At Teleflex, a Software Engineer plays a critical role in designing, developing, and sustaining the software systems that power life-saving medical devices and manufacturing technologies. Unlike general consumer-tech software roles, engineering at Teleflex directly impacts patient outcomes. The software you write, validate, or test ensures the safety, efficacy, and reliability of complex clinical instruments, vascular access devices, surgical tools, and anesthesia delivery systems used in hospitals worldwide. This position bridges the gap between hardware execution and digital control. Whether you are developing embedded firmware in C/C++, writing automated testing scripts, or designing software validation protocols for production lines, your work must meet the highest standards of quality and regulatory compliance. The engineering team at Teleflex operates in a highly collaborative environment where software, hardware, quality, and manufacturing teams work in unison to bring innovative medical technologies from concept to the clinical field. For a passionate engineer, this role offers the unique challenge of solving complex technical problems under stringent safety guidelines. You will work on sophisticated codebases where memory management, real-time constraints, and deterministic behavior are paramount.

PracHub editorial advice for the preparation topics above.
Master the C/C++ basics
Review core language keywords and memory concepts thoroughly. Being able to explain exactly how volatile or static affects variable allocation in memory is a common differentiator in technical rounds.
Highlight regulatory experience
If you have worked under FDA, FAA, or other highly regulated frameworks, emphasize this. Understanding how to write software within a strict quality management system is a massive asset at Teleflex.
Prepare your project stories
Use the STAR method (Situation, Task, Action, Result) to structure your behavioral answers. Focus on engineering projects where you had to collaborate across teams or solve a difficult hardware-software integration bug.
Show passion for the mission
Teleflex is dedicated to improving patient outcomes. Expressing a genuine interest in medical technology and explaining why you want to apply your engineering skills to life-saving products will resonate strongly with your interviewers.
Ask thoughtful questions
Use the end of your interviews to ask about the team's development processes, how they handle software validation, or what the integration between hardware and software looks like on their current projects. This demonstrates your proactive engineering mindset.

Find version gaps and relay lag with window functions
outbox_event holds event_id, aggregate_type, aggregate_id, aggregate_version, event_type, payload, status ('pending','published','dead'), attempts, created_at, published_at. A projection is missing rows and you must decide whether the relay skipped events or the consumer dropped them. Write three queries over the last seven days: one listing every aggregate_id whose published aggregate_version sequence has a hole, one giving per-day counts with a running total, and one returning the newest published event per aggregate. For each, say where the window function is evaluated relative to WHERE and LIMIT. PostgreSQL 16.
Approach
- Gaps: compute lead(aggregate_version) OVER (PARTITION BY aggregate_id ORDER BY aggregate_version) in a subquery, then filter next_version <> aggregate_version + 1 in the outer query. Window functions are evaluated after WHERE, GROUP BY and HAVING and before the outer ORDER BY and LIMIT, so the predicate cannot sit in the same WHERE clause and PostgreSQL 16 has no QUALIFY.
- Say what the seven-day filter does to the answer: it truncates every partition, so the first row per aggregate has no predecessor inside the window and a hole spanning the boundary is invisible. Widen the window, or join to resource.version as the authority for the true maximum.
- Running total: SELECT date_trunc('day', created_at) AS d, count() AS n, sum(count()) OVER (ORDER BY date_trunc('day', created_at) ROWS UNBOUNDED PRECEDING). An aggregate inside a window call is legal because grouping runs before windowing. The grouping key is unique per row here so ROWS and RANGE agree, but write the frame anyway — over ungrouped rows with tied timestamps the default RANGE frame pulls in every peer row and the total jumps.
- Newest per aggregate: DISTINCT ON (aggregate_id) ... ORDER BY aggregate_id, aggregate_version DESC is the cheap PostgreSQL-only form when an index matches that order; row_number() OVER (PARTITION BY aggregate_id ORDER BY aggregate_version DESC) = 1 is the portable form and needs a subquery for the same evaluation-order reason as the gap query.
Follow-up
- Relay failover redelivers events. Does a duplicate break the gap query, and how would you detect one from this table alone?
- Turn the gap check into a continuous monitor rather than a query someone runs after an incident. What does it watch?
Denormalise tenant onto revisions and backfill it live
resource_revision (revision_id, resource_id, version, actor_user_id, change_kind, patch, request_id, created_at) has 400M rows and no tenant column; tenant_id lives only on resource. Two reads need it: a tenant-scoped audit feed ordered by created_at DESC, and an offboarding purge. Both join back to resource today. Justify adding tenant_id to resource_revision against those two reads, name the anomaly the copy introduces and the constraint that prevents it, then give the ordered migration for a live table taking 1.2k writes/second — the lock each step takes, how the backfill is batched, and where each step stops being reversible. PostgreSQL 16.
Approach
- Justify from the access path rather than from taste. Without the column, the audit feed either scans resource_revision by created_at and discards other tenants' rows, or resolves the tenant's resource_ids first and probes with them — both proportional to the tenant's whole history rather than to one page. With (tenant_id, created_at DESC, revision_id DESC) it is a seek that stops at 50 rows, and the purge becomes a ranged delete instead of a join.
- Name the cost exactly: a second copy of a fact can disagree with the first. Make the disagreement unwritable rather than documented — add UNIQUE (resource_id, tenant_id) on resource so it can serve as a foreign-key target, then FOREIGN KEY (resource_id, tenant_id) REFERENCES resource (resource_id, tenant_id) on the revision table. A revision can then only ever carry its parent's tenant.
- Step one, expand: ALTER TABLE resource_revision ADD COLUMN tenant_id BIGINT NULL, with no default, so it is a catalogue change and no rewrite. It still needs ACCESS EXCLUSIVE for an instant, and that instant queues behind the longest open transaction on the table while every later query queues behind it — set lock_timeout to 2s and retry rather than wait.
- Step two, dual-write: deploy the writer that populates tenant_id on every new revision while reads still use the join. Reversible by redeploying the previous build, because nothing reads the column yet.
Follow-up
- The backfill is half finished and a rollback is required. What state is the table in, and what does the previous build do with a half-populated column?
- How do you verify the backfill actually finished, given rows are still being inserted while it runs?
