We are unable to sponsor or take over sponsorship of an employment visa at this time.\nMark43’s mission is to empower communities and their governments with new technologies that improve the safety and quality of life for all. We build powerful, scalable, and elegant software that sets a new standard for the tools upon which our first responders rely. Our users are diverse, and we are therefore committed to embracing diversity of thought and experience within our team. \nThe Role\nMark43 is hiring its first dedicated Tax Manager to own direct and indirect tax across our U.S., U.K., and Canadian entities. You will be the internal owner of every tax filing, payment, and position the company takes. You will manage our third-party advisors and treat them as an extension of the team, not a substitute for internal ownership. Beyond compliance, we want someone who actively looks for ways to reduce our tax exposure and cash tax cost, and who can build processes that will hold up through audit and IPO readiness. \nThis role also owns all financial transparency reporting for a significant U.K. public-sector contract governed by the U.K. government’s Open Book Data requirements. Under these requirements, Mark43 must provide the government customer full visibility into the costs, pricing, and margin behind the services it delivers. \nWhat You'll Do \nTax compliance and reporting: \nOwn U.S. federal and state income tax compliance in partnership with external advisors, including tax attribute tracking and international reporting for our foreign subsidiaries. \nOwn U.S. sales and use tax, including collection and remittance, exemption certificate management for our government agency customers, and nexus monitoring. \nLead the design and rollout of a multi-state use tax apportionment approach for software purchases to reduce our sales tax cost. \nOwn corporation tax, VAT, GST/HST, and statutory filings for our U.K. and Canadian subsidiaries. \nManage our transfer pricing framework for our cost-plus entities, including intercompany agreements and documentation. \nPrepare or review the quarterly and annual ASC 740 tax provision and support the external audit on tax matters. \nOwn Open Book Data reporting on a major U.K. public-sector contract, including periodic reporting to the customer, responding to inquiries, and leading any audits. \nIdentify opportunities to reduce tax exposure and cash tax cost, and advise leadership on the tax implications of new contracts, jurisdictions, and acquisitions. \nManage third-party tax advisors and build scalable, well-documented processes and controls. \nProactively identify opportunities to reduce tax exposure and cash tax cost across all jurisdictions, and bring well-supported recommendations to leadership. \nU.K. Open Book Data Reporting \nOwn Open Book Data reporting for a major U.K. public-sector contract. This includes maintaining the contract financial model and reconciling actual costs, revenue, and margin to it. \nPrepare and submit periodic Open Book reports to the customer authority within contractual deadlines. \nAct as the primary finance point of contact for the customer's financial inquiries, and lead the response to any audits or reviews exercised under the contract's audit rights. \nWork with the commercial, delivery, and accounting teams to ensure costs are captured and allocated at the level of detail Open Book reporting requires. \nWhat You Bring \n6+ years of progressive tax experience, ideally including time at a Big 4 or national accounting firm and time in-house at a multinational company. \nCPA (U.S.), CTA or ACA (U.K.), or CPA (Canada), or an equivalent professional qualification. \nHands-on experience with both direct and indirect tax across more than one country. Exposure to the U.S., U.K., and Canada is strongly preferred. \nSolid working knowledge of U.S. sales and use tax as it applies to SaaS and digital products, including multi-state sourcing and apportionment. \nExperience with ASC 740 tax provisions and with supporting financial statement audits. \nWorking knowledge of transfer pricing for cost-plus service arrangements. \nComfort managing outside advisors, holding them to deadlines and quality standards, and challenging their conclusions when warranted. \nA track record of finding and executing tax savings opportunities, not just maintaining compliance. \nStrong analytical and Excel skills. Experience with NetSuite and sales tax automation tools is a plus. \nNice to Have \nExperience with U.K. public-sector contracts, Open Book Data, or government contract cost accounting. \nExperience in a venture-backed or pre-IPO company. \nFamiliarity with government and tax-exempt customer bases \nLocation\n\nMust be located in New York, Boston or London.\nMark43 is approved to hire in Canada, the UK, and 36 U.S. states, including Alabama, Arizona, California (excluding San Francisco), Colorado, Connecticut, Washington D.C., Florida, Georgia, Iowa, Idaho, Illinois, Indiana, Kansas, Massachusetts, Maryland, Maine, Michigan, Minnesota, Missouri, North Carolina, Nebraska, New Hampshire, New Jersey, New Mexico, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Vermont, Washington, Wisconsin, and West Virginia.
