The posting

_Please do not contact us or apply if you are a recruiter, consultant, or outsourcing company.

_**Join a team of fintech heroes! 🚀

**Performativ is changing the way investment advisors and financial institutions operate. We are building a modern platform for portfolio management, reporting, compliance, trading, and client engagement, replacing fragmented systems, manual workflows, and technology built for another era.

Our platform depends on accurate and timely data from custodians, banks, brokers, and other financial institutions. These connections provide the positions, transactions, cash movements, instruments, and corporate actions used throughout the investment-management lifecycle.

You can read more about our product at performativ.com.

**As our new Software Engineer, Investment Data Integrations 📈

**You will help build and operate the systems that connect Performativ with custodians and other providers of investment data.

The immediate challenge is practical: we need to deliver a growing number of integrations while maintaining the existing portfolio and resolving real production issues. The longer-term challenge is to avoid a scaling trap where every new institution requires another collection of manual processes and bespoke code.

We are building a more automated integration platform with reusable pipelines, mappings, reconciliation, quality controls, and AI-assisted development. Your work will contribute both to integrations customers need now and to the foundations that let the team deliver future integrations faster and more safely.

  • You will develop and maintain integrations covering positions, transactions, cash, instruments, prices, corporate actions, and other investment data across files, APIs, SFTP, and message-based interfaces.
  • You will build reusable ingestion, transformation, validation, reconciliation, and monitoring capabilities instead of treating each provider as an isolated implementation.
  • You will investigate complex data and production issues across internal systems, external providers, and customer environments, then deliver permanent fixes that prevent known classes of problems from recurring.
  • You will work closely with users, operations specialists, and other engineers to understand the complete workflow and ensure that integrated data is correct and useful throughout the platform.
  • You will direct AI agents to produce much of the implementation, review their assumptions and output critically, and establish the tests, controls, and evidence required for safe deployment.

You should bring strong backend or data-engineering judgment and experience with production systems where correctness and reliability matter. Experience with financial integrations, investment data, reconciliation, ETL pipelines, APIs, structured files, or regulated systems would be valuable. Familiarity with technologies such as Python, Golang, PHP, TypeScript, MySQL, Redis, AWS, and CI/CD tooling is useful, but experience with our exact stack is not essential.

**We value your passion 🔥

**At Performativ, we are builders first. We have ambitious goals and value the time, judgment, and effort people put into their work. You will be trusted to make your mark and help shape how we solve difficult problems.

We do not divide the platform into personal territories. People develop deeper context in different areas, but we solve problems as a team. We expect people to lead when appropriate, follow through on what they take on, contribute to the work of others, and help teammates succeed.

AI can help us understand formats, generate mappings, develop implementations, and test integrations faster. It does not replace financial-domain understanding, careful validation, or accountability for the resulting data.

This role is based in Copenhagen. We work together primarily from our city-centre office, with flexibility to work from home when it makes sense. You should already be based in Copenhagen or be ready to relocate.

**What We Can Offer You 🌱

**

  • Work on integrations at the centre of a production wealth-management platform.
  • Solve difficult problems involving financial data, external systems, reconciliation, reliability, and operational workflows.
  • Help create an AI-assisted approach to developing and maintaining integrations safely at scale.
  • An ambitious, collaborative team with experience from leading technology companies, consultancies, and financial institutions.
  • Strong opportunities to deepen both your engineering capabilities and your understanding of investment management.

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.
