Mission statement
The Tech Lead plays a pivotal role in bridging business objectives with technical execution. This role is not purely managerial nor solely individual contributor, but a hybrid position that combines hands-on engineering, architectural leadership, and team enablement. A Tech Lead ensures delivery excellence by actively contributing to the codebase, guiding the team technically, and aligning execution with long-term strategic goals.
At Keyrock, the Tech Lead is a senior technical contributor who drives the implementation and delivery of engineering initiatives within their Business Unit. The Tech Lead is accountable for technical execution and delivery quality, ensuring that systems are built to high standards of reliability, performance, and maintainability.
While the Head of Engineering (HoE) focuses on strategic alignment - ensuring that engineering outcomes meet the broader objectives agreed with the Head of Product (HoP) - the Tech Lead operates as the executional deputy, translating those strategic objectives into code, architecture, and delivery outcomes.
Act as the technical point of accountability for the Service Market Making Business Unit.
Balance strategic thinking with pragmatic delivery, ensuring systems are built to last while meeting immediate needs.
Champion collaboration across teams, ensuring alignment between product, design, QA, and engineering.
Inspire and develop engineers through mentorship, coaching, and technical guidance, fostering growth and autonomy within the team.
Drive Delivery and Alignment: Partner with the Head of Engineering to own delivery of entire work-streams, ensuring architecture and engineering decisions align with both immediate requirements and business strategy.
Balance Code and Leadership: Contribute directly through coding, while also focusing on architecture design, peer reviews, and cross-functional communication.
Mentor and Elevate Engineers: Provide structured feedback through design and code reviews, support skill development, and empower junior and mid-level engineers to take ownership.
Technical Leadership: Guide system design, ensure scalability and resilience, and optimise performance across applications and infrastructure.
Maintain Standards: Uphold engineering best practices, enforce coding guidelines, and partner with QA to embed automation and validation in the delivery pipeline.
Codebase Health: Manage technical debt, lead refactoring initiatives, and ensure long-term maintainability and operational excellence.
Cross-Functional Collaboration: Work closely with product managers, designers, and QA engineers to define scope, refine requirements, and plan delivery in a transparent and predictable manner.
Risk Management: Anticipate technical risks, dependencies, and trade-offs early, and propose mitigations to safeguard delivery timelines.
