Senior Backend Engineer - Team Atlas

Location: Berlin Office; Iasi Office; London Office; Dublin Workplace: Hybrid ABOUT THE ROLE Banks and fintechs use Taktile to automate critical decisions, like credit and risk, in real time. We're building the infrastructure that makes financial institutions truly AI-native, and the backend is where the hard problems live. We're growing rapidly with enterprise customers across banking and insurance, and we're looking for a Senior Backend Engineer to join Team Atlas : a small, high-ownership team focused on the data infrastructure powering our feature computation platform. You'll own critical systems end-to-end, and your decisions will shape the product. WHAT YOU'LL DO - Build and operate backend services in Python on AWS — Lambda functions, DynamoDB, Aurora, and event-driven pipelines that handle real production traffic. You'll leverage agentic AI tools as part of your daily workflow. - Tackle hard backend problems — latency, reliability, and scale are everyday concerns. - Own your systems end-to-end: from architecture and implementation to deployment, monitoring, and incident response. - Make key architectural decisions — you'll have real authority over how things are built, not just what gets built. - Raise the bar for the team through code reviews, mentoring, and improving our development tooling and processes. - Work directly with Product and Design to shape what we build next. REQUIREMENTS - At least 7 years of professional software engineering experience, with a proven track record of leading complex projects in a senior capacity (2+ years). - Deep expertise building backend systems on cloud platforms, we use AWS. - Strong system design skills — you're comfortable making architectural trade-offs and defending them. - Depth in at least one of these areas: data pipelines and storage, event-driven architectures, caching and performance, or serverless systems. You don't need all of them. - Strong communication and collaboration skills, with the ability to align technical and non-technical stakeholders on a shared vision. - The ability to work in a hybrid model from our Berlin HQ, the London office, or the Iasi hub. Please note that relocation assistance is not provided for this role. IDEAL, BUT NOT REQUIRED - Python, FastAPI, Apache Iceberg, AWS Athena, AWS Glue, or Apache Spark - Streaming / real-time data pipelines (Kinesis) - Multi-level caching strategies (Redis, DynamoDB, in-memory) - Serverless at scale (Lambda, SAM, CloudFormation) OUR OFFER - Work with colleagues that lift you up, challenge you, celebrate you and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields. If you are similarly capable, caring, and driven, you'll find yourself at home here. - Experience a truly flat hierarchy and communicate directly with founding team members. Having an opinion and voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo. - Learn from experienced mentors and achieve tremendous personal and professional growth. Get to know and leverage our network of leading tech investors and advisors around the globe. - Receive a top-of-market equity and cash compensation package. - Get access to a self-development budget you can use to e.g. attend conferences, buy books or take classes. - Receive a new Apple MacBook Pro, as well as meaningful home office set-up. OUR STANCE - We're eager to meet talented and driven candidates regardless of whether they tick all the boxes. We're looking for someone who will add to our culture, not just fit within it. We strongly encourage individuals from groups traditionally underestimated and underrepresented in tech to apply. - We seek to actively recognize and combat racism, sexism, ableism and ageism. We embrace and support all gender identities and expressions, and celebrate love in its many forms. We won't inquire about how you identify or if you've experienced discrimination, but if you want to tell your story, we are all ears.
