Is there a good muhūrta for signing a contract or joining a new job?

yes — pick a good tithi, weekday and nakṣatra and avoid Rāhu kāla if you can; but never delay a sound decision just for timing.

For agreements, tradition prefers “fixed” (sthira) nakṣatras such as Rohiṇī and the three Uttarās for lasting arrangements, and gentle ones like Hasta, Citrā, Anurādha and Revatī for cooperation. Wednesday (Mercury, contracts and communication) and Thursday (Jupiter, wisdom) are common choices, along with tithis like dvitīyā, tṛtīyā, pañcamī, saptamī, daśamī and ekādaśī. Riktā tithis (caturthī, navamī, caturdaśī) and Amāvasyā are usually avoided.

For a new job, you often can't choose the joining date. In that case simply avoid Rāhu kāla on the day if possible, pray before leaving home, and begin with sincerity.

Most important: muhūrta supports a good decision; it cannot rescue a bad one. Read the contract carefully and take legal or financial advice where needed — that is the first “auspicious” step.
