About CrossX
Where experienced engineers and ambitious teams cross paths.
CrossX exists for a simple reason: companies with real deadlines need senior engineering talent they can trust, without waiting months to hire it.
The name is the model: our engineers cross into your team, and the work crosses the finish line.
We build software for clients and we embed senior engineers in client teams. Both rest on the same idea — experienced people, close to the work, accountable for what ships. No layers of account managers translating between you and the engineers. No juniors learning on your production systems.
Connecticut roots
Based in Connecticut. Built for US teams.
CrossX is headquartered in Connecticut, and we organize our work around the realities of US companies: overlapping working hours, clear written communication, and engineers who are comfortable in front of your stakeholders. Wherever your team sits, you get a partner that keeps your hours and speaks your language — technical and commercial.
- Working hours that overlap with US time zones
- Direct access to the engineers doing the work
- Contracts and communication that fit US businesses
The senior-only principle
Why we only staff senior engineers.
Seniority isn't about years on a résumé. It's judgment: knowing which problems matter, what to leave out, when to push back, and how to leave a codebase better than you found it.
Faster to useful
Senior engineers ramp up on unfamiliar systems quickly and need less hand-holding from your leads.
Lower cost of ownership
Fewer shortcuts that turn into rewrites. Code that's tested, readable and ready to maintain.
Direct accountability
The person who estimated the work is the person who delivers it — and answers for it.
Capability that stays
Senior engineers mentor, review and document, so your team grows while the work gets done.
What we value
The standards we hold ourselves to.
Candor
We tell clients what they need to hear — about scope, risk, fit and timelines — even when it's inconvenient.
Ownership
We act like the outcome is ours, because our reputation depends on it.
Craft
Clean, tested, observable software isn't gold-plating. It's what lets you move fast next quarter.
Respect for your team
We join your culture rather than impose ours, and we make the people around us better.
