The Team Lead plays a critical role in Kraken’s engineering organisation. You will work closely with the team's Product Manager to guide product development through informed prioritisation and product objectives.
You’re expected to balance:
- Operational effectiveness
- Team support and wellbeing
- Strategic product alignment
- Technical leadership
This role is about building a high-functioning team, shipping and maintaining high-quality systems, and keeping Kraken’s culture strong as we scale.
Core Responsibilities
-
1. Leadership & Communication
- Represent the team upward and outward with confidence
- Communicate proactively, clearly, and respectfully
- Keep the team informed about priorities and changes
- Advocate for your team while challenging constructively
-
2. Team Management & Support
- Stay aware of team capacity, stress, and wellbeing
- Run 1:1s and offer coaching and mentorship
- Nurture a collaborative, motivated team culture
- Make and carry out difficult decisions for the good of the team and Kraken
-
3. Product & Delivery Oversight
- Align the team to product vision and long-term goals

4. Strategic Decision-Making
- Make resource and prioritisation trade-offs
- Contribute to hiring and talent development

5. Operational Excellence

What Makes a Great Team Lead?
- A strong Lead Software Engineer at Kraken demonstrates:
- Clear, regular communication
- Strategic thinking and the ability to translate that to action
- Advocacy for their team and its products
- A commitment to mentorship and support
- Strong organisational habits
What This Role Isn’t - This isn’t about doing everything yourself. It’s about enabling the team — scaling through delegation, coaching, and systems. Your value comes from what the team delivers, not just your personal output.

- Python
- Django

- Celery and async processing
