The Company is incorporated under the laws of the Commonwealth of Pennsylvania. The Pennsylvania Business Corporation Law of 1988, as amended (the “BCL”), contains provisions for mandatory and discretionary indemnification of a corporation’s directors, officers and other personnel and related matters.

Sections 1741 and 1742 of the BCL provide that a corporation may indemnify its representatives (including directors and officers) against expenses, judgments, fines and amounts paid in settlement that they incur in such capacities, provided certain standards are met, including good faith and the reasonable belief that the particular action is in, or not opposed to, the best interests of the corporation or, in a criminal proceeding, that such representatives had no reasonable cause to believe their conduct was unlawful. In the case of actions against a director or officer by or in the right of the corporation, the power to indemnify extends only to expenses actually and reasonably incurred in connection with the defense or settlement, and such power generally does not exist if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation, unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses. Under Section 1743 of the BCL, a corporation is required to indemnify directors and officers against expenses they may incur in defending actions to which they are made a party by reason of their status as such if they are successful on the merits, or otherwise, in the defense of such actions. Under Section 1745 of the BCL, a corporation may pay the expenses of a director or officer incurred in defending an action or proceeding in advance of the final disposition thereof upon receipt of an undertaking from such person to repay the amounts advanced, if it is ultimately determined that such person is not entitled to indemnification from the corporation.

Section 1746 of the BCL provides that the foregoing provisions shall not be deemed exclusive of any other rights to which a person seeking indemnification may be entitled under, among other things, any provision in the corporation’s articles of incorporation or bylaws, provided that no indemnification may be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.

Article 9 of the Company’s articles of incorporation provides that we will indemnify and hold harmless, to the full extent permitted by law, each person who was or is made a party or is threatened to be made a party to or is otherwise involved in (as witness or otherwise) any threatened, pending or completed action, suit, or proceeding, whether civil, criminal, administrative or investigative and whether or not by or in the right of the Company or otherwise (hereinafter, a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the heir, executor or administrator, is or was a director or executive officer of the Company or is or was serving at the request of the Company as a director, officer or trustee of another corporation or of a partnership, joint venture, trust or other enterprise (including without limitation service with respect to employee benefit plans), or where the basis of such proceeding is any alleged action or failure to take any action by such person while acting in an official capacity as a director or executive

officer of the Company, or in any other capacity on behalf of the Company while such person is or was serving as a director or executive officer of the Company, against all expenses, liability and loss, including but not limited to attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid or to be paid in settlement (whether with or without court approval), actually and reasonably incurred or paid by such person in connection therewith. The right to indemnification is a contract right and includes the right to be paid by the Company the expenses incurred in defending any such proceeding (or part thereof) or in enforcing his or her rights to indemnification in advance of the final disposition thereof promptly after our receipt of a request therefor stating in reasonable detail the expenses incurred; provided, however, that to the extent required by law, the payment of such expenses incurred by a director or executive officer of the Company in advance of the final disposition of a proceeding shall be made only upon receipt of an undertaking, by or on behalf of such person, to repay all amounts so advanced if and to the extent it shall ultimately be determined by a court that he or she is not entitled to be indemnified by the Company.

The Company’s articles of incorporation also provide, as authorized by Section 1713 of the BCL, that a director of the Company shall not be personally liable for monetary damages as such for any action taken, or any failure to take any action, unless: (1) the director has breached or failed to perform the duties of his/her office under Subchapter B of Chapter 17 of the BCL (relating to standard of conduct and justifiable reliance); and (2) the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. This limitation on the personal liability of directors of the Company does not apply to: (A) the responsibility or liability of a director pursuant to any criminal statute; or (B) the liability of a director for the payment of taxes pursuant to local, state or federal law.

As authorized by Section 1747 of the BCL, the Company has obtained and maintains insurance policies covering its officers and directors and indemnifying them against loss on account of certain claims made against them, within the limits and subject to the limitations of such policies.

At present, there is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

Not applicable.

Moon Township, Pennsylvania 15108

Ladies and Gentlemen:

We have acted as counsel to Mastech Digital, Inc., a Pennsylvania corporation (the “Company”), in connection with the preparation of the Registration Statement on Form S-8 (“Registration Statement”) to be filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended, relating to the registration by the Company of 600,000 shares (the “Shares”) of the Company’s common stock, par value $.01 per share (“Common Stock”), issuable pursuant to the Mastech Digital, Inc. 2019 Employee Stock Purchase Plan (the “Plan”). This opinion is furnished pursuant to the requirements of Item 601(b)(5) of Regulation S-K.

Although as counsel to the Company we have advised the Company in connection with a variety of matters referred to us by it, our services are limited to specific matters so referred. Consequently, we do not have knowledge of many transactions in which the Company has engaged or its day-to-day operations.

In rendering this opinion, we have examined the following documents: (i) the Company’s Amended and Restated Articles of Incorporation; (ii) the Company’s Amended and Restated By-Laws; (iii) resolutions adopted by the Company’s Board of Directors related to the Plan; (iv) the Registration Statement (including all exhibits thereto); (v) the Plan; and (vi) a certificate from an officer of the Company. We have not made any independent investigation in rendering this opinion other than the document examination described. We have assumed and relied, as to questions of fact and mixed questions of law and fact, on the truth, completeness, authenticity and due authorization of all certificates, documents and records examined and the genuineness of all signatures.

In rendering this opinion, we have assumed that at the time of issuance of any Shares, there shall be a sufficient number of duly authorized and unissued shares of the Company’s Common Stock to accommodate the issuance of the Shares.

This opinion is limited to the laws of the Commonwealth of Pennsylvania.

Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized by the Company and, when issued and delivered by the Company in the manner and on the terms described in the Plan, will be validly issued, fully paid and non-assessable.

This opinion is given as of the date hereof. We assume no obligation to update or supplement this opinion to reflect any facts or circumstances which may hereafter come to our attention or any changes in laws which may hereafter occur.

This opinion is strictly limited to the matters stated herein and no other or more extensive opinion is intended, implied or to be inferred beyond the matters expressly stated herein.

We consent to the filing of this opinion as an exhibit to the Registration Statement.

Exhibit 23.1

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We hereby consent to the incorporation by reference in this Registration Statement on Form S-8 of our report dated March 23, 2018, relating to the consolidated financial statements and financial statement schedule of Mastech Digital, Inc., appearing in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.
