About the Role

This is where you come in. Below, you’ll find what this role is all about—the impact you’ll drive, the challenges you’ll tackle, and what it takes to thrive at Addi. If you’re ready to be part of something big, keep reading.

What’s the mission you’ll drive

To design and operate the internal engineering platform that makes every developer at Addi radically more productive — delivering africtionless build, test, and observability experience that abstracts infrastructure complexity away from product teams, enabling them to ship high-quality software faster and with greater confidence across our transformation into Latin America's leading financial platform.

What you will do

Compress p95 CI pipeline execution times by 40% within the first 12 monthsby implementing advanced build caching, parallelization, and incremental compilation strategies tailored to our Java/JVM ecosystem ,resulting in a highly optimized developer feedback loop that minimizes context switching and maximizes daily safe deployments per squad.
Deliver100% automated SLO dashboard instrumentation and alert policy coverage for all newly launched and active platform services within the first 6 monthsby embedding automated tracking and error-budget enforcement mechanisms directly into the core platform layer,resulting in product squads seamlessly owning their own operational reliability and shifting on-call accountability closer to code generation.
Establish zero platform-team dependency for production performance triage within the first 9 monthsby operating and standardizing an integrated, continuous observability solution (covering CPU, heap, and thread profiling) across all production JVM services,resulting in product developers independently identifying and resolving application hotspots without escalating tickets to the Platform or SRE teams.
Drive a measurable reduction in platform support ticket volume per developer within the first 12 monthsby shipping native AI-assisted capabilities—specifically automated runbook generation, LLM-based log triage in the developer portal, and compliant service scaffolding—resulting in a highly scalable platform ecosystem where developers get immediate, context-aware operational answers without growing engineering headcount.

What we’re looking for

Deep Expertise in Software Architecture & the JVM Ecosystem
- 3–5 years of professional experience building or operating platforms that serve Java/JVM-based backend systems at scale.
- Strong software architecture fundamentals: understands distributed system tradeoffs, service boundaries, API design, and data consistency patterns — not just the infrastructure layer.
- Hands-on proficiency with the JVM internals relevant to production operations: garbage collection tuning, classloading, thread modeling, heap analysis, and JIT behavior.
- Comfortable reading and reasoning about Java application code to diagnose performance issues — bridges the gap between software engineer and infrastructure engineer.
Proven Track Record Building Internal Developer Platforms
- Demonstrated experience designing and delivering developer-facing platforms (service catalogs, golden-path templates, scaffolding tooling) that measurably improved engineering autonomy.
- Deep expertise in CI/CD systems, not just configuring pipelines but optimizing them: remote caching, test parallelization, flakiness detection, and incremental build strategies.
- Experience instrumenting and reporting on Developer Experience (DX) metrics: DORA metrics, build time percentiles, pipeline reliability rates, and time-to-first-deployment for new services.
- Treats the internal platform as a product, with internal developer teams as customers — conducts discovery, measures adoption, and iterates based on developer feedback.
Observability Engineering — Building the Stack.
- Expert-level hands-on experience with the full observability stack: metrics (Prometheus/Grafana), distributed tracing (OpenTelemetry, Tempo/Jaeger), structured logging, and continuous profiling.
- Designs and maintains the pipelines, SDKs, and platform integrations that make it trivially easy for product teams to instrument their own services.
- Deep familiarity with SLO/SLI frameworks: defines error budget policies, configures multi-window burn rate alerts, and coaches squads on reliability ownership.
- Experience with continuous profiling tools in production JVM environments (e.g., async-profiler, Pyroscope, or equivalent) and the ability to translate flame graphs into actionable code-level fixes.
Operating Systems & Infrastructure Foundations
- Strong Linux fundamentals: process scheduling, memory management, file descriptors, networking stack, and cgroups/namespaces as they relate to container and JVM behavior.
- Understands container runtime behavior (Docker, containerd) and Kubernetes scheduling deeply enough to tune resource allocation, JVM heap sizing, and startup probes for Java workloads.
Strong Systematic Problem Solving & Engineering Judgment
- Applies a structured, data-driven methodology to diagnose complex issues across the build, runtime, and infrastructure stack — moves from symptoms to root cause without guesswork.
- Exercises sound architectural judgment: knows when to build vs. adopt, and can argue both sides rigorously using data and first-principles reasoning.
- Proactively identifies and eliminates toil — measures the cost of manual work, proposes automation, and follows through to delivery.
- Communicates technical findings clearly to both engineers and non-technical stakeholders, with the ability to translate platform complexity into business impact.
Developer-First Mindset & Culture Multiplier
- Approaches every platform decision through the lens of developer experience — actively solicits feedback from product squads and treats friction as a bug.
- Early adopter of AI-assisted engineering workflows, with demonstrated experience integrating LLM tooling into developer workflows beyond personal productivity (e.g., team-level tooling, automated documentation, or AI-assisted diagnostics).
- Acts as a force multiplier: mentors product engineers on platform capabilities, architectural patterns, and observability ownership — reducing dependency on the platform team over time.
- Communicates effectively across distributed, cross-functional teams in a fast-moving environment.
