Team expansion
Team Expansion embeds Hello World senior engineers, designers, or strategists into your existing team for weeks or months. Operating in your repo, your standups, and your communication tools. You keep the project ownership; we add capacity, expertise, or specific skills your hiring pipeline can't fill on the timeline you need.
How we approach it
Embedded, not contracted
We work in your tools, attend your standups, follow your engineering norms. The work product is yours from day one.
Senior by default
You get experienced engineers and designers. No bench-warming, no junior labor billed at senior rates.
Skill match, not headcount
We pair specific people to specific gaps. Accessibility audit, performance, headless migrations, ACF/Gutenberg complex builds.
Ramp + handoff are part of the scope
We onboard responsibly, document what we learned, and hand off cleanly when the engagement ends.
What's included
- Dedicated senior engineer, designer, or strategist for an agreed time period
- Embedded in your sprint cadence, repo, and communication tools
- Code review, mentoring, and pairing with your existing team
- Optional access to broader Hello World specialists (accessibility, performance, AI) for specific spikes
- Documented handoff including what was built, what was learned, what comes next
- Weekly check-ins with the engagement lead for scope + capacity adjustments
Who it's for
In-house teams with a delivery gap
You have engineering staff but need extra senior capacity for a quarter or two without permanent hire.
Teams with a specialized need
Accessibility audit, headless migration, AI integration, performance work. Skills that aren't worth a full-time role.
Organizations between hires
Lead engineer left, search is 4â6 months out, the work can't wait.
What it costs
Engagements start at one senior person at 50% capacity per month and scale up. Pricing depends on seniority, skills, and engagement length. Typical ranges are $12Kâ$30K per person per month.
Common questions
Do we get the same person the whole engagement?
Yes. We pair you with a specific person and don't swap them out mid-engagement unless you ask us to. Continuity is part of why team expansion works.
How is this different from a contract developer?
Embedded engagement, not transactional. We participate in your team's rituals, follow your standards, and own outcomes with you. The work also comes with the wider Hello World team behind it. Specialists you can pull in for spikes.
What's the minimum engagement length?
Two months. Shorter than that and the ramp cost outweighs the value.
