Ciklum is looking for a Lead Python Engineer to join our team full-time in Ukraine.
We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.
About the role:
As a Lead Python Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.
Project Description: Client is a fast-growing cybersecurity startup focused on improving reliability and visibility within Security Operations (SecOps) environments. Founded in 2024 and backed by seed funding from Teammate Ventures, is already working with large enterprise customers, including Fortune 500 companies, through successful Proofs of Concept and early commercial engagements.
Client operates in the SIEM (Security Information and Event Management) space, building a platform that helps security teams ensure their detection systems actually work as intended. While SIEM platforms aggregate massive amounts of security data, they often lack visibility into silent failures — such as broken data pipelines, schema changes, or detection rules that stop alerting without notice.
Client addresses this gap by providing deep visibility into SIEM configurations, data sources, processing pipelines, and detection logic. The platform continuously monitors for issues, detects configuration drift, and alerts security teams to problems that could otherwise lead to missed threats and security incidents.
The company is built by experienced security and engineering leaders and operates with a strong startup mindset — valuing ownership, autonomy, and pragmatic problem-solving. Client is scaling rapidly, expanding its engineering team, and building small, independent teams that own features end-to-end while working closely with product and customers.
