Should husband and wife do pūjā together?

yes — in Hindu tradition the couple are partners in dharma, and many rites are meant to be done together.

At the wedding the couple take the seven steps (saptapadī) together and become sahadharmiṇī and sahadharmī — partners in dharma. For major rites such as a Satyanārāyaṇa pūjā, a gṛha-praveśa, a havan or a saṁskāra for their child, the husband and wife traditionally sit together and take the saṅkalpa jointly; often the wife touches the husband’s arm or holds a blade of kuśa grass linked to him during offerings.

In many rites the wife sits to the husband’s right, and in some to his left; the priest or your family custom will guide you.

For daily pūjā, there is no rule that both must be present. Whoever is available does it on behalf of the household, and either partner’s worship blesses the whole home. Praying together when you can is a beautiful way to strengthen a marriage.

Tradition, as told in the Uttara Kāṇḍa of the Rāmāyaṇa, says that when Śrī Rāma performed the Aśvamedha yajña while Sītā was away, he would not take another wife but had a golden image of Sītā placed beside him, because a householder’s great rite needs his partner at his side.
