Backend Engineer - Team Atlas

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.

Responsibilities

Build and operate backend services in Python on AWS — Lambda functions, DynamoDB, Aurora, and event-driven pipelines that handle real production traffic; 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 5 years of professional software engineering experience, with a proven track record of leading complex projects in a senior capacity (2+ years); Deep expertise in Python and 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; 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

Nice to have

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)

Benefits

Work with colleagues that lift you up, challenge you, celebrate you and help you grow; Experience a truly flat hierarchy and communicate directly with founding team members; Learn from experienced mentors and achieve tremendous personal and professional growth; 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
