When to choose Opus
Choose us when you need a senior person who reports to your manager and stays focused on your team. We employ the hire and handle contracts, payroll, benefits and labor compliance. You choose the person and set their priorities. That model also works for a finance, RevOps or marketing role.
BairesDev is worth comparing when several engineers must work on one roadmap or you want a provider to run a software project. Its dedicated-teams page spans 100+ technologies. Staff augmentation is also an option for a single engineer, so team size alone does not settle the choice.
Compare the employment model
Ask who owns code review, delivery deadlines and the employment agreement. A dedicated hire under your manager and an outsourced project need different terms. Opus quotes one flat monthly rate per hire on the first call. BairesDev doesn't publish a rate card.
Role brief: senior backend engineer (fictional example)
A Series B software team needs one senior backend engineer to own service reliability. Your engineering manager reviews the work and approves production access. Ask candidates to walk through a past incident, explain the fix and review a small service diagram. Agree on a first-month reliability review before asking for a full rebuild.
If the work instead needs several engineers and a delivery lead, ask BairesDev for a dedicated-team or outsourced-project scope.
Ask BairesDev
- Does this proposal cover staff augmentation, a dedicated team or outsourced delivery?
- Who directs the engineers and owns code review and deadlines?
- Which engineers are assigned to us, and what are their countries and agreed hours?
- Does the timeline mean first profiles, a complete team or the first day worked?
- What replacement remedy, notice period and handover duties are in the contract?
