Junior Backend Engineer – Data Marketplace

About the role

Taktile is a high-growth, post product–market fit start-up, on a fast trajectory to becoming market leader in the field of automated decisioning.

As a backend engineer starting your career, you will contribute to the expansion and improvement of our Data Marketplace and integration engine. These systems enable customers to access, evaluate, and combine data providers at scale, powering millions of automated decisions every day. Your work will help banks, fintechs, and enterprises fight fraud, expand credit, and enable financial access.

You’ll learn by working alongside experienced engineers on API aggregators, AWS, and complex backend systems, and you’ll grow your skills in building reliable, scalable software. This role is ideal for someone who is motivated to learn quickly, thrives in collaborative environments, and wants to make an impact early in their career.

Taktile is a hybrid company. This role requires working at least 3 days per week from our Berlin HQ.

What you'll do

• Build and maintain backend components in Python on AWS—from integrations to orchestration layers—while learning best practices in code quality, testing, and keeping CI/CD fast and reliable.

• Support outcomes for the Data Marketplace: help onboard providers, implement versioning strategies, and contribute to efforts that reduce time-to-new-integration while maintaining reliability and cost-effectiveness.

• Follow and apply integration standards: learn to work with API contracts/SDKs, resilience patterns (idempotency, retries, backoff), and operational guardrails that scale to millions of daily decisions.

• Collaborate on projects from discovery to production launch—participating in RFCs, validating with prototypes, aligning stakeholders, and contributing to changes with observable impact.

• Improve reliability and performance: support SLOs, instrumentation (tracing/metrics/logging), dashboards, and runbooks while gaining hands-on experience in reducing latency and improving MTTR.

• Grow with mentorship: participate in design reviews, pair programming, and documentation efforts while learning from senior engineers.

• Collaborate in the open: join daily syncs, planning, demos, and deep-dives; work with Product, Security, and Customer teams to turn real-world needs into simple, robust solutions.

Requirements

• Hands-on experience programming in Python (through coursework, projects, or internships).

• Exposure to public cloud environments (AWS preferred).

• Fluency in English, both written and spoken, is essential as we operate in a hybrid environment requiring clear and effective communication.

• Strong foundational knowledge in computer science or software engineering and a passion for simplicity, quality, and ownership.

Ideal, but not required

• Exposure to serverless and event-driven architectures (e.g., Lambda, queues, streams).

• Basic observability practices (tracing, metrics, structured logging).

• Familiarity with AI-assisted development and code generation.

• Fintech domain exposure (KYC, credit bureaus, fraud-prevention APIs).

• Experience with internships, personal projects, or open-source contributions in backend development.
