Integration Engineer

Sherpas; Zaragoza; Presencial; EUR 60.000 - 90.000; Jornada completa

Descripción de la vacante

Sherpas is seeking an Integration Engineer to design and maintain connectors for custodial data, CRM, and financial planning tools in Zaragoza, Spain. The role focuses on making onboarding configurable, not code-based, so customers can self-serve where possible.

You will own data reconciliation, handle integration failures gracefully, and build tooling to empower non-engineers. Strong Python/SQL and frontend skills are required.

Formación

• Backend engineer with real integration scars from undocumented, inconsistent, rate-limited APIs.
• Experience handling failure modes: retries, partial data, silent changes, reconciliation breaks.
• Strong Python and SQL; ability to build tooling for others.
• Experience turning onboarding into a self-serve product.
• Frontend skills to enable configuration UI.

Responsabilidades

• Build, maintain and harden connectors for custodial data, CRM and planning tools.
• Ensure data reconciles; upstream figures must be accurate and auditable.
• Turn bespoke onboarding into standard configuration, reducing engineering work.
• Protect the product roadmap by preventing onboarding delays.

Descripción del empleo

Every firm we onboard arrives with its own custodian, its own CRM and its own back office app. Today each of those is bespoke work. Your job is to make it configuration — so the eleventh firm takes hours rather than the days the first one took.

The role

The real deliverable is not connections built. It is connections a non-engineer can configure. You succeed when you are no longer needed for the standard case — which is an unusual thing to ask of a role, and the reason it is interesting.

What you will own

• The connectors: custodial data, CRM, financial planning tools — building them, maintaining them, and making them resilient to the ways external systems misbehave.
• Data that reconciles. In wealth management a wrong number is a regulatory problem, not a bug, and your connectors are upstream of every figure the platform produces.
• Turning the bespoke into the standard: configuration over code, so onboarding stops being an engineering project.
• Protecting the roadmap. Without this role, onboarding work lands on whoever is nearest and product development stops.

What we are looking for

• Backend engineer with real integration scars — you have worked with third-party APIs that were undocumented, inconsistent, rate-limited, or all three.
• You think about failure modes first: retries, partial data, silent schema changes, reconciliation breaks.
• Strong Python and SQL.
• You build tooling for other people instinctively rather than keeping the knowledge in your head.
• Financial data — custodial feeds, positions, transactions, performance. If you have handled these, say so early.
• Experience turning a services-heavy onboarding into a self-serve product.
• Frontend skills. Someone else builds the configuration UI; you make it possible.

What success looks like

• Engineering hours per firm onboarded trend down, onboarding after onboarding.
• A growing share of new firms are served by connectors that already exist.
• Time to first reconciled data set shrinks to something we can promise a client.

How we hire

• A conversation about the worst integration you have dealt with and what you did about it.
• A paid practical exercise against a realistic messy data source.
• A working session with our engineering team.
