Job description

Novatus is a Series B scale-up RegTech SaaS provider and boutique consulting practice, enabling financial services firms to solve complex challenges and redefine what’s possible through expert-led technology and consulting. Across both our technology and consulting services, Novatus delivers practical solutions to some of the most complex regulatory, data and operational challenges in financial services.

Our SaaS platform, En>ACT (short for ensuring more accurate, complete and timely reporting), is a market-leading solution for regulatory transaction reporting and reconciliation, providing real-time, independent oversight of transaction reporting across all global regulatory regimes. En>ACT is the only real-time assurance solution that tests 100% of transactions and 100% of fields, replacing sample-based reviews and static PDF reports delivered months after the event with live, actionable insights. This helps firms remediate quickly, reduce risk, and meet regulatory obligations with confidence. Already trusted by more than 45 firms worldwide, the platform is scalable, proven, and designed for both business and technical users.

Alongside our SaaS offering, our unique model delivers consulting services to solve complex challenges, combining deep expertise, ownership and delivery to create lasting change. Our expertise spans Strategy & Operations, Data & AI, Risk & Resilience, Compliance, Transaction Reporting, and ESG. We embed ourselves within client teams to deliver both insight and execution, taking ownership of outcomes and driving measurable impact.

Since our launch in 2019, we have scaled rapidly, creating space for our people to grow the business. Backed by North American private equity investment, and partnerships with the London Stock Exchange Group and Snowflake’s global data platform, we are shaping the future of financial services through innovation in both consulting and technology. Now a team of 120 globally, our growth plans do not stop here: we are looking for top-tier talent to join us on our journey and enable our next phase of success.

Job Overview

• Experience with a workflow orchestrator (e.g. Airflow, Dagster, or Databricks Workflows).
• Proven system and platform design judgment: you own architectural decisions and can defend the trade-offs. Greenfield, scaling, and migration work all count.
• Comfortable translating complex regulatory requirements into technical specifications.
• Able to own large, ambiguous initiatives and delivering them in incremental, shippable slices.
• Strong communication and collaboration skills, including translating between technical and non-technical stakeholders.
