sub-processors, transfer mechanisms, retention.
