Solve Complex Infrastructure and ML Problems : Address complex infrastructure and machine learning challenges that span the organization. Analyze systems to identify and rectify bottlenecks, inefficiencies, and areas for improvement.

Drive Model Evaluation and Optimization : Lead the development of model evaluation frameworks, optimize data pipelines, and implement continuous training strategies to ensure that models remain accurate and up-to-date.

Apply ML Expertise to Fintech : Leverage state-of-the-art machine learning models within the fintech domain to automate and enhance document processing.

Collaborate Across Teams : Work closely with stakeholders from Product, Engineering, and Operations to ensure that goals are aligned and that execution is coordinated and effective.

Mentor and Guide Engineers : Provide mentorship to engineers within both ML and platform teams, fostering their professional development and contributing to the overall growth of Ocrolus' technical expertise. Coach and influence others to improve company culture.

Contribute to Engineering Standards : Play an active role in shaping Ocrolus-wide engineering standards, participate in design reviews (RFCs / ADRs), and promote adherence to best practices. Champion Code Quality and Reliability : Be a vocal advocate for code quality, observability, and system reliability. This includes everything from implementing rigorous A / B testing to setting up real-time monitoring systems.

Understand how their team and projects fit into the larger business goals. Bring together technical and nontechnical stakeholders towards common objectives, suggest alternative solutions to customer problems, and help teach and support more junior teammates.

Look for opportunities for process improvements within their team and works with others to implement process changes.

Find ways to incorporate company values into day-to-day decisions and have ideas on how to build policies / processes that support the improvement of company culture.
