SRE Lead (f/m/d)

SRE Lead (f/m/d) Upvest is on a mission to make investing as easy as spending money. The company empowers businesses to offer a wide range of investment products and the best experience in the field of capital market investment and retirement planning. Upvest’s Investment API is easy to integrate so that fintechs and enterprises alike can save resources and fully focus on their core business.‍ Upvest is one of the few fintechs in Europe that can provide its B2B clients with the full range of investment opportunities in the areas of principal broking business, proprietary trading, and safe custody business for traditional securities. The company was founded in 2017 by Martin Kassing and currently employs more than 200 people across Europe. Its latest €100m fundraising round (Series C) was led by Hedosophia and Sapphire Venture, with continued support from existing investors including Bessemer Venture Partners, BlackRock, Earlybird, HV Capital, Motive Ventures, and Notion Capital. We currently employ 240+ people across Europe with our headquarters based in Berlin, Germany, and hubs in Tallinn, Estonia, and London, UK. We would consider hiring a hybrid setup with regular travels to Berlin for this role. THE OPPORTUNITY Reliability isn't just a metric for us. It's the foundation of everything we build. As Upvest scales at breakneck speed, we're raising the bar: establishing a dedicated SRE function to ensure our best-in-class reliability standards evolve as ambitiously as our platform. This is your chance to define what world-class reliability looks like for a market-leading, high-growth fintech platform. You won't inherit legacy processes or fight bureaucracy. You'll architect the reliability culture, standards, and practices that will carry us through the next phase of rapid growth. If you've ever wanted to build an SRE practice the right way this is that moment. THE ROLE Forget firefighting. You're here to prevent the fires from ever starting. As SRE Lead, you'll be part technical visionary, part organizational catalyst. You'll embed reliability into the DNA of how we build, partner with engineering teams to shift left on observability and resilience, and create the frameworks that let us move fast and stay stable. Your team won't own services, you'll elevate everyone who does. This is influence at scale. You'll shape how engineering leaders think about reliability, how product managers balance features against stability, and how our entire organization defines "production-ready." You'll build and mentor a lean, exceptional team of 2-4 SREs who will become force multipliers across the company. What you'll build: - Reliability as Code: establish SLOs, SLIs, and error budgets that become the shared language of engineering velocity and stability - Proactive Defense: design chaos experiments, redundancy patterns, and failover strategies that validate resilience before customers ever see an issue - Incident Excellence: transform how we respond to and learn from incidents, turning chaos into confidence through world-class runbooks and post-mortem culture - Performance Engineering: drive load testing, benchmarking, and architecture reviews that ensure we can handle 10x our current scale - Automation Leverage: eliminate toil ruthlessly. Build tools that let engineers focus on value, not repetitive operational drudgery - Defensive Architecture: define the principles and patterns (circuit breakers, bulkheading, graceful degradation, intelligent rate limiting) that make our services antifragile - Stress at Scale: validate system behavior under synthetic load and adversarial conditions, proving our defenses work before attackers or traffic spikes test them WHO YOU ARE You're not just experienced, you're battle-tested. You've been on-call when things broke spectacularly. You've rebuilt systems that couldn't scale. You've turned "hope it works" into "we know it works." And now you want to prevent the next generation of en ... (truncated, view full listing at source)
