The posting

SEON is the command center for fraud prevention and AML compliance, helping thousands of companies worldwide stop fraud, reduce risk and protect revenue. Powered by 900+ real-time, first-party data signals, SEON enriches customer profiles, flags suspicious behavior and streamlines compliance workflows - all from one place. SEON provides richer data, more flexible and transparent analysis, and faster time to value than any other provider on the market. We’ve helped companies reduce fraud by 95% and achieve 32x ROI, and we’re growing fast, thanks to our partnerships with some of the world’s most ambitious digital brands like Revolut, Wise, and Bilt.

You will join SEON's Engineering team, reporting to the Director of Engineering. As a Staff Software Architect, you will embed with our Customer Platform and Scoring engineering teams, helping define feasibility during product research and shaping the technical vision.

Together these teams own the path a customer request follows through SEON: the platform customers configure and use, and the scoring engine that turns SEON’s vast dataset into a decision. Architectural challenges include multi-tenant isolation, integrating external data vendors within cost and latency limits, low-latency rule and model evaluation, scaling applications, and privacy and consent constraints on shared data.

Location: Budapest, hybrid

WHAT YOU’LL DO:

- Embed in the daily life of up to three engineering teams: Customer Platform (customer-facing applications, APIs, tenant management and provisioning) and Scoring (rules, scoring models and real-time decisioning).

- Ensure that all initiatives delivered by the teams have a technical design which is in-line with SEON's architectural best-practices, pragmatic (solves the right problems without being overly complicated), and complete and precise (covering all necessary aspects without loose ends).

- Ensure that security, scalability, and compliance are built into the foundation of all technical designs.

- Collaborate with the Tech Lead and Product Managers of the teams to identify the right ways to solve business problems.

- Deliver proof-of-concept solutions to demonstrate potential technical directions to take.

- Support the estimation effort during the initiative planning phase.

- Contribute to the delivery of initiatives via hands-on work when needed.

- Act as a technical mentor to the engineers within the Customer Platform and Scoring teams, elevating the overall engineering standards and practices.

- Surface recurring architectural challenges to the centralized Architecture team and contribute to company-wide solutions to those problems.

- Document design decisions in the form of Architecture Decision Records.

- Own the design of the interfaces between the three teams, such as the contract between enrichment data and scoring rules, so that changes in one team do not break the others.

- Occasionally support the revenue organization and customers when technical challenges like high-load events arise.

WHAT YOU’LL BRING:

- Strong working knowledge of modern web development technologies, specifically TypeScript, Java, and Python.

- Experience with distributed system design.

- Experience designing and scaling high-throughput, low-latency distributed systems.

- Strong understanding of how web services and SaaS applications work.

- Experience designing multi-tenant SaaS platforms, including tenant isolation, provisioning, and configuration management.

- Experience integrating third-party data providers and APIs, and designing around their cost, latency, and reliability limits.

- Experience with real-time decisioning systems, such as rules engines, feature computation, or machine learning model serving.

- Expertise with Amazon Web Services (AWS).

- Experience with relational databases (specifically PostgreSQL or YugabyteDB).

- Experience with modern DevOps tools, particularly Kubernetes, Terraform, and ArgoCD.

- Strong understanding of data security best practices and designing systems that comply with strict data privacy standards (e.g., GDPR).

- Strong organizational skills and ability to work together with both technical and non-technical stakeholders.

- Experience and continuous curiosity on utilizing AI tools to improve engineering practices and SEON’s product

- Ability to work independently, prioritize your workload.

- Excellent written and verbal English communication skills.

AMAZING IF YOU ALSO HAVE:

- Familiarity with the fraud prevention, AML, KYC, or cybersecurity domains is a strong advantage.

- Experience with Kafka and Flink is a plus.

- Experience with analytical or columnar databases, such as ClickHouse, is a plus.

- Experience with multiple database/search technologies, specifically Elasticsearch is a plus.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
