Principal Engineer
Aleph · Madrid, ES
. Javascript API PHP Python TypeScript Google Ads
Are you ready to join our digital revolution journey?
At Aleph , we’re not just part of the digital advertising landscape—we’re shaping its future. Representing the world’s leading platforms, including TikTok, Amazon, Google, and nearly 55 others, we operate in 130+ markets across new and existing geographies.
Our mission is to empower advertisers and brands to unlock the full potential of these platforms' advertising capabilities. By fostering long-lasting partnerships, we create limitless opportunities for people and businesses to advertise effectively at both local and global levels.
With a presence spanning continents, Aleph offers you the chance to be part of a fast-growing, innovative team where your work makes a direct impact. If you’re ambitious, forward-thinking, and eager to thrive in a dynamic, global environment, Aleph is the perfect place to build your career.
About The Role
We're an advertising company that lives or dies by how well we connect to the outside world. We integrate with the major social and ad platforms (Meta, Google, TikTok, LinkedIn, Snap, and more) and wire them into our internal systems for billing and reporting. Data moves constantly and in both directions, at scale, and a meaningful part of our estate is legacy. You'll own the technical direction that keeps all of this coherent, resilient, and evolvable — and you'll stay close enough to the code to prove it.
This is the top of our individual-contributor ladder. You won't have direct reports; your leverage comes from setting direction, building the hard parts yourself, writing the decisions down, and getting engineers and leadership to build behind them. This is not a role that only draws diagrams — you'll ship production code on the riskiest paths, cut the spike that de-risks a migration, and go deep in the incidents nobody else can crack. We work across PHP, Go, Python, TypeScript, and JavaScript; PHP and Go are both first-class and here to stay, and the right tool for a problem can land in either. You'll be the person who decides where new capability lands, how legacy gets retired, and how we absorb the constant churn of third-party APIs without breaking delivery.
What You'll Own
- The integration architecture for ingesting from and pushing to external ad/social platforms — versioning, rate limits, backfills, idempotency, webhooks, and graceful degradation when a partner API changes underneath us.
- The data architecture for information flowing between platforms and internal systems: pipelines, reconciliation, contracts between services, and the path from operational data to reporting.
- A pragmatic strategy for modernizing the legacy estate — strangler-fig migrations, clear service boundaries, and sound judgement about which language and pattern fit each problem — carried far enough into code that teams can follow the pattern.
- The engineering bar for integration and data work: the reference implementations, patterns, and standards the org builds against, ratified through the technical committee.
- Set the technical direction for new products and major changes, and stay the technical decision-maker through build and post-launch — with the authority to course-correct when implementation drifts, and the habit of being in the codebase to catch the drift early.
- Build the hard parts yourself. Write production code on the riskiest, highest-leverage paths; prototype the uncertain approach to turn an argument into evidence; build the reference implementation others extend.
- Turn intangible trade-offs — partner API risk, team capability, long-term scalability, cost of change — into clear, written decisions (ADRs) that leadership and the technical committee can sign off on.
- Define service and data contracts, integration patterns, and resilience strategies that survive third-party API deprecations and outages.
- Go deep when it breaks: lead diagnosis on the gnarliest production incidents and performance regressions, and land the fix and the systemic follow-up.
- Identify the infrastructure (compute, data, messaging, observability) needed to meet current and near-future goals.
- Raise the bar through others: mentor engineers and tech leads, set the standard in code review, and drive cross-functional decisions across engineering, product, security, and operations — through influence, not line management.
- Evaluate third-party and vendor solutions against our integration and data requirements.
- Monitor systems against performance and business benchmarks and escalate with concrete recommendations.
- Substantial experience as a staff/principal engineer (or equivalent) on integration-heavy, data-heavy systems — ideally where you didn't control the external APIs.
- Still hands-on. You lead by building, and you're demonstrably strong in production code, not only in design.
- Depth in at least one of PHP, Go, or Python, and comfort across a polyglot estate (TS/JS on the front).
- A track record of modernising legacy systems incrementally without halting delivery.
- Fluency in integration and data patterns: idempotency, eventual consistency, rate limiting, queuing, backfills/reconciliation, API versioning.
- A history of driving technical decisions through influence rather than authority — getting senior leadership and peer engineers to commit to a direction, and backing it with working code.
- Experience with ad/martech platform APIs (Meta Marketing, Google Ads, TikTok, etc.).
- Data warehouse / analytics pipeline experience (e.g. BigQuery).
- Multi-region, multi-currency, or high-volume billing/reconciliation backgrounds.
Aleph is a place of many cultures, perspectives, and talents. We support each other, creating an environment of giving and receiving. We value partnership and communication because we believe it takes a group of people to achieve great things. We are energized by our ever-changing industry, our curiosity keeps us learning and seeking out new opportunities.

We are looking for a skilled Senior FullStack Developer who is ready to take on a Team Lead position soon and join an exciting and complex project.
Description: An AI-powered platform for managing users, roles, and permissions. It handles identity verification (KYC/KYB), a rewards/points system, and connects with CRM, accounting, and card-issuing tools. It's genuinely complex - not just a simple database app.
English Proficiency: Upper-Intermediate / B2+ (client-facing communication required)
Team: Project Manager, Product Designer, 2 FullStack developers, Support Engineer.
Expected Working Hours: Full-time, 40 hours/week.
Location: Remote, Europe only. Preference for Western Europe (occasional on-site visits may be required); candidates from Eastern Europe will also be considered.
Engagement Duration: 6–12+ months (long-term).
Technology Stack
- Next.js 15 (App Router) + TypeScript, tRPC
- PostgreSQL + pgvector via Drizzle ORM, Zod
- NextAuth.js + Keycloak (OIDC/OAuth2)
- Tailwind + shadcn/ui
- Docker, Azure Container Apps, Terragrunt + GitHub Actions
- Schema/metadata-driven system design (this project uses per-role schema overlays across 11 distinct roles, not off-the-shelf RBAC).
- JSONB-based PostgreSQL modeling.
- Strong code review instincts around authorization/access control.
- Integrating multiple third-party APIs with graceful handling of partial failures.
- DevOps-adjacent comfort (Docker, IaC, CI/CD, Azure).
- Own architectural decisions for a large, actively evolving codebase in a compliance- and finance-sensitive domain (KYC/KYB, points/rewards economy, card issuance).
- Extend the generic-entity/schema system without regressions.
- Lead integration work with external providers (SmartSearch, Salesforce, Xero, Pannovate, SendGrid).
- Review code with a security-first eye, particularly on permission/access-control gaps.
- Maintain the project's Memory Bank and feature-level documentation practices.
- Participate in on-call/production support.
- Responsible for managing the DevOps part of the project
- As the role matures, mentor other engineers and set technical guardrails for non-engineering contributors working directly in the codebase via AI tools.
