Trino SQL is the distributed query engine that LatAm data teams use to query petabyte-scale data across Hadoop, Presto, Iceberg, and cloud data warehouses without moving the data. If you're building analytics infrastructure that spans AWS Redshift, Google BigQuery, Delta Lake, and legacy databases simultaneously, you need a Trino expert. South connects you with senior Trino architects from Brazil and Argentina who've handled massive federated queries for fintech and e-commerce platforms. Get matched in days, not months. Start your search with South today.
Trino is an open-source distributed SQL query engine that lets you query data where it lives, across heterogeneous sources. Originally developed at Facebook as Presto, Trino is now the maintained fork used by companies like Uber, Netflix, and Airbnb. It's a Java-based engine that connects to any data source via a connector: Hive, HDFS, S3, PostgreSQL, MySQL, MongoDB, Cassandra, Elasticsearch, and cloud data warehouses like Snowflake and BigQuery.
Unlike traditional ETL, Trino brings the query to the data. A single SELECT statement can join tables across three different data warehouses without intermediate data movement. This architectural approach has made Trino indispensable for companies with polyglot data stacks.
GitHub shows 8,000+ stars and active development with 400+ contributors. The Trino ecosystem is particularly strong in LatAm, where Brazilian fintech companies (Nubank, Inter) have large-scale Trino deployments supporting real-time analytics. Argentina's data engineering community has also adopted Trino for cost-efficient analytics on AWS.
The language is SQL itself, which is both Trino's strength and its constraint. You're not learning new syntax; you're learning connector semantics, optimization strategies, and how to manage distributed query execution across unreliable networks.
Hire a Trino expert when you own or operate a data stack with multiple systems and you need unified query access without managing ETL pipelines. Common scenarios: you have data in S3 and PostgreSQL and need a single source of truth for analytics. You're running Hadoop and want to migrate to a cloud warehouse but can't afford downtime for a full data migration. You've chosen a cloud data warehouse but still have legacy OLTP databases that must be queryable as-is.
Trino is not the right choice if your data is small enough to fit in a single system, or if you need transactional guarantees. Trino is read-optimized and append-based. It excels at OLAP (analytical) workloads, not OLTP. If you're building real-time operational dashboards with sub-second latency, you might pair Trino with a caching layer like Redis or Apache Druid.
The ideal team structure for a Trino-first data stack is: one senior Trino architect (5+ years), two data engineers who write SQL and manage connectors, and one DevOps engineer to manage the cluster. If you're starting smaller, a single senior Trino engineer can handle both architecture and pipeline work for the first 6 months, but growth will demand specialization quickly.
Trino shines in scale-up and enterprise settings with 10+ data sources. If you're a small startup with one data warehouse, investing in Trino expertise is premature. Use a simpler orchestration tool like dbt until you've outgrown a single system.
A strong Trino engineer must understand distributed systems at a deep level. They know query execution plans, cost models, and how to diagnose why a query ran in 2 hours instead of 2 minutes. They've managed Trino clusters with thousands of tables and millions of daily queries. Nice-to-haves include experience with specific connectors (Iceberg, Delta Lake, Hive) and optimization techniques like partition pruning and predicate pushdown.
Red flags: engineers who think SQL is the hard part. The SQL in Trino is standard; the hard part is understanding the connector layer and distributed execution. If they can't explain how a join executes across multiple systems, move on. Also watch for cluster management confusion. Trino itself is a query engine; managing the underlying compute (Hadoop, Kubernetes) is a different skill set.
Junior (1-2 years): Knows SQL well. Can write and optimize basic Trino queries. Understands one or two connectors (e.g., Hive and PostgreSQL). Can execute pre-designed Trino setups but can't architect from scratch. Needs guidance on cluster tuning and cost management.
Mid-level (3-5 years): Comfortable managing 5+ connectors. Can architect a federated query layer for a mid-size data stack. Understands query performance and can optimize slow queries. Can troubleshoot connector issues and manage Trino security (access control, encryption). Knows how to integrate Trino with orchestration tools like Airflow.
Senior (5+ years): Has designed Trino deployments serving 500+ daily users across enterprise datasets. Understands all optimization levers: query caching, reserved capacity pools, dynamic filtering. Can architect migrations from other systems to Trino. Knows when Trino is the wrong choice and what the alternatives are. Has experience with cluster scaling, HA setups, and cost management in production.
For remote and nearshore work, Trino engineers in LatAm typically work Brazil Standard Time (UTC-3) or Argentina Standard Time (UTC-3), giving you 5-8 hours of real-time overlap with US East Coast teams. Soft skills: they should be communicative about performance bottlenecks and able to explain complex query plans to non-technical stakeholders.
Tell me about a time you redesigned a query layer to improve performance. Listen for: specific metrics (query time improvement), connectors involved, and whether they optimized at the Trino level or connector level. A strong answer mentions understanding upstream bottlenecks.
You've got a Trino cluster that's running slow. Walk me through your debugging process. Good answers start with identifying slow queries, then drilling into explain plans, then checking resource utilization, then investigating connector lag. They should mention tools like the Trino UI, system tables, and connector logs.
Describe a migration you led from one data warehouse to Trino. Listen for: data volume, downtime constraints, validation strategy. Did they write comparison queries to ensure consistency between old and new systems? This is the hallmark of a senior engineer.
When have you said no to using Trino and chosen something else instead? Maturity signal. A great answer: 'We had sub-second analytics requirements, so we used a columnar cache (Druid) in front of Trino.' Shows they understand trade-offs.
How do you handle costs in a Trino deployment? Senior engineers talk about resource pools, reserved capacity, and cost attribution per team. They might mention tools like Fivetran or dbt that integrate with Trino for cost tracking.
Explain what happens when you execute a join between a table in PostgreSQL and a table in S3 via Trino. Evaluation: they should explain that Trino pulls data from both sources, doesn't push joins to the source systems, and that the join happens in Trino's workers. They might mention how to optimize via predicate pushdown to reduce data movement. Strong answers mention cost implications.
What's the difference between a partition and a bucketing strategy, and when would you use each in Trino? Evaluation: understand that partitioning is primarily for data discovery (predicate pushdown), bucketing is for join optimization. Not all connectors support bucketing equally. A great answer acknowledges these differences per connector.
You need to query 500 GB of Parquet files in S3 via Trino. Your query is running 15 minutes. What are three optimizations you'd try? Evaluation: partition pruning (add WHERE clause on partition columns), projection pushdown (select only needed columns), and file format optimization (Parquet is good, but columnar compression settings matter). They might mention increasing workers or tuning the task.max-run-time property.
Explain Trino's execution model. What's a stage? What's a task? Evaluation: they should know that a query is split into stages, each stage is split into tasks, and tasks run in parallel across workers. They should explain how Trino distributes work. A strong answer mentions how skew in data distribution affects task runtime.
How would you implement row-level security in Trino? Evaluation: Trino doesn't have built-in RLS; you implement it via stored procedures, views with filters, or external authorization systems. They might mention Okera or other RLS tools. An excellent answer acknowledges the complexity and suggests using the source system's RLS where possible.
You're given three data sources: PostgreSQL (orders), S3 Parquet (logs), and Redshift (customer segments). Write a Trino query that joins all three to calculate average order value per segment for the last 30 days. Then optimize the query for cost.
Scoring: basic join correctness (60%), partition pruning and column selection (20%), understanding of connector costs (20%). A strong submission includes comments explaining optimization decisions.
LatAm Rates (2026):
US Market Comparison:
LatAm Trino talent is concentrated in Brazil (São Paulo, Rio) and Argentina (Buenos Aires), where fintech and data infrastructure companies have created deep expertise. Rates in Brazil tend to be 5-10% lower than Argentina due to currency dynamics, but talent quality is comparable. The premium for a senior Trino architect in LatAm is justified: they've worked on petabyte-scale systems and understand production constraints that junior engineers rarely encounter.
Brazil and Argentina produce some of the world's best Trino engineers. This isn't coincidental. Nubank, Inter, and other Brazilian fintechs have massive polyglot data stacks where Trino is the nerve system for real-time analytics. Engineers who've worked on these systems understand production-grade Trino at a depth that's rare globally. Argentina has a similarly strong data engineering community centered around Buenos Aires, with companies like Mercado Libre pushing the boundaries of Trino optimization.
Time zone alignment is a major win. Most LatAm Trino engineers are UTC-3 to UTC-5, giving you 5-8 hours of real-time collaboration with US East Coast teams. For a data infrastructure project, synchronous problem-solving with your Trino architect is worth thousands in avoided mistakes.
English proficiency is high among LatAm data engineers. They've learned Trino, dbt, and SQL in English-language documentation and communities. Communication about complex technical issues is clear and direct. Cultural alignment is strong too: data engineers in LatAm tend to be pragmatic and cost-conscious, which matches the mindset required for running efficient Trino clusters.
Cost efficiency is real but secondary to capability. You're saving 40-60% on a senior LatAm Trino engineer compared to US rates, but you're also getting someone who's solved harder problems at larger scale. This is the best ROI hire in data engineering.

Trino is used for unified querying across multiple data sources, federation analytics, and cost-effective alternatives to moving data into a single warehouse. Companies use it to query S3 raw data, production databases, and cloud warehouses in a single query without ETL.
Trino can handle real-time analytics if your latency tolerance is seconds (5-30 second queries). If you need sub-second latency, pair Trino with a caching layer like Druid or Redis. Trino is optimized for OLAP, not OLTP.
Trino is the maintained, production-grade fork of Presto. Choose Trino. Apache Drill is older and less actively developed. If you're already on Presto, migrate to Trino; most use cases benefit from the newer optimizations.
Senior Trino architects in LatAm cost $105,000-$145,000/year, roughly 40% less than US rates for equivalent talent. Brazil and Argentina are the primary talent sources.
You'll interview qualified candidates within 48 hours of describing your needs. Most placements are finalized within 1-2 weeks. We move fast because we pre-vet before matching.
