About the role:

Upvest is looking for a Senior Site Reliability Engineer to raise the bar on how we build, run and recover our systems. Our platform sits in the critical path for our clients and their end customers and as we scale reliability and availability become more crucial.

In the near term, you’ll focus on three things: eliminating toil, improving incident management and observability. That means establishing the standards through automation and guardrails that make good engineering the default, turning our incident process into a robust and effective practice, and giving every team the telemetry to see what their services are doing in production.

Over time, your scope grows into resilience architecture, chaos engineering and disaster preparedness - making sure our systems degrade gracefully and that we find weaknesses before our clients do.

You’ll work closely with product engineering teams, embedding SRE practices into how they design, ship and operate, and mentoring engineers along the way. If you like the idea of setting technical direction for reliability across an organisation, and you measure your success by how rarely anyone has to think about you at 2am, this is the role for you.

Responsibilities

• Incident Excellence : transform how we respond to and learn from incidents, turning repeat problems into opportunities through robust runbooks and post-mortem culture.
• Reliability as Code : establish SLOs, SLIs, and error budgets that become the shared language of engineering velocity and stability.
• Automation Leverage : eliminate toil ruthlessly. Build tools that let engineers focus on building value for our clients.
• Defensive Architecture : establish SRE principles and patterns (circuit breakers, bulkheading, graceful degradation, intelligent rate limiting) to make our services resilient.
• Stress at Scale : validate system behavior under synthetic load and adversarial conditions, proving our defenses work to improve disaster preparedness.
• Proactive Defense : design chaos experiments, redundancy patterns, and failover strategies that validate resilience before customers ever see an issue.
• What you bring:
• Deep SRE Mastery : years in high-stakes environments (FinTech, payments, banking, trading, mission-critical SaaS) where downtime has real consequences.
• Technical Depth : hands-on expertise with SLOs, incident management, observability, automation, and the discipline of eliminating toil.
• Systems Thinking : you understand resilience architecture deeply and how to design systems that fail gracefully.
• Influence Without Authority : exceptional communication and stakeholder management skills. You can change minds and shape culture through clarity and engineering excellence.
• Leadership : proven ability to mentor engineers, see projects through end-to-end and set technical direction in an engineering organisation.
• It’s great if you have:
• Investment Industry Fluency : understanding our domain means your SRE decisions align with business reality, not just technical ideals
• Stack Familiarity : experience with Golang, Kubernetes, GCP, Postgres, Kafka, or Datadog accelerates your impact
• How we Upvest in you:
• Best-in-class AI tools: Every Upvenger has €20,000 per year to spend on the best AI tools available — so you're always working with the most powerful models and tooling on the market.
• Impact-driven work: We’re building the infrastructure that will power the future of investing in Europe. It’s complex, ambitious, and meaningful. You’ll work with modern technologies and create something entirely new. No legacy systems, no limits.
• Wellbeing: Recharge with 30 days of annual leave and maintain a healthy lifestyle with sports benefits. Access confidential professional coaching and enjoy the flexibility to work remotely abroad for up to 183 days a year. Recharge with UpRest, a one-month fully paid sabbatical after every 4 years of working at Upvest.
• Development: Growth is in our DNA. Each Upvenger has access to a personal development budget and the freedom to decide how to use it.
• Flexible work environment: Work from any of our hubs in Berlin, London or Tallinn hybrid or remotely across Europe, depending on the role. We give you the choice and budget to work where you’re most comfortable and productive, either at home or in the office. You choose.
• Compensation and equity: We believe that all Upvengers contribute to our success and deserve a competitive, above-market salary and a participation in our employee equity program.
• Team celebrations: Participate in company-wide events, such as UpFest, dinners, offsites and our Holiday party, to connect with colleagues and celebrate our achievements.
• Inclusion : We’re committed to a culture where everyone belongs and thrives. Our Employee Resources Groups foster inclusion and connection, like Upfem Black at Upvest, Up&Out, and UpVergent.
• Our Values:
• Make it easy for others. We simplify the complex and act with the best intentions
• Own the outcome. We are proactive, fast and confident to get the job done, valuing progress over perfection.
• Rise to the challenge. We aim high and push the boundaries. We stay curious, learn and celebrate our wins together.
• Tell the story. We start with the Why to align on purpose. We are transparent and share knowledge to empower and inspire others.
• Upvest is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
