About the Role
As a key growth accelerator, A11 partners with Europe’s most ambitious startups and scaleups, corporates and SMBs to connect them with top-tier talent ready to make an impact. We’re looking for a hands-on Staff Engineer reporting to the VP Engineering at one of our Ecosystem Companies. You will own the hardest technical problems, set the architecture across teams, and keep a fast-growing trading business fast, correct, and reliable, while still writing code yourself.
Responsibilities
- Set the technical direction across teams: define the target architecture, write the RFCs behind big decisions, and ensure teams build towards the same picture.
- Lead the hardest technical work yourself, from design to production, instead of only advising on it.
- Shape the carve-out of our transaction core from Salesforce into a modern, modular core system, with a migration path that never disrupts daily trading.
- Make reliability, security, and observability part of how we build: monitoring, alerting, incident response, and postmortems that lead to real changes.
- Design how our AI agents act safely on money-touching paths, with evaluations, guardrails, audit trails, and human review where it matters.
- Set standards for correctness and data integrity, including idempotency, validation, and testing, together with QA.
- Mentor engineers through design reviews, pairing, and direct feedback.
- Help us hire by defining what great engineering looks like at the company.
Requirements
- At least 8 years of experience building and running software in production, including systems where errors cost real money.
- Deep backend expertise at production scale in Java or a comparable language such as Kotlin, C#, or Go, and willingness to work in Java and Spring Boot.
- A track record of setting architecture across several teams, through influence rather than a management title.
- Experience designing transactional, distributed, and event-driven systems, with a strong focus on correctness, failure modes, and performance.
- Hands-on depth in reliability, security, and observability, and experience leading incidents and postmortems.
- Experience in a fast-growing company, and a track record of solving business problems, not only technical ones.
- Experience building or evaluating AI agents in production is a strong plus.
- Experience with re-platforming or carving out systems from a platform like Salesforce or an ERP is a plus.
